And /sys/class/backlight is empty.

I tried to modprobe all backlight modules:

dpkg-query -L linux-image-extra-3.11.0-12-generic|grep backlight\/|sed 's/.*\///; s/\.ko//' > /tmp/1
for i in `cat /tmp/1`; do sudo modprobe $i; done

but /sys/class/backlight is still empty.

I also tried the xbacklight utility, it has no effect.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.12 kernel[0].

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.

I installed and booted http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.12-rc5-saucy/linux-image-3.12.0-031200rc5-generic_3.12.0-031200rc5.201310131952_amd64.deb, and now Fn+F3 (wifi switch) and Fn+F7 (touchpad switch) work, but Fn+left/right (brightness) still doesn't work.
