Hello Linux Geeksters. There are issues with the Brightness setting on both Ubuntu 13.10 and Ubuntu 14.04, using Intel hardware. On this computers, the Settings option under the Brightness & Lock category does not do enything when used. Also on laptops, the brighness gets set to low and stays like that, even after the charging process has been completed, this forcing the users to remove the charger and insert it back, in order to restore the proper brightness.
A temporary solution for the Brightness issue has been found, however. Just create the /usr/share/X11/xorg.conf.d/20-intel.conf file:
$ sudo touch /usr/share/X11/xorg.conf.d/20-intel.conf
Next open it as root (or with sudo) gksudo gedit /usr/share/X11/xorg.conf.d/20-intel.conf and paste the below lines:
Option “Backlight” “intel_backlight”
Save the changes in the file, logout, log back in and the problem should be fixed.
