By visiting the downloads section (T470) an ISO can be downloaded and burned to disk which will perform the update [from Lenovo](http://pcsupport.lenovo.com/gb/en/products/laptops-and-netbooks/thinkpad-t-series-laptops/thinkpad-t470/downloads). Or [extracted and copied on a USB Stick](http://www.thinkwiki.org/wiki/BIOS_Upgrade#Booting_from_a_USB_Flash_drive). ## Kernel and hardware support [Hardware video acceleration](/index.php/Hardware_video_acceleration "Hardware video acceleration") with Kaby Lake seems to work fine via va-api. As noted in [Intel graphics](/index.php/Intel_graphics "Intel graphics"), the [xf86-video-intel](https://www.archlinux.org/packages/?name=xf86-video-intel) driver seems to cause more issue than the builtin `modesetting` Xorg driver. Works fine without the intel driver (on a Skylake configuration). suspend-resume results in the fan holding at 100% without ever spinning down. This is being tracked on the [kernel bugtracker](https://bugzilla.kernel.org/show_bug.cgi?id=196975). The issue [seems to be resolved](https://bugzilla.kernel.org/show_bug.cgi?id=196975#c54) by BIOS 1.43. ### Fingerprint reader As of writing this, the fingerprint reader is still under [prototype development](https://github.com/nmikhailov/Validity90), but looks like working fine on the T470. To get the sensor working, it first must be initialized with data. This currently only works with Windows. So if you had used the reader before installing Arch, this should work fine. Otherwise install a Windows version in a virtualbox, connect the Validity Sensor over USB(USB 2.0), install the drivers and use it a few times. As soon as this step is completed, the sensor can be used under Linux. Check out [Validity90 prototype](https://github.com/nmikhailov/Validity90/tree/master/prototype), build it and check if the sensor is working. Install [fprintd](https://www.archlinux.org/packages/?name=fprintd), [libfprint-vfs0097-git](https://aur.archlinux.org/packages/libfprint-vfs0097-git/) and for testing [fprint_demo](https://aur.archlinux.org/packages/fprint_demo/). You can now enroll your fingers. fprintd and fprint_demo might have be started with superuser privileges. After setting up the fingerprint sensor is complete, one can use it to login or authenticate for `sudo` or `su`(To use this, launch fprintd_enroll prior as root). For login edit `/etc/pam.d/login` Add the following and comment out the other entrys ``` auth required pam_env.so auth sufficient pam_fprintd.so auth sufficient pam_unix.so try_first_pass likeauth nullok auth required pam_deny.so ``` Do the same for sudo with `/etc/pam.d/sudo` or su with `/etc/pam.d/su` For more information visit [libfprint](https://github.com/3v1n0/libfprint) and adapt for the vfs0097 package. ### Screen backlight Without the `intel` driver ([xf86-video-intel](https://www.archlinux.org/packages/?name=xf86-video-intel)), neither `xbacklight` or `xrandr` brightness control are working. It is possible that, with the good `acpi_*` kernel parameters, the backlight related keys do their job. Other workaround exists, such as described [on this post](https://bbs.archlinux.org/viewtopic.php?pid=1449243#p1449243) or in the wiki [acpid#Enabling backlight control](/index.php/Acpid#Enabling_backlight_control "Acpid"). Using the [acpilight](https://aur.archlinux.org/packages/acpilight/) package as a `xbacklight` replacement works well. You can also check [this repository](https://lab.knightsofnii.com/kristaba/tpacpi-backlight)] as a base to add the ACPI rules to call `xbacklight` when backlight keys are pressed. **Note:** The [acpilight](https://aur.archlinux.org/packages/acpilight/) package is known to allow controlling the ThinkPad keyboard backlight. Similar ACPI rules should allow to toggle it when the keyboard backlight key is pressed. ### Thunderbolt 3 With the latest kernel (4.12.12 as of writing), the *Alpine Ridge* thunderbolt 3 controller is recognized without any additional configuration. Using a generic thunderbolt 3 to HDMI + USB3 hub works out of the box (the HDMI output is recognized by xrandr as DP-1 output). ### UEFI boot After configuring the BIOS setup to allow UEFI boot (either *UEFI only* or *both*), it works flawlessly. **Note:** I was unable to boot with a GPT + BIOS configuration, and therefore switch to GPT + EFI. However, until another confirmation, it is quite probable that was caused by some bad configuration from my side. ### Special buttons Some special buttons are not supported by X server due to keycode number limit. | Key combination | Scancode | Keycode | | `Fn+F11` | `0x49` | `374` `KEY_KEYBOARD` | | `Fn+F12` | `0x45` | `364` `KEY_FAVORITES` | You can remap unsupported keys using [udev hwdb](/index.php/Map_scancodes_to_keycodes "Map scancodes to keycodes"): `/etc/udev/hwdb.d/90-thinkpad-keyboard.hwdb` ``` evdev:name:ThinkPad Extra Buttons:dmi:bvn*:bvr*:bd*:svnLENOVO*:pn* KEYBOARD_KEY_45=prog1 KEYBOARD_KEY_49=prog2 ``` Update hwdb after editing the rule. ``` # udevadm hwdb --update # udevadm trigger --sysname-match="event*" ``` ## PCI and USB devices ### T470 model 20HD Kernel '4.10.13-1-ARCH' #### lspci ``` 00:00.0 Host bridge: Intel Corporation Device 5904 (rev 02) 00:02.0 VGA compatible controller: Intel Corporation Device 5916 (rev 02) 00:14.0 USB controller: Intel Corporation Sunrise Point-LP USB 3.0 xHCI Controller (rev 21) 00:14.2 Signal processing controller: Intel Corporation Sunrise Point-LP Thermal subsystem (rev 21) 00:16.0 Communication controller: Intel Corporation Sunrise Point-LP CSME HECI #1 (rev 21) 00:1c.0 PCI bridge: Intel Corporation Device 9d10 (rev f1) 00:1c.6 PCI bridge: Intel Corporation Sunrise Point-LP PCI Express Root Port #7 (rev f1) 00:1d.0 PCI bridge: Intel Corporation Sunrise Point-LP PCI Express Root Port #9 (rev f1) 00:1d.2 PCI bridge: Intel Corporation Device 9d1a (rev f1) 00:1f.0 ISA bridge: Intel Corporation Device 9d58 (rev 21) 00:1f.2 Memory controller: Intel Corporation Sunrise Point-LP PMC (rev 21) 00:1f.3 Audio device: Intel Corporation Device 9d71 (rev 21) 00:1f.4 SMBus: Intel Corporation Sunrise Point-LP SMBus (rev 21) 00:1f.6 Ethernet controller: Intel Corporation Ethernet Connection (4) I219-V (rev 21) 04:00.0 Network controller: Intel Corporation Device 24fd (rev 78) 3e:00.0 Non-Volatile memory controller: Samsung Electronics Co Ltd Device a804 ``` #### lsusb ``` Bus 002 Device 007: ID 0bda:0316 Realtek Semiconductor Corp.
