Red Hat Bugzilla – Bug 772923
problems with brightness and volume with fedora 16 and thinkpad t60
Last modified: 2012-09-10 08:57:13 EDT
Description of problem:
the brightness control via function keys is no more working in fedora 16. pressing the function keys for increasing and decreasing the lcd brightness shows the osd on gnome but nothing happens.
the same happens with the function dim screen to save power in the system settings, nothing happens.
works as expected
for the volume control i had to add options thinkpad_acpi hotkey=0x00ffffff to the thinkpad_acpi module parameters
Version-Release number of selected component (if applicable):
description: ThinkPad ACPI Extras
install f16 on t60. use function keys
the lcd brightness does not work
the volume cotrol works with a workaround
I want to say that I have almost the same issue on my Toshiba Tecra M9.
The hotkeys for brightness are completely dead in my case.
However, they worked with the live image of F16.
After installing and updating the system to current status (current kernel is 3.1.9-1.fc16.i686) the keys stopped working completely.
The other hotkeys work as normal though.
Also the brightness control in the Screen applet of System Settings is gone.
Funny enough it is seen very very briefly when the applet is started, but disappears immediately.
Is this still being seen with the 3.4 or 3.5 kernels in F16/F17? If so, could you please attach the output of dmesg and lsmod after a fresh boot?
This is currently working for me on my Tecra M9.
PS: as I am looking at Fedora to work 100% on Toshiba's, how and were do I report non-working hot-keys? Here in Bugzilla?
I mean, I believe this is not a Fedora-thing since hotkey-mappings are done somewhere else - upstream in some package? Kernel?

Great. Thanks for letting us know.

You can file them in bugzilla, but often it is more expedient to report issues to the firstname.lastname@example.org list directly.
