**Note:** Wacom does not officially support Linux. Linux support is provided by the [Linux Wacom Project](https://linuxwacom.github.io/). This guide was started for *USB* based Wacom tablets, so much of the info in here focuses on that. Usually it is recommended to rely on [Xorg](/index.php/Xorg "Xorg")'s auto-detection or to use a **dynamic** setup. However for an *internal* tablet device one might consider a **static** Xorg setup in case autodetection does not work. A static [Xorg](/index.php/Xorg "Xorg") setup is usually not able to recognize your Wacom tablet when it is connected to a different *USB* port or even after unplugging and replugging it into the same port, and as such it should be considered as deprecated. ## Contents * [1 Installation](#Installation) * [1.1 Automatic setup](#Automatic_setup) * [1.2 Manual setup](#Manual_setup) * [1.2.1 Dynamic with udev](#Dynamic_with_udev) * [1.2.1.1 USB-devices](#USB-devices) * [1.2.1.2 Serial devices](#Serial_devices) * [1.2.2 Static setup](#Static_setup) * [1.2.3 Xorg configuration](#Xorg_configuration) * [2 Configuration](#Configuration) * [2.1 General concepts](#General_concepts) * [2.1.1 Temporary configuration](#Temporary_configuration) * [2.1.2 Permanent configuration](#Permanent_configuration) * [2.1.3 Changing orientation](#Changing_orientation) * [2.1.4 Remapping Buttons](#Remapping_Buttons) * [2.1.4.1 Finding out the button IDs](#Finding_out_the_button_IDs) * [2.1.4.2 The syntax](#The_syntax) * [2.1.4.3 Some examples](#Some_examples) * [2.1.4.4 Execute custom commands](#Execute_custom_commands) * [2.1.5 LEDs](#LEDs) * [2.1.6 TwinView Setup](#TwinView_Setup) * [2.1.6.1 Temporary TwinView Setup](#Temporary_TwinView_Setup) * [2.1.7 Xrandr Setup](#Xrandr_Setup) * [2.2 Pressure curve](#Pressure_curve) * [2.3 Adjusting aspect ratios](#Adjusting_aspect_ratios) * [2.3.1 Reducing the drawing area height](#Reducing_the_drawing_area_height) * [2.3.2 Reducing the screen area width](#Reducing_the_screen_area_width) * [2.4 Using kcm-wacomtablet](#Using_kcm-wacomtablet) * [3 Application-specific configuration](#Application-specific_configuration) * [3.1 Blender](#Blender) * [3.2 GIMP](#GIMP) * [3.3 Inkscape](#Inkscape) * [3.4 Krita](#Krita) * [3.5 VirtualBox](#VirtualBox) * [4 Troubleshooting](#Troubleshooting) * [4.1 Unknown device_type](#Unknown_device_type) * [4.2 Tablet recognized but xsetwacom and similar tools do not display it](#Tablet_recognized_but_xsetwacom_and_similar_tools_do_not_display_it) * [5 References](#References) ## Installation 1. **Check if the kernel recognizes your tablet** In case of a USB tablet, plug it in and check `lsusb`, `dmesg | grep -i wacom` or `/proc/bus/input/devices`. When your tablet isn't recognized but supported by a more recent driver than the one in the kernel try to install [input-wacom-dkms](https://aur.archlinux.org/packages/input-wacom-dkms/). 2. **Install the Wacom drivers** Install the [xf86-input-wacom](https://www.archlinux.org/packages/?name=xf86-input-wacom) package. If it doesn't work try the less stable [xf86-input-wacom-git](https://aur.archlinux.org/packages/xf86-input-wacom-git/). ### Automatic setup Newer versions of X should be able to automatically detect and configure your device. Before going any further, restart X so the new udev rules take effect. Test if your device was recognized completely (i.e., that both pen and eraser work, if applicable), by issuing command ``` $ xsetwacom list devices ``` which should detect all devices with type, for example ``` Wacom Bamboo 2FG 4x5 Pen stylus id: 8 type: STYLUS Wacom Bamboo 2FG 4x5 Pen eraser id: 9 type: ERASER Wacom Bamboo 2FG 4x5 Finger touch id: 13 type: TOUCH Wacom Bamboo 2FG 4x5 Finger pad id: 14 type: PAD ``` You can also test it by opening [gimp](https://www.archlinux.org/packages/?name=gimp) or [xournal](https://www.archlinux.org/packages/?name=xournal) and checking the