Unable to modify brightness with driver 295.59 and xorg 1.11.4
I have laptop Dell Inspiron 13z. It uses Nvidia G105M. I used to have Ubuntu 11.04 using the option on xorg.conf:
Option “RegistryDwords” “EnableBrightnessControl=1″
Since I upgraded to Ubuntu 12.04 I can't handle my brightness due to an incompatibility between that option and the new xorg version.
Any suggestion? I would like to either manage the brightness or have it full for ever.
Thank you in advance.
