Brightness hotkeys only work after suspending/resuming system.

[Rick Ucker]

All hotkeys except brightness work normally. Brightness hotkeys (fn+f6/f7) only begin to work after I suspend & resume once. After that, they work perfectly until the next reboot. Before I suspend & resume, xev and acpi_listen report no keypress when I press the hotkeys, which are fn+f6/f7.

The affected system is a Toshiba Satellite a305-s6857 running 10.10.

I created a new user account, logged in after booting up, and the issue was unchanged. So, this doesn't appear to be a config issue with my dot files.

Once it starts working (after I suspend & resume), the outputs are this:

acpi_listen: fn+f6, then fn+f7:
video DD03 00000087 00000000
video DD03 00000086 00000000

xev: fn+f6:

I am reporting this against the linux package as per https://wiki.ubuntu.com/Hotkeys/Troubleshooting (I got all the way to step 6-2 with no success).

Kind of sounds like a bios bug to me :(.

[Jeremy Foshee (jeremyfoshee)]

Hi Rick,

If you could also please 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.

Hi Jeremy, I tried two things:

   1. At the recommendation of Chase (also subscribed to this bug) I
   installed the backported 2.6.37-12-generic-26~lucid1-ubuntu kernel from
   here.<http://ppa.launchpad.net/kernel-ppa/ppa/ubuntu/pool/main/l/linux-lts-backport-natty/>No
change in behavior.
   2. At your recommendation, I installed 2.6.37-999-generic #201101190911.
   With this kernel, I actually suffered a regression: I can't change
   brightness at all (even after suspend/resume), either via the hotkeys or via
   the Gnome Power Manager Brightness Applet. The latter used to work no matter
   what (no suspend/resume needed), but now I see a red slash with a circle
   around it at the center of the Brightness Applet icon. It also has a tooltip
   that reads: "Cannot get laptop panel brightness."