extended input devices section, or whatever tablet-related configuration is supported by the software of your choice. For this to work you do not need any `xorg.conf` file, any configurations are made in files in the `/etc/X11/xorg.conf.d/` folder. If everything is working you can skip the manual configuration and **proceed** to the configuration section to learn how to further customize your tablet. With the arrival of Xorg 1.8 support for HAL was dropped in favor of [udev](/index.php/Udev "Udev") which might break auto-detection for some tablets as fitting udev rules might not exist yet, so you may need to write your own. The *xf86-input-wacom* driver was designed to work with the Xorg server so there may be problems if you're running your desktop environment in Wayland (The default for Gnome). ### Manual setup A manual configuration is done in `/etc/X11/xorg.conf` or in a separate file in the `/etc/X11/xorg.conf.d/` directory. The Wacom tablet device is accessed using a input event interface in `/dev/input/` which is provided by the kernel driver. The interface number `event??` is likely to change when unplugging and replugging into the same or especially a different *USB* port. Therefore it is wise to not refer to the device using its concrete `event??` interface (**static** configuration) but by letting *udev* dynamically create a symbolic link to the correct `event` file (**dynamic** configuration). #### Dynamic with udev **Note:** In AUR there is wacom-udev package, which includes udev-rules-file. You might skip this part and move on to the `xorg.conf` configuration if you are using the wacom-udev package from AUR. Assuming *udev* is already installed you simply need to install [wacom-udev](https://aur.archlinux.org/packages/wacom-udev/) from the [AUR](/index.php/AUR "AUR"). ##### USB-devices After (re-)plugging in your *USB*-tablet (or at least after rebooting) some symbolic links should appear in `/dev/input` referring to your tablet device. ``` $ ls /dev/input/wacom* /dev/input/wacom /dev/input/wacom-stylus /dev/input/wacom-touch ``` If not, your device is likely to be not yet included in the *udev* configuration from *wacom-udev* which resides in `/usr/lib/udev/rules.d/10-wacom.rules`. It is a good idea to copy the file e.g. to `10-my-wacom.rules` before modifying it, else it might be reverted by a package upgrade. Add your device to the file by duplicating some line of another device and adapting *idVendor*,*idProduct* and the symlink name to your device. The two id's can be determined using ``` $ lsusb | grep -i wacom Bus 002 Device 007: ID 056a:0062 Wacom Co., Ltd ``` In this example idVendor is 056a and idProduct 0062. In case you have device with touch (e.g. Bamboo Pen&Touch) you might need to add a second line for the touch input interface. For details check the linuxwacom wiki [Fixed device files with udev](http://linuxwacom.sourceforge.net/wiki/index.php/Fixed_device_files_with_udev). Save the file and reload udev's configuration profile using the command *udevadm control --reload-rules* Check again the content of */dev/input* to make sure that the *wacom* symlinks appeared. Note that you may need to plug-in the tablet again for the device to appear. The files of further interest for the *Xorg* configuration are `/dev/input/wacom` and for a touch-device also `/dev/input/wacom_touch`. ##### Serial devices The [wacom-udev](https://aur.archlinux.org/packages/wacom-udev/) should also include support for serial devices. Users of serial tablets might be also interested in the inputattach tool from [linuxconsole](https://www.archlinux.org/packages/?name=linuxconsole) package. The inputattach command allows to bind serial device into /dev/input tree, for example with: ``` # inputattach --w8001 /dev/ttyS0 ``` See *man inputattach* for help about available options. As for USB devices one should end up with a file `/dev/input/wacom` and proceed with the *Xorg* configuration. #### Static setup If you insist in using a static setup just refer to your tablet in the *Xorg* configuration in the next section using the correct `/dev/input/event??