GPU HANG
Xorg failures occasionally hangs system. The Xwindowing system fails, but alternate console login on another terminal session still works. The system also occasionally shows artifacts similarly to the attached file Note the black stripe above "System Information" Other artifacts appear as triangles to the left of highly visible items; they appear almost entirely in the KDE Panel or Desktop.
An extract from the system logis appended. The GPU crash dump is attached
