Re: 7667 issues; black screen/ X windows crashing
I see a few problems.
At the top of your bug report, it shows that the 1.0-7667 nvidia kernel module is loaded. However, the nvidia driver install log further down in the bug report shows that you had installed 1.0-7676.
Your xorg.conf is still referencing the 'nv' driver rather than the 'nvidia' driver..
