I have an NVidia GeForce 6150SE nForce 430 (rev a2) graphics card and a HANNS G HW173D 1440x900 monitor. This was all working with openSUSE 11.1 a few hours ago. I installed Xen and rebooted. X Windows didn’t come up, so I went to the web site Use Nvidia driver with Xen - openSUSE and followed the instructions there. Everything was cool; I rebooted the machine and Xen came up 1440x900.
I don’t know exactly what I did next, but now I have only 1024x768, and SAX2 is not recognizing the monitor. And the LiveCD doesn’t see it either. Is it possible that the Nvidia driver fried something in the monitor or on the card? Changed a BIOS setting? Something happened. I am about to try a Fedora LiveCD to see if the monitor comes back to 1440x900. If that doesn’t work I’ll try Ubuntu. But I expected the openSUSE LiveCD to pick up the monitor, unless something got fried. Anything else I should try?
Well … neither Fedora nor Ubuntu sees the monitor any higher than 1024x768, so I’m guessing it’s a hardware problem. But I still don’t know if it’s the motherboard or the monitor. I checked the BIOS and there don’t seem to be any settings other than the amount of RAM set aside for framebuffers. Of course everything is out of warranty.
I would think the NVidia software would have some diagnostics I could run, and I haven’t seen anything show up in NVidia settings, so I am thinking it’s the monitor. That would be a good thing, since they’re cheaper than a motherboard.
