You are talking about "If you have a problem, PLEASE read this first"?
I hope so
... Here is the nvidia-bug-report.
I had to gzip it because it is pretty big.
I added also the log of Xorg.1.log at the of the regular nvidia-bug-report.log, because that is the log file of the 2nd Xorg server (started with -logverbose 6). I can split it in two files if you want.
I hope you have an idea, what is going on.
Thanks a lot.
