Public bug reported:
I've recently installed Kubuntu Karmic 9.10 from new. I'm not completely new to
Linux, tough.
Couldn't say when this bug started exactly, but it probably came with this
latest release.
I own a MSI-Wind netbook and i've previously been using Ubuntu 8.10 and Kubuntu
8.10 & 9.04 and never experienced this trouble.
The problem is the following:
whether i use the fn keys or the slider in the power management settings panel
in order to adjust the brightness, it starts going up and down by itself (note
that in either case i just press/change it by one step) and never stops.
-> As in previous releases (as well as this does) the gui brightness
indicator shows up and indicates correctly the actual brightness
strength. It just goes up and down forever. Just to give you an idea, it
changes brightness intensity about 10 times per second and never calms
down. (The symptom is just as if i got fun pressing madly the up and
down fn keys, while i'm effectively pressing them just one time).
The only way i've discovered to stop this madness is to reboot the whole
machine.
NOTE: i've discovered that fn keys work right in the pre-grub and grub
loading times, and that in that 'short' time i can adjust brightness
without having the problem. Once i log in the system i get no chance to
press brghtness fn keys once and not experiencing the automatically
up&down problem.
What can i do to remedy to this? It must be something simple, i reckon
(because in previously releases it worked right).
Tell me what you need and i'll give you :P
Thanks for your future help :D
(PS: i'm italian, but i used english to get to a wider slice of people.
So if you're italian too, don't get mad with english and just speak your
language if you want.)
