You could check if your user account belongs to the video group, a common 
pitfall with AMD drivers.

"To add yourself to the video group you will need sudo privileges; you can 
issue the following command:

sudo usermod -a -G video $LOGNAME 

You will need to log out and in again to activate this change.“