` files as one can find out by looking into `/proc/bus/input/devices`. #### Xorg configuration In either case, dynamic or static setup you got now one or two files in `/dev/input/` which refer to the correct input event devices of your tablet. All that is left to do is add the relevant information to `/etc/X11/xorg.conf`, or a dedicated file under `/etc/X11/xorg.conf.d/`. The exact configuration depends on your tablet's features of course. `xsetwacom list devices` might give helpful information on what *InputDevice* sections are needed for your tablet. An example configuration for a *Volito2* might look like this ``` Section "InputDevice" Driver "wacom" Identifier "stylus" Option "Device" "/dev/input/wacom" # or the corresponding event?? for a static setup Option "Type" "stylus" Option "USB" "on" # USB ONLY Option "Mode" "Relative" # other option: "Absolute" Option "Vendor" "WACOM" Option "tilt" "on" # add this if your tablet supports tilt Option "Threshold" "5" # the official linuxwacom howto advises this line EndSection Section "InputDevice" Driver "wacom" Identifier "eraser" Option "Device" "/dev/input/wacom" # or the corresponding event?? for a static setup Option "Type" "eraser" Option "USB" "on" # USB ONLY Option "Mode" "Relative" # other option: "Absolute" Option "Vendor" "WACOM" Option "tilt" "on" # add this if your tablet supports tilt Option "Threshold" "5" # the official linuxwacom howto advises this line EndSection Section "InputDevice" Driver "wacom" Identifier "cursor" Option "Device" "/dev/input/wacom" # or the corresponding event?? for a static setup Option "Type" "cursor" Option "USB" "on" # USB ONLY Option "Mode" "Relative" # other option: "Absolute" Option "Vendor" "WACOM" EndSection ``` Make sure that you also change the path (`"Device"`) to your mouse, as it will be `/dev/input/mouse_udev` now. ``` Section "InputDevice" Identifier "Mouse1" Driver "mouse" Option "CorePointer" Option "Device" "/dev/input/mouse_udev" Option "SendCoreEvents" "true" Option "Protocol" "IMPS/2" Option "ZAxisMapping" "4 5" Option "Buttons" "5" EndSection ``` Add this to the *ServerLayout* section ``` InputDevice "cursor" "SendCoreEvents" InputDevice "stylus" "SendCoreEvents" InputDevice "eraser" "SendCoreEvents" ``` And finally make sure to update the identifier of your mouse in the *ServerLayout* section – as mine went from ``` InputDevice "Mouse0" "CorePointer" ``` to ``` InputDevice "Mouse1" "CorePointer" ``` ## Configuration **Note:** If you do not [adjust your aspect ratios](#Adjusting_aspect_ratios), your lines may be slightly vertically skewed. ### General concepts The configuration can be done in two ways temporary using the `xsetwacom` tool, which is included in *xf86-input-wacom* or permanent in `xorg.conf` or better in a extra file in `/etc/X11/xorg.conf.d`. The possible options are identical so it is recommended to first use `xsetwacom` for testing and later add the final config to the *Xorg* configuration files. #### Temporary configuration For the beginning it is a good idea to inspect the default configuration and all possible options using the following commands. ``` $ xsetwacom list devices # list the available devices for the get/set commands Wacom Bamboo 16FG 4x5 Finger touch id: 12 type: TOUCH Wacom Bamboo 16FG 4x5 Finger pad id: 13 type: PAD Wacom Bamboo 16FG 4x5 Pen stylus id: 17 type: STYLUS Wacom Bamboo 16FG 4x5 Pen eraser id: 18 type: ERASER $ xsetwacom get "Wacom Bamboo 16FG 4x5" all # using the device name $ xsetwacom get 17 all # or equivalently use the device id $ xsetwacom list parameters # to get an explanation of the Options $ man wacom # get even more details ``` **Caution**, do not use the device