Hi there,
a friend of mine has problems with his NVIDIA graphics card: while the free 2D drivers are working without any problems (but with a bad performance) the proprietary drivers are not working properly: the screen is screwed up and only displays a white image with a coloured bar in the middle.
I checked the X.Org log file and found a message reporting problems regarding the resolution and the EDID:
At some places in the net (and here in the forum) it was mentioned that a fixed value for the EDID could help. But how can I set this fix value for the EDID in the xorg.conf?
Some more information about the system in question: it is a Dell Laptop with a 15,4" screen and a main resolution of 1280x800. The graphics card is identified in the X-log file as:
The distribution is an OpenSuse 10.3. The drivers are installed via the nvidia rpm packages for OpenSuse.
I would add the full X.org log, alas I am not allowed to add attachments (yet).
