[Bug 1218547] Re: Clevo W350ST brightness keys don't work on Kubuntu
I booted with acpi_backlight=vendor and the Fn+F8 and Fn+F9 keys worked
as expected to control the internal laptop screen brightness. But there
was a side effect: now, plugin the external VGA does not change to
external screen automatically anymore. And after manually changing to
the external VGA in KDE and removing the VGA cable does not change back
to the internal laptop screen automatically. I hope there is a way to
keep Fn brightness keys working and the automatic screen selection,
simultaneously.

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

in my package sources
Thanks!
