[Bug 429942] Re: ASUS 1101HA brightness hotkeys don't work, generate ACPI errors
The above post helped me to set backlight dimmer on my Asus EEEPC 1101HA, running ubuntu 12.04.
But the commands have to be changed somewhat to actually change the file /sys/class/backlight/psb-bl/brightness
2) chmod 666 /sys/class/backlight/psb-bl/brightness
to give yourself permission to read/write (711 actually only gives execute permission)
3) Using a text editor (I use vi) gives Fsync errors (/sys is not a normal filesystem), so use the shell to write to the "file" instead:
First choose the number, for example 50. The command is:
echo 50 >| /sys/class/backlight/psb-bl/brightness
4) done.

Title:
ASUS 1101HA brightness hotkeys don't work, generate ACPI errors
Status in “acpi-support” package in Ubuntu:
Fix Released
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
Hi,
some of the hotkeys don't work correct.
I'm using Ubuntu UNR 9.04. The keyboard layout is set to Asus-Laptop (the installer set it to Generic 105 (itel) I think) but ther is no change.
Correct are:
Fn+F1: Hibranate
Fn+F7: disable display backlight
Fn+F10,F11,F12: audio volume keys
Fn+Space: wake-up
Fn+Arrowkeys: Page up/down, end, pos1
Fn+Insert: Numlock
Wrong is:
Fn+F8: it should enable or disable the VGA output ... instead it increases audio volume (just like Fn+F12)
Nonefunctional are:
Fn+F2: Disable Wlan/Bluetooth
Fn+F3: Disable touthpad
Fn+F4: toggle fullscreen
Fn+F6,F7: Display brightnes/backlight control
Fn+F9: open taskmanager (in MS Win)
also nonefunctional is the extra buttom on the left above the keybord
to disable touchpad.
--Fn+F2--Wlan--
for this key I get in 'xev':
xev | grep keycode
request MappingKeyboard, first_keycode 8, count 247
state 0x0, keycode 246 (keysym 0x1008ff95, XF86WLAN), same_screen YES,
state 0x0, keycode 246 (keysym 0x1008ff95, XF86WLAN), same_screen YES,
and acpi_listen:
hotkey ATKD 00000010 00000024
----------------------
--Fn+F3/additional Touchpadkey--
nothing in xev but in acpi_listen:

--Fn+F4-toggle Fulscreen--
nothing in xev
acpi_listen:

----------------------------------
--Fn+F5-decreas display-brightness/backlight--
nothing in xev and acpi_listen, but these messages in dmesg:

---------------------------------
--Fn+F6-increas display-brightness/backlight--
nothing in xev and acpi_listen, but these messages in dmesg:

--------------------------------

xev | grep keycode

request MappingKeyboard, first_keycode 8, count 248
request MappingKeyboard, first_keycode 8, count 247
sudo acpi_listen

-----------------------------
--Fn+F9-Taskmanager--
xev | grep keycode
request MappingKeyboard, first_keycode 8, count 247
state 0x0, keycode 156 (keysym 0x1008ff41, XF86Launch1), same_screen YES,
state 0x0, keycode 156 (keysym 0x1008ff41, XF86Launch1), same_screen YES,
sudo acpi_listen
hotkey ATKD 00000012 00000007
------------------------------
That's what I got. If you need anything else then tell me.
