Re: More Than one Matching Device section for instances found: nvidia
The bug report you attached doesn't seem to include X crashing. I see it running at 2560 x 1024. Was it generated immediately after X had crashed?
I have a few questions:
0) Why are you using the NoPowerConnectorCheck and NoBandWidthTest X options? Does this problem go away if you remove them?
1) Why are you using the ConnectedMonitor option?
2) What kind of motherboard and BIOS version are you using?
