I have been going crazy trying to figure why I can't get these drivers to work. When I go to hardware drivers under system-administration, it tells me I have fglrx installed, but whenever I try to change my graphics settings on my desktop, it tells me I cannot. In terminal, the command fglrxinfo gives me a segmentation fault, and I cannot even guess what that might mean. I installed(attempted to) the driver using the commands
lsmod displays the list of kernel modules currently loaded and dmesg displays kernel messages so one of then should show fglrx somewhere in the output. if not, fglrx is most likely not being used at all.
actually, an easier way to check is:
which should display OpenGL info. look at OpenGL renderer string and it should ATI/AMD.
