ASUS 1101HA brightness hotkeys don't work, generate ACPI errors

So ... I've done some research:

It seems that only user with the german version of the AUSUS EEE 1101HA have this problem.
Changing the keyboard-layout to any english/us one does nothing.

And eee-applet, eee-control don't work for this model.

Hi again ....

so the wireless-switch works if you add "rfkill_input" to your "/etc/modules" ...

btw: like in bug #356335 eeepc-acpi-scripts is uninstallable. So I tried to load the eeepc_laptop module but this changes nothing (see bug #328989).

Still not working:
Taskmanager-Key -> sends Xev thats ok for me ...
Touchpad-Key(s) -> I don't really need them ...
Toggle-Fullscreen -> in UNR everything is fullscreen ^^

Display-Output and Brightness-Controll are verry important I think, the first one does something wrong and the last one has ACPI errors. So I think the BUG is in ACPI ... or wherever this Key-Events are maped.

Hi, I managed to edit / hack a working version of eee-control 0.9.4, and it doesn't change anything, I still have the same errors as you with the FN keys. I have a portuguese keyboard on my 1101HA.

The problem still exists in karmic beta (kernel 2.6.31-14-generic), the only exception is the wireless button which is working and fn+f8 doesn't change volume, but i couldn't test if it actually toggles on/off the vga out.
Kernel problems still exist for touch-pad keys not translating the ACPI event to an input event.

>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.

You shouldn't do that. In recent Linux distributions, the keyboard layout should be set to Evdev-managed keyboard.

badook, you mention that there are problems in karmic, but could you please also explicitly confirm that you have the same model?

There is no rfkill_input module in karmic; this should now work by default, yes.

Fn+F8/VGA - This key is trapped by gnome-settings-daemon, so you would never see output in xev anyway. But you should be able to run 'lshal -m' to get output like this:

$ lshal -m

Do the brightness keys still cause ACPI errors in karmic?

Hi again, after I get Karmic to work on my eee1101ha .... the news ...

so Fn+F8 works just well ...

And the brightnesskey still causes ACPI errors:

FN+F5:
[ 3771.188756] ACPI Exception: AE_AML_NO_RETURN_VALUE, Missing or null operand 20090521 dsutils-646

btw .... the backlightsettings from the gnome-powermanagement work fine .... also do xbacklight ....

Thanks, it sounds like the only outstanding issue is the ACPI error from the brightness hotkeys. Opening a bug on the linux package for this.

I don't understand: has anybody fixed it? I don't think so, I still have problems with Fn+F5/F6. I think now it's obvious, but also "italian" eeepc 1101HA has this problem.

I don't think this can be regarded as fixed, too - I am still having trouble with the following keys:
Fn + F3 for disabling the touchpad does not work
Fn + F4 does nothing
Fn + F5 decreasing brightness does not work
Fn + F6 increasing brightness does not work
Fn + F7 does nothing
Fn + F8 does nothing
Fn + F9 does nothing
The Fn Button also should activate Numpad - funktions on the Keys 7, 8, 9, U, I, O, J, K, L and M.

A Button on the top left of the keyboard to disable the touchpad is also nonfunctional, as well as the multitouch - function of the touchpad itself.

I'll gladly submit any information that could be helpful to solve the problem - just give me a hint which files you could use.

Please file a new bug report, with information about what keys are not functioning correctly and what you expect them to do.

with the new version of eee-controle (http://greg.geekmind.org/eee-control/deb/) the brightness control works fine. I haven't tested any other functions.

Hi Spock112,

Please be sure to confirm this issue exists with the latest development release of Ubuntu. ISO CD images are available from http://cdimage.ubuntu.com/releases/lucid . If the issue remains, please run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 429942

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

In my ASUS UL30A I have the same issue, the hotkeys are the as the computer of the bug description. When I start to monitoring the devicelist with "lshal -m" If I press fn+f6 I get the next output:

THE FIRST LINE IS GENERATED WITH FN+F5 THE REST IS GENERATED WITH ONLY ONE PRESS OF FN+F6

pexi@xxxxxx:~$ lshal -m

So ...
I did collect the needed data ... using a 10.04 live system without psb-graphic (only vesa).
the brightness key do change the brightness ... but without displaying this nice notifyer window.
Also all other (wlan, audio, displayswith) exapt numlock and hibranate ceased functionalaty.
This is totaly not satisfactory!!!

Okay all fixed, adding acpi_backlight=vendor to the kernel options fixed it, now it works just liked in 9.10.

@ Marcin...im a total n00b with linux....how do i do that?

I'm have brightness button problem too. It's not detect by xen programm. And of course no pop up in gnome then change brightness. Laptop Asus A6vm. In oldest version asus module this button work fine. About 3 years ago. But after change kernel module this key was lost.

Why is this bug marked "Incomplete". It looks like it's "Confirmed", if not even "Triaged" for Linux.

Note that nothing happende yet if i press Fn+F2/F3.....F9.

There's any solution available atm<'''??

If it's possible let me know

Regards

Ok, I found how the brightness can be adjusted by editing a text file:
1) Open a terminal and type sudo su to get root permissions
2) chmod 711 /sys/class/backlight/psb-bl/brightness to give permission to yourself to read/write the text file in question.
3)Use a text editor to open the text file, in the example it's leafpad: leafpad /sys/class/backlight/psb-bl/brightness
4) Choose a number from 1 - 100. You 'll probably want to set it somewhere inbetween (around 50 is ok). Save and you're done.

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.
