[Bug 1218547] Re: Clevo W350ST brightness keys don't work on Kubuntu
I have a Clevo W350ST with Ubuntu Saucy, had installed the Bumblebee PPA
and experienced the same problem with the brightness keys not working.
However, by removing the bumblebee PPA, purging bumblebee, re-installing
it from the Saucy repos, and then adding kernel boot parameters
"acpi_backlight=vendor" and "acpi=force", and now the Fn-F8/F8 correctly
alter the brightness correctly.

Title:
Clevo W350ST brightness keys don't work on Kubuntu
Status in “linux” package in Ubuntu:
Confirmed
Bug description:
The Fn+F8 and Fn+F9 keys are not working on my Clevo W350ST with
Kubuntu Raring to change screen brightness of the internal laptop
screen. I installed linux-headers-3.11.0-4, linux-
headers-3.11.0-4-generic, linux-image-3.11.0-4-generic and linux-
image-extra-3.11.0-4-generic from Saucy packages repository but the
problem persists.
When trying:
$ xev | sed -n 's/^.*state \([0-9].*\), keycode *\([0-9]\+\) *\(.*\), .*$/keycode \2 = \3, state = \1/p'
keycode 36 = (keysym 0xff0d, Return), state = 0x10
keycode 232 = (keysym 0x1008ff03, XF86MonBrightnessDown), state = 0x10
keycode 233 = (keysym 0x1008ff02, XF86MonBrightnessUp), state = 0x10
Event codes appear correctly.
And changing:
/sys/class/backlight/intel_backlight/brightness
changes the brightness of the screen, but pressing the key combination
does not. I believe this happens because the key combination is, in
fact, changing the value of
/sys/class/backlight/acpi_video0/brightness
I have

http://ppa.launchpad.net/bumblebee/stable/ubuntu
in my package sources
Thanks!