id when writing shell scripts to set some options as the ids might change after an hotplug. Options can be changed with the `set` command. Some useful examples are ``` $ xsetwacom set "Wacom Bamboo 16FG 4x5 Finger touch" ScrollDistance 50 # change scrolling speed $ xsetwacom set "Wacom Bamboo 16FG 4x5 Finger touch" Gesture off # disable multitouch gestures $ xsetwacom set "Wacom Bamboo 16FG 4x5 Finger touch" Touch off # disable touch ``` **Note:** You can reset your temporary configuration at any time by unplugging and replugging in your tablet. **Note:** There are some configurations that can only be set up dynamically with xsetwacom. In those cases it is possible to run a script that configures the device calling xsetwacom every time the device is plugged in. See [[1]](http://unix.stackexchange.com/a/290940/89955). #### Permanent configuration To make a permanent configuration the preferred way for *Xorg*>1.8 is to create a new file in `/etc/X11/xorg.conf.d` e.g. `52-wacom-options.conf` with the following content. `/etc/X11/xorg.conf.d/52-wacom-options.conf` ``` Section "InputClass" Identifier "Wacom Bamboo stylus options" MatchDriver "wacom" MatchProduct "Pen" # Apply custom Options to this device below. Option "Rotate" "none" Option "RawSample" "20" Option "PressCurve" "0,10,90,100" EndSection Section "InputClass" Identifier "Wacom Bamboo eraser options" MatchDriver "wacom" MatchProduct "eraser" # Apply custom Options to this device below. Option "Rotate" "none" Option "RawSample" "20" Option "PressCurve" "5,0,100,95" EndSection Section "InputClass" Identifier "Wacom Bamboo touch options" MatchDriver "wacom" MatchProduct "Finger" # Apply custom Options to this device below. Option "Rotate" "none" Option "ScrollDistance" "18" Option "TapTime" "220" EndSection Section "InputClass" Identifier "Wacom Bamboo pad options" MatchDriver "wacom" MatchProduct "pad" # Apply custom Options to this device below. Option "Rotate" "none" # Setting up buttons Option "Button1" "1" Option "Button2" "2" Option "Button3" "3" Option "Button4" "0" EndSection ``` The identifiers can be set arbitrarily. The option names are (except for the buttons) identical to the ones listed by `xsetwacom list parameters` and especially also in [wacom(4)](https://jlk.fjfi.cvut.cz/arch/manpages/man/wacom.4). As noted in [#Remapping Buttons](#Remapping_Buttons) the button ids seem to be different than the ones for `xsetwacom`. **Tip:** *xsetwacom* can display the output in xorg.conf format by using `xsetwacom -x get`. #### Changing orientation If you want to use your tablet in a different orientation you have to tell this to the driver, else the movements do not cause the expected results. This is done by setting the **Rotate** option for all devices. Possible orientations are **none**,**cw**,**ccw** and **half**. A quick way is e.g. ``` $ for i in 12 13 17 18; do xsetwacom set $i Rotate half; done # remember the ids might change when hotplugging ``` or use the following script like this `./wacomrot.sh half` `wacomrot.sh` ``` #!/bin/bash device="Wacom Bamboo 16FG 4x5" stylus="$device Pen stylus" eraser="$device Pen eraser" touch="$device Finger touch" pad="$device Finger pad" xsetwacom set "$stylus" Rotate $1 xsetwacom set "$eraser" Rotate $1 xsetwacom set "$touch" Rotate $1 xsetwacom set "$pad" Rotate $1 ``` #### Remapping Buttons It is possible to remap the buttons with hotkeys. * Check [Simple web-based GUI for xsetwacom](http://planetedessonges.org:8010/wakey/), supports *bamboo small* but more models may come. ##### Finding out the button IDs Sometimes it needs some trial&error to find the correct button IDs. For me they even differ for `xsetwacom` and the `xorg.conf` configuration. Very helpful tools are `xev` or `xbindkeys -mk`. An easy way to proceed is to temporarily assign keystrokes to your tablet's buttons like this: ``` $ xsetwacom set "Wacom Bamboo 16FG 4x5 