** Description changed:
Hello, i have a msi ex600 laptop and just installed xubuntu 12.04 precise
pangolin. But i have a problem with my backlight. At first i could not set
properly my backlight via function keys, when i tried to set it, it was going
to the maximum brightness always , but later i googled the problem and added to
/etc/X11/xorg.conf file
Section "Device"
Identifier "Default Device"
Option "RegistryDwords" "EnableBrightnessControl=1"
Option "NoLogo" "True"
EndSection
this section.
Now i can properly set my backlight on login screen, it works as normal but
when i login to my account, i cannot change my backlight still as usual. if i
try to increase one step it goes to maximum, if i try to decrease it goes to
minimum, there is no option to change it step by step...
i had a similar problem with xubuntu and ubuntu 11.10 , i solved it but
i don't remember how i managed it.
Thanks in advance...
