[[Category:ASUS]]
This page contains instructions, tips, pointers, and links for installing and configuring Arch Linux on the ASUS G55VW ROG Laptop

== Bootloader ==
=== Boot on usb ===
Press {{ic|Escape}} to get the boot menu. If usb bootable device is not listed, enter configuration menu and directly press {{ic|F10}} to save. Press {{ic|Escape}} again on reboot : this time USB bootable device should appears in the menu.

=== Set up UEFI boot ===
{{Note|It is recommended to read the [[UEFI]], [[GPT]] and [[UEFI Bootloaders]] pages before following those instructions.}}

It is possible to use [[UEFI_Bootloaders#Setting_up_EFISTUB|UEFISTUB]]{{Broken section link}} in-kernel bootloader, if you wish. We present here the [[GRUB2]] way. We assume {{ic|x86_64}} version of Arch Linux.
{{warning| UX31A firmware is {{ic|x86_64}}, so it makes it compulsory to use {{ic|x86_64}} kernel to be able to dual boot with Windows in UEFI mode }}

In the original partition setup:

first partition: UEFI boot fat32 partition, should be mounted on {{ic|/boot/efi}} in Arch.

second partition: [[GUID Partition Table]]

Step 0 (optional): install [https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2/ShellBinPkg/UefiShell/X64/Shell.efi x86_64 UEFI Shell 2.0 (Beta)]:

See [[UEFI#UEFI Shell]]. Can be useful during install, especially it allows to manually boot using [[UEFI_Bootloaders#Setting_up_EFISTUB|UEFISTUB]]{{Broken section link}}.

Step 1: granted you can boot into your install through install disk, grub1 or via a liveusb and a chroot:
# pacman -S grub-efi-x86_64
Follow [[GRUB2#UEFI systems]].

Optional: add some power optimisation kernel parameters. In {{ic|/etc/default/grub}} file:
GRUB_CMDLINE_LINUX_DEFAULT="quiet add_efi_memmap i915.i915_enable_rc6=1 drm.vblankoffdelay=1 i915.semaphores=1"
{{Note| concerning kernel parameter {{ic| pcie_aspm=force}}, I'm unsure: Ubuntu wiki recommends it, but UX31E Arch wiki says it should not be used.}}

Reinstall grub2 :
grub-mkconfig -o /path/to/grub.cfg

Step 2: it is not yet possible to finish install by [[UEFI#Create_GRUB2_entry_in_the_Firmware_Boot_Manager|creating GRUB2 entry in the Firmware Boot Manager]]{{Broken section link}} since it is required to boot in UEFI mode to be able to use [[Unified_Extensible_Firmware_Interface#efibootmgr|efibootmgr]]. The tricks is to do:

# cp /boot/efi/EFI/arch_grub/grubx64.efi /boot/efi/shellx64.efi

{{Note| temporary move {{ic|shellx64.efi}} if necessary }}

# reboot

Press {{ic|F2}} on reboot and choose "Launch EFI shell from filesystem device". It should trigger grub2 and boot into arch if grub2 is correctly set up. You should now be able to [[Unified_Extensible_Firmware_Interface#efibootmgr|use efibootmgr to add grub entry to firmware]].

== Graphics Drivers ==

See [[NVIDIA]].

== Screen Backlight ==

Using the nvidia drivers provided in the extra repo screen the backlight-adjust keys({{ic|Fn+F5}}, {{ic|Fn+F6}}) do not work. To get around this, you need to grab ({aur|nvidiabl-git}). Once you have installed that package, you can map your keys to the script.

== Other Keys ==

It is also possible to use [[Dynamic Kernel Module Support]] (DKMS) (package in community), to avoid compiling the whole kernel:

1 get the archive at http://ubuntuforums.org/showthread.php?p=12054636#post12054636 (ubuntu forums account + minimum of 50 posts required) or http://markmail.org/message/idvl6s27r26xzorb (no account required)
{{note | there is perhaps more suitable place to get the asus-wmi kernel module sources, the patch and the dkms conf file}}
2 extract the archive, and then extract the .deb and get the sources inside (asus-wmi.c is already patched with above patch):
# cp -a usr/src/asus-wmi-0.2 /usr/src/
# cd /usr/src/
# dkms add -m asus-wmi -v 0.2
# dkms built -m asus-wmi -v 0.2 -k 3.4.6-1-ARCH
# dkms status
# dkms install -m asus-wmi -v 0.2 -k 3.4.6-1-ARCH
# dkms status

replace {{ic|3.4.6-1-ARCH}} by your output for {{ic|uname -r}}

3 There is still a problem since dkms doesn't gzip the kernel module and archlinux does (see {{ic|$ modinfo asus-wmi}}):
# cd /lib/modules/3.4.6-1-ARCH/kernel/drivers/platform/x86/
# mv asus-wmi.ko.gz asus-wmi.ko.gz.save
# gzip asus-wmi.ko
{{note | there is probably a cleaner way to do that with dkms}}
4 After reboot, {{ic|xev}} should display events for {{ic|Fn}} keys. And keyboard backlight can be trigger by:
# echo 0 >> /sys/class/leds/asus\:\:kbd_backlight/brightness
# echo 3 >> /sys/class/leds/asus\:\:kbd_backlight/brightness

=== keyboard backlight script ===
In the same style that for screen backlight. As root, create the file {{ic|/usr/local/share/kbd_backlight}}:
#!/bin/bash

path="/sys/class/leds/asus::kbd_backlight"
#path="/sys/class/leds/asus\:\:kbd_backlight"

# max should be 3
max=$(cat ${path}/max_brightness)
# step: represent the difference between previous and next brightness
step=1
previous=$(cat ${path}/brightness)

function commit {
if [[ $1 = [0-9]* ]]
then
if <nowiki>[[ $1 -gt $max ]]</nowiki>
then
next=$max
elif <nowiki>[[ $1 -lt 0 ]]</nowiki>
then
next=0
else
next=$1
fi
echo $next >> ${path}/brightness
exit 0
else
exit 1
fi
}

case "$1" in
up)
commit $(($previous + $step))
;;
down)
commit $(($previous - $step))
;;
max)
commit $max
;;
on)
$0 max
;;
off)
commit 0
;;
show)
echo $previous
;;
night)
commit 1
;;
allowusers)
# Allow members of users group to change brightness
sudo chgrp users ${path}/brightness
sudo chmod g+w ${path}/brightness
;;
disallowusers)
# Allow members of users group to change brightness
sudo chgrp root ${path}/brightness
sudo chmod g-w ${path}/brightness
;;
*)
commit $1
esac

exit 0

Allow file to be executed :
# chmod +x /usr/local/share/kbd_backlight

Allow users to change brightness at each boot :
# echo "/bin/bash /usr/local/share/kbd_backlight allowusers" >> /etc/rc.local

Adding to {{ic|.zshrc}} or {{ic|.bashrc}} :
alias -g "kbd_backlight"="/bin/bash /usr/local/share/kbd_backlight"
allows to easy toggle backlight in terminal :
$ kbd_backlight up
$ kbd_backlight down
$ kbd_backlight max
$ kbd_backlight off
$ kbd_backlight night
$ kbd_backlight 2
$ kbd_backlight show

And finally, add some convenient keyboard shortcuts [[Extra keyboard keys in Xorg|by the method of your choice]].