Finger pad" Button 1 'key a' $ xsetwacom set "Wacom Bamboo 16FG 4x5 Finger pad" Button 2 'key b' $ xsetwacom set "Wacom Bamboo 16FG 4x5 Finger pad" Button 3 'key c' $ # and so on ``` Then fire up `xev` from a terminal window, place your mouse cursor above the window and hit the buttons and write down the IDs. ``` $ xev | grep KeyPress -A 5 ``` ##### The syntax The syntax of `xsetwacom` is flexible but not very well documented. The general mapping syntax (extracted from the source code) for xsetwacom 0.17.0 is the following. ``` KEYWORD [ARGS...] [KEYWORD [ARGS...] ...] KEYWORD + ARGS: key [+,-]KEY [[+,-]KEY ...] where +:key down, -:key up, no prefix:down and up button BUTTON [BUTTON ...] (1=left,2=middle,3=right mouse button, 4/5 scroll mouse wheel) modetoggle toggle absolute/relative tablet mode displaytoggle toggle cursor movement among all displays which include individual screens plus the whole desktop for the selected tool if it is not a pad. When the tool is a pad, the function applies to all tools that are asssociated with the tablet BUTTON: button ID as integer number KEY: MODIFIER, SPECIALKEY or ASCIIKEY MODIFIER: (each can be prefix with an **l** or an **r** for the left/right modifier (no prefix = left) ctrl=ctl=control, meta, alt, shift, super, hyper SPECIALKEY: f1-f35, esc=Esc, up,down,left,right, backspace=Backspace, tab, PgUp,PgDn ASCIIKEY: (usual characters the key produces, e.g. a,b,c,1,2,3 etc.) ``` ##### Some examples ``` $ xsetwacom set "Wacom Bamboo 16FG 4x5 Finger pad" Button 1 3 # right mouse button $ xsetwacom set "Wacom Bamboo 16FG 4x5 Finger pad" Button 1 "key +ctrl z -ctrl" $ xsetwacom get "Wacom Bamboo 16FG 4x5 Finger pad" Button 1 key +Control_L +z -z -Control_L $ xsetwacom set "Wacom Bamboo 16FG 4x5 Finger pad" Button 1 "key +shift button 1 key -shift" ``` even little macros are possible ``` $ xsetwacom set "Wacom Bamboo 16FG 4x5 Finger pad" Button 1 "key +shift h -shift e l l o" ``` **Note:** There seems to be a bug in the *xf86-input-wacom* driver version 0.17.0, at least for my *Wacom Bamboo Pen & Touch*, but I guess this holds in general. It causes the keystrokes not to be overwritten correctly. ``` $ xsetwacom set "Wacom Bamboo 16FG 4x5 Finger pad" Button 1 "key a b c" # press button 1 -> abc $ xsetwacom set "Wacom Bamboo 16FG 4x5 Finger pad" Button 1 "key d" # press button 1 -> dbc WRONG! ``` A simple workaround is to reset the mapping by mapping to "": ``` $ xsetwacom set "Wacom Bamboo 16FG 4x5 Finger pad" Button 1 "" # to reset the mapping $ xsetwacom set "Wacom Bamboo 16FG 4x5 Finger pad" Button 1 "key d" # press button 1 -> d ``` **Note:** If you try to run a script with `xsetwacom` commands from a udev rule, you might find that it will not work, as the wacom input devices will not be ready at the time. A workaround is to add `sleep 1` at the beginning of your script. ##### Execute custom commands Mapping custom commands to the buttons is a little bit tricky but actually very simple. First, install [xbindkeys](https://www.archlinux.org/packages/?name=xbindkeys). To get well defined button codes add the following to your permanent configuration file, e.g. `/etc/X11/xorg.conf.d/52-wacom-options.conf` in the InputClass section of your **pad** device. Map the tablet's buttons to some unused button ids. ``` # Setting up buttons (preferably choose the correct button order, so the topmost key is mapped to 10 and so on) Option "Button1" "10" Option "Button2" "11" Option "Button3" "12" Option "Button4" "13" ``` Then restart your *Xorg* server and verify the buttons using `xev` or `xbindkeys -mk`. Now set up your xbindkeys configuration, if you do not already have one you might want to create a default configuration ``` $ xbindkeys --defaults > ~/.xbindkeysrc ``` Then add your custom key mapping to `~/.xbindkeysrc`, for example ``` "firefox" m:0x10 + b:10 (mouse) "xterm" m:0x10 + b:11 (mouse) "xdotool key