[Bug 1218547] Re: Clevo W350ST brightness keys don't work on Kubuntu
Surak, this bug was reported a while ago and there hasn't been any
activity in it recently. We were wondering if this is still an issue? If
so, could you please test for this with the latest development release
of Ubuntu? ISO images are available from http://cdimage.ubuntu.com
/daily-live/current/ .
If it remains an issue, could you please just make a comment to this.
Also, could you please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER
where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.13-rc1
This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing
If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER
As well, please remove the tag:
needs-upstream-testing
Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

** Description changed:
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
+ When trying the following event codes appear correctly:
