If the OEM used the integrated backlight controller in the GPU it should be exposed via sysfs (there should be a radeon entry in /sys/class/backlight). You can use that interface to control the backlight. Weird, the xubuntu 13.04 livecd can control brightness but the installed system not... investigating further Adam Groszer, Ubuntu 13.04 reached EOL on January 27, 2014. For more on this, please see https://wiki.ubuntu.com/Releases . If this is reproducible, it will help immensely if you filed a new report with Ubuntu by ensuring you have the package xdiagnose installed, and that you click the Yes button for attaching additional debugging information running the following from a terminal: ubuntu-bug xorg Also, please feel free to subscribe me to it.
