When I installed the distro I selected the non-free drivers, but I have some tearing, besides that the Catalyst Configuration Center does not open, if I try to open it from the terminal I get
amdcccle: error while loading shared libraries: libQtGui.so.4: can not open shared object file: No such file or directory`
So I wanted to switch to free drivers to see my performance. I uninstalled catalyst with
sudo mhwd -r pci video-catalyst and installed the free drivers with
sudo mhwd -a pci free 0300. When restarting I got an error that says
[FAILED]: Failed to start Light Display Manager
so I had to enter the terminal (Ctrl + Alt + F2) and return to catalyst.
Does anyone know what this error is due to and how can I install the free drivers? or how can I open catalyst to change the settings? Thanks.
