Re: nvidia drivers won't work on Knubuntu 7.04 AMD64
According to the new bug report, you have a completely different problem. The driver is detecting two display devices, CRT & DFP. No EDID is being detected for the CRT.
How many display devices are you trying to use? If you only wish to use the DFP, then try adding the following to the Device section of xorg.conf:
Option "UseDisplayDevice" "DFP"
