Acer TimelineX

Hardware is a 4820TG/5820TG, but should be similar for all these laptops.

Installation

There is a quirk if you want to install archlinux, you need to connect via wireless as ethernet hardware is supported only by linux 2.6.34+. Follow beginners' guide for the rest.

Xorg

You need ati and i915 xorg drivers.

pacman -S xf86-video-ati xf86-video-intel

With Xorg you don't need hal anymore, and configuration can be done exclusiuvely within the xorg.conf.d directory

Experimental Ati drivers

These drivers are unstable. If you are not an experienced linux user please don't try this drivers, they would eat your hamster.

2D/X11

There is a branch in mesa that adds 2D and Xv support for ati evergreen cards. PKG in AUR is called xf86-video-evergreen-git

yaourt -S xf86-video-ati-git

Notice:Be careful. It still hangs at X11 startup for me.

3D

Initial support for evergreen is in git/master branch. It is enough to install mesa-git.

yaourt -S mesa-git

Touchpad

Touchpad is a synaptics so you need its driver:

pacman -S xf86-input-synaptics

Then add to /etc/X11/xorg.conf.d a new file (name it 20-synaptics.conf)

Section "InputClass"
 Identifier "touchpad"
 Driver "synaptics"
 MatchIsTouchpad "on"
 Option "SHMConfig" "on"
 Option "TapButton1" "1"
 Option "TapButton2" "2"
 Option "TapButton3" "3"
 Option "VertEdgeScroll" "on"
 Option "VertTwoFingerScroll" "on"
 Option "HorizEdgeScroll" "on"
 Option "HorizTwoFingerScroll" "on"
 Option "CircularScrolling" "on"
 Option "CircScrollTrigger" "2"
 Option "EmulateTwoFingerMinZ" "0"
EndSection

For more info, check Touchpad_Synaptics

Keyboard

Add a new file in xorg.conf.d (name it 20-keymap.conf)

Section "InputClass"
        Identifier "Acer Keyboard"
        MatchIsKeyboard "on"
        MatchDevicePath "/dev/input/event*"
        Option                 "XkbLayout" "it"
        Option                 "XkbModel" "acer_laptop"
        Driver "evdev"
EndSection

Replace it with your keymap.

Switchable Graphics

Switching cards works. A restart of Xorg is required to switch.

#enable ati
echo DDIS > /sys/kernel/debug/vgaswitcheroo/switch
#enable intel
echo DIGD > /sys/kernel/debug/vgaswitcheroo/switch
#power off unused card
echo OFF > /sys/kernel/debug/vgaswitcheroo/switch
#Status
cat /sys/kernel/debug/vgaswitcheroo/switch

ACPI

ACPI works with BIOS v1.18 and higher.

Laptop Mode Tools

Install laptop-mode-tools

pacman -S laptop-mode-tools

You need to enable these modules in /etc/laptop-mode/conf.d

auto-hibernate.conf Hibernate when battery level becomes critical

cpufreq.conf Adjust CPU speed

Add acpi_cpufreq, cpufreq_ondemand and cpufreq_powersave to modules in rc.conf

dpms-standby.conf Turn off screen when not needed

ethernet.conf Turn off ethernet when on battery

intel-hda-powersave.conf Turn on powersaving for audio chip

intel-sata-powermgmt.conf Powersave for hard disk

lcd-brightness.conf Change brightness when on battery

The file is called /proc/acpi/video/GFX0/DD02/brightness and acceptable values are 10..100 with a step of 10

sched-mc-power-savings.conf Additional CPU powersave features

sched-smt-power-savings.conf Additional CPU powersave features

usb-autosuspend.conf Suspend unused USB devices

video-out.conf Disable video out on battery

wireless-power.conf Powersaving for atheros chip

Hardware

Bluetooth

Works out of the box. On some machines cannot turn on because of Fn+F3 switching only WLAN. Fixed DSDT table seems to solve the problem.

Wifi

Works out of the box and supports injection and ap mode.

TimelineX 5820

Wifi driver needs to be installed. Open-source brcm80211 driver causes kernel panics; proprietary broadcom-wl driver works fine.

TimelineX 4820TG

Wifi driver does not work by default. You need to install broadcom-wl and b43-firmware.

# aurget --deps -Sy broadcom-wl
# aurget --deps -Sy b43-firmware

Once you are done with driver and firmware installation, you need add following in the modules in rc.conf and reboot:

MODULES=([...] !b43 !ssb !lib80211 lib80211_crypt_tkip wl)

Once rebooted, you can confirm the working of the driver by following commands

# ifconfig -a
# ifconfig eth1 up
# iwconfig eth1
# iwlist eth1 scan

For more information, check Broadcom_BCM43XX

Camera

Works out of the box.

Card Reader

Works out of the box, tested with a SD card.
