The backlight control, keyboard keymap, and sound sections have been verified on Gentoo Linux. Minor modifications to these instructions may have to be made for your distribution. (These entries were made by Chris Snow)
The default light level is set to zero. This results in the screen brightness being very dim. You may set the backlight level (ls_level) anywhere from 0 (least bright) to 15 (brightest).
$ sudo echo 1 > /sys/devices/platform/asus-laptop/ls_switch # make sure the switch is 'on'. $ sudo echo 15 > /sys/devices/platform/asus-laptop/ls_level # set the backlight brightness.
I added the above command, minus
sudo, to a startup script so that the screen is set to the brightest level on boot.
Generally speaking, the keyboard works without issue. Two caveats: Most “Fn” keys combinations do not work; Default keymaps for Shift-PgUp/Shift-PgDn do not work to control the console scrollback buffer.
There are several ways to correct the keymaps to allow for proper control of the console scrollback buffer, I chose to do the following:
$ sudo sed -i 's/shift keycode 104/shift keycode 73/g' /usr/share/keymaps/i386/include/linux-keys-bare.inc $ sudo sed -i 's/shift keycode 109/shift keycode 81/g' /usr/share/keymaps/i386/include/linux-keys-bare.inc $ sudo /etc/init.d/keymaps restart
The laptop speakers will not mute when external speakers or heaphones are plugged in. A quick fix for this is to add the following line to
/etc/modprobe.d/alsa (create the file if it does not exist):
options snd-hda-intel model=haier-w66
