Description Ilya Korniyko 2005-05-19 16:18:02 UTC 
Version:            (using KDE KDE 3.4.0)
Installed from:    Compiled From Sources
OS:                Linux

it is because of changed format of /proc/dri/0/name in newer Linux'es (X.org or new kernel matter?)

So the following line 
  QRegExp rx = QRegExp("\\bPCI:([0-9a-fA-F]:[0-9a-fA-F]:[0-9a-fA-F])\\b");

in file "kcontrol/info/opengl.cpp" in function "static bool get_dri_device()"

should be updated to allow wider format
