I finally got to try out the solution posted. Unfortunately, it did not work for me though. The error I now get is: 22.409] (II) LoadModule: "glx" [ 22.409] (II) Loading /usr/lib64/xorg/modules/extensions/libglx.so [ 22.409] (EE) Failed to load /usr/lib64/xorg/modules/extensions/libglx.so: libGL.so.1: cannot open shared object file: No such file or directory [ 22.409] (II) UnloadModule: "glx" [ 22.409] (II) Unloading glx [ 22.409] (EE) Failed to load module "glx" (loader failed, 7) I'll try a few more things to see if I can muddle through....
