Bug Description
Binary package hint: kdemultimedia
Hi,
I'm using an up-to-date kubuntu ibex on a dell mini 9''.
The problem is that the backlight brightness is jumping around.
It looks like random. It jumps up and down without a simple pattern (AFAICS).
/sys/class/
The only workaround is to set the correct brightness using something like:
echo 10 > /sys/class/
Is works with the ubuntu preinstalled by dell.
That is why I'm filling this bug report against kdemultimedia...but I'm not sure...
It may be due to the fact that actual_brightness is only in a 0 15 range.
This is probably a duplicate of bug #278471.
Hmm, somebody said this before in more drastic terms but Kubuntu is a bit unstable at the moment.
