Adjusting brightness with hot keys doesn't work properly on Asus K55VD-SX205R

[Dmitriy Kodanev]

Full computer model: ASUS K55VD-SX205R

What you expected to happen:
When you push Fn+F5 brightness of screen of Asus K55VD notebook decreases.
When you push Fn+F6 brightness of screen of Asus K55VD notebook increases.

What happened instead:
Hot keys that adjust brightness (Fn+F5, Fn+F6) don't work. Brightness stays the same.

WORKAROUND: 1. sudo gedit /etc/default/grub
2. find the line starting with GRUB_CMDLINE_LINUX_DEFAULT
3. add "acpi_osi=" to the options
4. sudo update-grub2
5. reboot

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.8 kernel[0] (Not a kernel in the daily directory) and install both the linux-image and linux-image-extra .deb packages.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

[Dmitriy Kodanev (dkodanev)]

I've tested kernel from v3.8-rc4-raring directory in http:/http://kernel.ubuntu.com/~kernel-ppa/mainline/.
With workaround ("acpi_osi=") hot keys work just as when I use kernel 3.5 from Xubuntu 12.10. But when I delete these symbols, then do "update-grub2" in terminal and reboot, the situation remains the same as I have not used new kernel,so that Fn+F5/F6 combinations can't adjust brightness.

[penalvch (penalvch)]

Dmitriy Kodanev, thank you for testing the newest mainline kernel. Did this problem not occur in a release prior to Quantal?

[Dmitriy Kodanev (dkodanev)]

As you can see,
> InstallationDate: Installed on 2013-01-18 (4 days ago)
So I haven't installed 12.04 before installing 12.10 on this laptop. This wasn't upgrade, it was clean install of Quantal on my laptop.
What I have tested few minutes ago is trying with Xubuntu 12.04 in live mode (of course, I don't want to reinstall my system, I only tried live mode). I may say that my experience showed that not only Fn+F5 and Fn+F6 do not work there, but even all other hot Fn keys do nothing, except of Fn+F2 (wireless off/on) and Fn+F7 (laptop screen off/on). Adjusting of sound level (Fn+F10/F11/F12) doesn't work in Xubuntu 12.04 as well as adjusting brightness. So, I may confirm that this problem occur in Precise.

[penalvch (penalvch)]

Dmitry Kodanev, thank you for testing Precise. For regression testing purposes, could you please test a Lucid live environment via http://releases.ubuntu.com/lucid/ ?

[Dmitriy Kodanev (dkodanev)]

I have tested Lucid 10.04 Live (I used Unetbootin and USB flash disk). No
luck. As I predicted to myself these hot keys don't work. It was
2.6.32-38-generic kernel.

Dmitriy Kodanev, thank you for testing Lucid. Could you please test http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.8-rc5-raring/ ?

[Dmitriy Kodanev (dkodanev)]

I've tried this kernel and I may say the problem persists. I don't remember how it was in v3.8-rc4-raring but with the most new kernel I cannot adjust brightness with any tool. In Quantal I could adjust it with xfce4-brightness-plugin 1.2.0 applet, but with tested kernel I couldn't do it, brightness was always on the same level, though I moved the indicator of level.

[Chris (angryfirelord)]

I ran into a similar problem with my Asus K55A laptop. Initially, I was playing around with 12.04 and Fedora 17 and the brightness hotkeys were working. Later on, I went to test Windows 8 on it, I wiped out the partitions on it. However, I did have to do a BIOS update on it. Later on, I got sick of windows 8, put 7 and Ubuntu back on and now the brightness hotkeys don't work.

I suspect it's a BIOS incompatibility, but I don't know for sure. Fedora 18 also has the same problem. I'll test some older Ubuntu builds just to make sure it's not a regression.

[Dmitriy Kodanev (dkodanev)]

This workaround works for me in Xubuntu 13.04:

https://help.ubuntu.com/community/AsusZenbookPrime#Ubuntu_13.04

Using:

GRUB_CMDLINE_LINUX_DEFAULT="splash quiet acpi_osi='!Windows 2012'"

All function keys work now.

[penalvch (penalvch)]

Dmitriy Kodanev, thank you for providing the WORKAROUND. As per www.service.asus.com/ an update is available for your BIOS (411). If you update to this, and undo any WORKAROUNDs, does this change anything?

[Dmitriy Kodanev (dkodanev)]

I've updated BIOS of my laptop to version 411. Without any workaround
nothing works with adjusting brightness keys. With "acpi_osi='!Windows
2012'" work ALL Fn+Fx keys!
I only can tell that if I manually adjust brightness with
xfce4-brightness-plugin notifier, e.g. if I make it low, then if I hit
either Fn+F5 or Fn+F6, brightness changes upto about 80-85 per cent (as I
can see in xfce brightness notifier).

Dmitriy Kodanev, thank you for testing the latest BIOS. Could you please undo any WORKAROUNDS, and test the newest mainline kernel via http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.9.1-saucy/ ?
