Bug description:
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...
