However if I use:
lspci -nn | grep VGA
I get the following result:
01:00.0 VGA compatible controller : Advanced Micro Devices, Inc. [AMD/ATI] Cayman PRO [Radeon HD 6950] [1002:6719]
Which states that he does recognize it. What am I missing? I have tried to reinstall the mesa-glx und stuff in that direction, but I'm really a beginner. Is the graphic card broken?