ctrl-z" m:0x10 + b:12 (mouse) "send-notify Test "No need for escaping the quotes"" m:0x10 + b:13 (mouse) ``` #### LEDs See the [sysfs-driver-wacom](https://www.kernel.org/doc/Documentation/ABI/testing/sysfs-driver-wacom) documentation. To make changes without requiring root permissions you will likely want to create a [udev](/index.php/Udev "Udev") rule like so: `/etc/udev/rules.d/99-wacom.rules` ``` # Give the users group permissions to set Wacom device LEDs. ACTION=="add", SUBSYSTEM=="hid", DRIVERS=="wacom", RUN+="/usr/bin/sh -c 'chown :users /sys/%p/wacom_led/*'" ``` Setting the Intuos OLEDs can be done using [i4oled](https://aur.archlinux.org/packages/i4oled/) from the AUR. #### TwinView Setup If you are going to use two Monitors the aspect ratio while using the Tablet might feel unnatural. In order to fix this you need to add ``` Option "TwinView" "horizontal" ``` To all of your Wacom-InputDevice entries in the `xorg.conf` file. You may read more about that [HERE](http://ubuntuforums.org/showthread.php?t=640898) ##### Temporary TwinView Setup For temporary mapping of a Wacom device to a single display **while preserving the aspect ratio**, [this script](https://gist.github.com/Quackmatic/6c19fe907945d735c045) may be used. This will letter-box the surface area of the device as required to ensure the input is not stretched on the display. This script may be executed in your `.xinitrc` file for it to automatically run. #### Xrandr Setup xrandr sets two monitors as one big screen, mapping the tablet to the whole virtual screen and deforming aspect ratio. For a solution see this thread: [archlinux forum](https://bbs.archlinux.org/viewtopic.php?pid=797617). If you just want to map the tablet to one of your screens, first find out what the screens are called ``` $ xrandr Screen 0: minimum 320 x 200, current 3840 x 1080, maximum 16384 x 16384 **HDMI-0** disconnected (normal left inverted right x axis y axis) **DVI-0** connected 1920x1080+0+0 (normal left inverted right x axis y axis) 477mm x 268mm 1920x1080 60.0*+ 1680x1050 60.0 ... **VGA-0** connected 1920x1080+1920+0 (normal left inverted right x axis y axis) 477mm x 268mm 1920x1080 60.0*+ 1680x1050 60.0 ... ``` Then you need to know what is the ID of your tablet. ``` $ xsetwacom list devices WALTOP International Corp. Slim Tablet stylus id: **12** type: STYLUS ``` In my case I want to map the tablet (ID: **12**) to the screen on the right, which is **VGA-0**. I can do that with this command ``` $ xsetwacom set **12** MapToOutput **"VGA-0"** ``` This should immediately work, no root necessary. Should this fail when using the nvidia binary driver, using **HEAD-0**, **HEAD-1** and so on to refer to the monitors may work. If xsetwacom replies with "Unable to find an output ..." an X11 geometry string of the form **WIDTHxHEIGHT+X+Y** can be specified instead of the screen identifier. In this example ``` $ xsetwacom set **12** MapToOutput **"1920x1080+1920+0"** ``` should also map the tablet to the screen on the right. Alternatively, you can use [this bash script](https://bitbucket.org/denilsonsa/small_scripts/src/3380435f92646190f860b87f566a39d0e215034c/xsetwacom_my_preferences.sh?at=default) to quickly map the tablet to one of your screens (or the entire desktop) and fix the aspect ratio. In case **xsetwacom** doesn't work, you can try **xinput**. First, you need to find your tablet's ID. ``` $ xinput list ``` In my case, the output is: ``` ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ Wacom Intuos PT S 2 Finger id=11 [slave pointer (2)] ⎜ ↳ Wacom Intuos PT S 2 Pad id=12 [slave pointer (2)] ⎜ ↳ USB Keyboard id=14 [slave pointer (2)] ⎜ ↳ SynPS/2 Synaptics TouchPad id=16 [slave pointer (2)] ⎜ ↳ TPPS/2 IBM TrackPoint id=17 [slave pointer (2)] ⎜ ↳ SteelSeries Kinzu V2 Gaming Mouse id=9 [slave pointer (2)] ⎜ ↳ Wacom Intuos PT S 2 Pen Pen (0x6281780c) id=20 [slave pointer (2)] ⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ Power Button id=6 [slave keyboard (3)] ↳ Video Bus id=7 [slave keyboard (3)] ↳ Sleep Button id=8 [slave keyboard (3)] ↳ Wacom Intuos PT S 2 Pen id=10 [slave keyboard (3)] ↳ USB Keyboard id=13 [slave keyboard (3)] ↳ AT Translated Set 2 keyboard id=15 [slave keyboard (3)] ↳ ThinkPad Extra Buttons id=18 [slave keyboard (3)] ↳ USB Keyboard id=19 [slave keyboard (3)] ``` This mean, my tablet's ID is **20**. Now we map it with **VGA-0** screen: ``` $ xinput map-to-output 20 VGA-0 ``` ### Pressure curve Use the [Wacom Pressure Curve and Threshold Graph](https://linuxwacom.github.io/bezier.html) to find P1=red (eg. 50,0) and P2=purple (eg. 100,80) of your desired curve. The x-axis is the input pressure you apply to the pen; the y-axis is the output pressure the application is given. You can change the pressure curve with: ``` $ xsetwacom set *stylus* PressureCurve *x1 y1 x2 y2* ``` ### Adjusting aspect ratios Drawing areas of tablets are generally more square than the usual widescreen display with a 16:9 aspect ratio, leading to a slight vertical compression of your input. To resolve such an aspect ratio mismatch you need to compromise by either reducing the drawing area height (called *Force Proportions* on Windows) or reducing the screen area width. The former wastes drawing area and the latter prevents you from reaching the right edge of your screen with your Stylus. It is probably still a compromise worth to be made because it prevents your strokes from being skewed. Find out your tablet's resolution by running: ``` $ xsetwacom get *stylus* Area ``` #### Reducing the drawing area height Run: ``` $ xsetwacom set *stylus* Area 0 0 *tablet_width* *height* ``` where: * *tablet_width* is the width of the tablet resolution, and * *height* is `tablet_width * screen_height / screen_width` The tablet resolution can be reset back to the default using: ``` $ xsetwacom set *stylus* ResetArea ``` #### Reducing the screen area width Run: ``` $ xsetwacom set *stylus* MapToOutput *WIDTH*x*HEIGHT*+0+0 ``` where: * *WIDTH* is `screen_height * tablet_width / tablet_height`, and * *HEIGHT* is the height of the screen resolution ### Using kcm-wacomtablet The KDE configuration module [kcm-wacomtablet](https://www.archlinux.org/packages/?name=kcm-wacomtablet) (or if you're on Plasma 5, [kcm-wacomtablet-frameworks-git](https://aur.archlinux.org/packages/kcm-wacomtablet-frameworks-git/)) supports easy configuration of the tablet through a graphical user interface, allowing for different profiles and proper hotplugging support. It will auto-detect the type of your tablet, and load your configuration profile automatically when the tablet is plugged in. ## Application-specific configuration ### Blender To enable pad buttons and extra pen buttons in [Blender](/index.php/Blender "Blender"), you can create a xsetwacom wrapper to temporarily remap buttons for your blender session. Provided example (for Bamboo fun) adapted to **Sculpt** mode: [blender_sculpt.sh](http://pastebin.archlinux.fr/1887946) It remaps * Left tablet buttons to **Shift** and **Control** *(pan/tilt/zoom/smooth/invert)* * Right tablet buttons to **F** *(brush size/strenght)* and **Control-z** *(undo)* * Top pen button ton **m** *(mask control)* ### GIMP To enable proper usage, and pressure sensitive painting in [GIMP](/index.php/GIMP "GIMP"), just go to *Edit > Input Devices*. Now for each of your *eraser*, *stylus*, and *cursor* **devices**, set the **mode** to *Screen*, and remember to save. * Please take note that if present, the *pad* **device** should be kept disabled as I do not think GIMP supports such things. Alternatively, to use such features of your tablet you should map them to keyboard commands with a program such as [Wacom ExpressKeys](http://hem.bredband.net/devel/wacom/). * You should also take note that the tool selected for the *stylus* is