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. perfoming: echo "1">/sys/class/backlight/acpi_video0/brightness 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): kernel 3.1.7-1.fc16.i686.PAE /lib/modules/3.1.7-1.fc16.i686.PAE/kernel/drivers/platform/x86/thinkpad_acpi.ko license: GPL version: 0.24 description: ThinkPad ACPI Extras How reproducible: install f16 on t60. use function keys Actual results: the lcd brightness does not work the volume cotrol works with a workaround Expected results: everything works Additional info:
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. BR Tom
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?
Hi Josh This is currently working for me on my Tecra M9. Thanks! 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? Please advice. BR Tom

You can file them in bugzilla, but often it is more expedient to report issues to the platform-driver-x86.org list directly.
