Bug Description
hi,
i currently have a brightness issue on my notebook. In fact i have this problem a little longer, but i was hoping that it will be corrected with the time... unfortunately it is not the case (may i be the only person trying karmic on this notebook ?!?)
so here is the problem :
when i boot on karmic, i can't increase or decrease the brightness, and by default it's really dark.
the only solution i found, is really a stupid one :(
switch from X to VT1
use the FN + brightness down key => i receive an error message "ACPI: Failed to switch the brightness", but it don't work
funnily the brightness up key don't work too, but don't give me any error message
i close the notebook
i open it and switch to X
if i'm lucky it work
if not i need to do all that stuff again (i don't need to do this a lot, maximum 3 or 4 times)
if first through it may be an KMS problem (because KMS disable brightness on my other notebook) so i already disabled it.
but even after disabling it, netheir my brightness keys, xbacklight, or the brightness applet worked :(