independent to that of the *eraser*. This can actually be quite handy, as you can have the *eraser* set to be used as any tool you like. For more information checkout the *Setting up GIMP* section of [GIMP Talk - Community - Install Guide: Getting Wacom Drawing Tablets To Work In Gimp](http://www.gimptalk.com/forum/topic.php?t=17992&start=1). If the above was not enough, you may want to try setting up the tablet's stylus (and eraser) as a second mouse pointer (separating it from your mouse) by using the `xinput create-master` and `xinput reattach` commands. It can help when GIMP does not start painting even if the stylus touches the tablet. ### Inkscape Pressure sensitivity in [Inkscape](/index.php/Inkscape "Inkscape") is enabled the same way as in GIMP. Go to *Edit > Input Devices...*. Now for each of your *eraser*, *stylus*, and *cursor* **devices**, set the **mode** to *Screen*, and remember to save. ### Krita If your tablet does not draw in Krita (clicks/pressure are not registered) but works in the brush selection dialog which has a small test area, try putting Krita in full-screen or canvas-only mode. Krita only requires that Qt is able to use your tablet to function properly. If your tablet is not working in Krita, then make sure to check it is working in Qt first. The effect of tablet pressure can then be tweaked in the painttop configuration, for example by selecting opacity, then selecting pressure from the drop down and adjusting the curve to your preference. ### VirtualBox First, make sure that your tablet works well under Arch. Then, download and install the last driver from [Wacom website](http://www.wacom.com/downloads/drivers.php) on the guest OS. Shutdown the virtual machine, go to **Settings > USB**. Select **Add Filter From Device** and select your tablet (e.g. WACOM CTE-440-U V4.0-3 [0403]). Select **Edit Filter**, and change the last item **Remote** to **Any**. ## Troubleshooting Newer tablets' drivers might not be in the kernel yet, and additional manipulations might be needed. A notable example is the newer Intuos line of tablets (Draw/Comic/Photo). ### Unknown device_type If your tablet does not get recognized by `xsetwacom` and `dmesg` complains about an unknown device_type, then you need to install a patched version of input-wacom. Download and install the for-4.4 branch from [SourceForge](http://sourceforge.net/p/linuxwacom/input-wacom/ci/jiri/for-4.4/~/tarball). Your device should be recognized after you run ``` # rmmod wacom # insmod /lib/modules/YOUR_KERNEL/kernel/drivers/hid/wacom.ko.gz ``` ### Tablet recognized but xsetwacom and similar tools do not display it Your logs indicate that the correct driver is selected, and the tablet works. However, when running `xsetwacom list devices` or use similar tools that depend on the correct driver, you get an empty list. A reason might be the execution order of your xorg configuration. `/usr/share/X11/xorg.conf.d` gets executed first, then `/etc/X11/xorg.conf.d`. The package [xf86-input-wacom](https://www.archlinux.org/packages/?name=xf86-input-wacom) contains the file `/usr/share/X11/xorg.conf.d/70-wacom.conf`. If there is a catchall for tablets, executed after this file, the previously selected `wacom` driver will be overwritten with a generic one that does not work with xsetwacom et. al. To make sure, check the rules contained in the files executed after `/usr/share/X11/xorg.conf.d/70-wacom.conf` for anything that looks like graphics tablets. ## References * [Linux Wacom Project Wiki](https://github.com/linuxwacom/input-wacom/wiki) * [GIMP Talk - Community - Install Guide: Getting Wacom Drawing Tablets To Work In Gimp](http://www.gimptalk.com/forum/topic.php?t=17992&start=1) * [Ubuntu Help: Wacom](https://help.ubuntu.com/community/Wacom) * [Ubuntu Forums - Install a LinuxWacom Kernel Driver for Tablet PC's](http://ubuntuforums.org/showthread.php?t=1038949)
