Please change/merge bugreport
it would be very nice, if you could correct the following bugreports;
1. #581840 = please close this bug, as it merges with bug #583613
2. #583613 = this report at the moment is targeted to package "nvidia-glx"
which is NOT the correct target. This bug has nothing to do with nvidia-glx
(proved it). The correct target for this bugreport might be either xserver-
xorg, udev or the kernel itself. It is not amd-64 related.
Thank you very much for your attention and for all the help!
