Hardware is a 4820TG/5820TG, but should be similar for all these laptops. | **Device** | **Status** | **Modules** | | Intel | **Working** | xf86-video-intel | | Ati | **Partially Working** | xf86-video-ati | | Ati | **Working** | fglrx | | Bluetooth | **Working** | bluetooth | | Ethernet | **Working** | atl1c (2.6.36) | | Wireless | **Working** | ath9k / wl | | Wireless | **Working** | bcm4357 / wl | | Audio | **Working** | snd_hda_intel | | Camera | **Working** | uvcvideo | | Card Reader | **Working** | | Function Keys | **Working** | ## Contents * [1 ACPI](#ACPI) * [2 Hardware](#Hardware) * [2.1 Bluetooth](#Bluetooth) * [2.2 Wi-Fi](#Wi-Fi) * [2.2.1 TimelineX 5820](#TimelineX_5820) * [2.2.2 TimelineX 4820TG](#TimelineX_4820TG) * [2.2.3 TimelineX 3820TG](#TimelineX_3820TG) * [2.3 Camera](#Camera) * [2.4 Card Reader](#Card_Reader) * [2.5 Display brightness control](#Display_brightness_control) * [3 Info](#Info) * [3.1 lspci](#lspci) * [3.2 lspci - TimelineX 4820TG (with Broadcom 4357 wifi)](#lspci_-_TimelineX_4820TG_.28with_Broadcom_4357_wifi.29) * [3.3 lspci - TimelineX 3820TG-5464G50iks](#lspci_-_TimelineX_3820TG-5464G50iks) * [4 Issues](#Issues) * [5 Links](#Links) ## ACPI ACPI works with BIOS v1.18 and higher. [BIOS v1.19 for 4820tg](http://global-download.acer.com/GDFiles/BIOS/BIOS/BIOS_Acer_1.19_A_A.zip?acerid=634217844152767304&Step1=Notebook&Step2=Aspire&Step3=Aspire%204820TG&OS=722&LC=en&BC=Acer&SC=PA_6) [BIOS v1.19 for 3820tg](http://global-download.acer.com/GDFiles/BIOS/BIOS/BIOS_Acer_1.19_A_A.zip?acerid=634308246297660203&Step1=Notebook&Step2=Aspire&Step3=Aspire%203820TG&OS=722&LC=en&BC=Acer&SC=PA_6) If you do not have Windows installed, you can flash with a [FreeDOS thumb drive](http://www.freedos.org/). ## Hardware ### Bluetooth Works out of the box. On some machines, Bluetooth cannot turn on because of `Fn`+`F3` switching only WLAN. [Fixed DSDT table](http://ubuntuforums.org/showpost.php?p=10021228&postcount=183) seems to solve the problem. On the 3820TG, Bluetooth might not work even if `Fn`+`F3` is used to turn it on. (Symptoms include "usb disconnect" messages in dmesg, and the adapter not showing up in *hcitool dev*.) In this case, copying `/lib/firmware/ath3k-2.fw` to `/lib/firmware/ath3k-1.fw` helps, see [this mailing list thread](http://www.mail-archive.com/ubuntu-bugs@lists.ubuntu.com/msg2579867.html). If it does not work for you, please change this note! For some models of 4820TG, Bluetooth can be turned on with acer_wmi driver. To check that the driver is installed: ``` lsmod | grep acer_wmi ``` To check bluetooth state (1 is on, 0 is off): `cat /sys/devices/platform/acer-wmi/rfkill/rfkill2/{name,state}` ``` acer-bluetooth 0 ``` To turn on bluetooth: ``` echo -n 1 > /sys/devices/platform/acer-wmi/rfkill/rfkill2/state ``` ### Wi-Fi Works out of the box and supports injection and AP mode. #### TimelineX 5820 Wi-Fi driver needs to be installed. Open source [brcm80211](/index.php/Broadcom_wireless#brcmsmac.2Fbrcmfmac "Broadcom wireless") driver causes kernel panics; the proprietary [broadcom-wl](/index.php/Broadcom_wireless#broadcom-wl "Broadcom wireless") driver works fine. #### TimelineX 4820TG Wi-Fi driver does not work by default. You need to install [broadcom-wl](https://www.archlinux.org/packages/?name=broadcom-wl) and [b43-firmware](https://aur.archlinux.org/packages/b43-firmware/). See [Broadcom wireless](/index.php/Broadcom_wireless "Broadcom wireless") for details. #### TimelineX 3820TG Works out of the box, `lspci` lists the chip as ``` 05:00.0 Network controller: Atheros Communications Inc. AR9287 Wireless Network Adapter (rev 01) ``` ### Camera Works out of the box. ### Card Reader Works out of the box, tested with a SD card. ### Display brightness control Sometimes brightness control for integrated card does not work (at least with the 2.6.36.2-1 kernel). You may add `acpi_osi=Linux` to the kernel line in the [GRUB](/index.php/GRUB "GRUB") config to fix this. ## Info ### lspci ``` 00:00.0 Host bridge: Intel Corporation Core Processor DRAM Controller (rev 12) 00:01.0 PCI bridge: Intel Corporation Core Processor PCI Express x16 Root Port (rev ff) 00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 12) 00:16.0 Communication controller: Intel Corporation 5 Series/3400 Series Chipset HECI Controller (rev 06) 00:1a.0 USB Controller: Intel Corporation 5 Series/3400 Series Chipset USB2 Enhanced Host Controller (rev 05) 00:1b.0 Audio device: Intel Corporation 5 Series/3400 Series Chipset High Definition Audio (rev 05) 00:1c.0 PCI bridge: Intel Corporation 5 Series/3400 Series Chipset PCI Express Root Port 1 (rev 05) 00:1c.5 PCI bridge: Intel Corporation 5 Series/3400 Series Chipset PCI Express Root Port 6 (rev 05) 00:1d.0 USB Controller: Intel Corporation 5 Series/3400 Series Chipset USB2 Enhanced Host Controller (rev 05) 00:1e.0 PCI bridge: Intel Corporation 82801 Mobile PCI Bridge (rev a5) 00:1f.0 ISA bridge: Intel Corporation Mobile 5 Series Chipset LPC Interface Controller (rev 05) 00:1f.2 SATA controller: Intel Corporation 5 Series/3400 Series Chipset 4 port SATA AHCI Controller (rev 05) 00:1f.3 SMBus: Intel Corporation 5 Series/3400 Series Chipset SMBus Controller (rev 05) 00:1f.6 Signal processing controller: Intel Corporation 5 Series/3400 Series Chipset Thermal Subsystem (rev 05) 01:00.0 VGA compatible controller: ATI Technologies Inc Device 68e0 (rev ff) 01:00.1 Audio device: ATI Technologies Inc Device aa68 (rev ff) 02:00.0 Ethernet controller: Atheros Communications AR8151 v1.0 Gigabit Ethernet (rev c0) 03:00.0 Network controller: Atheros Communications Inc.
