max res @ 640x480 res with KVM


I just went nuts trying to figure out what made my screen resolution drop to 640x480 and unable to raise back up. When I unplugged my KVM and went directly from monitor-->computer, it jumped back up to 1280x1024.

I'm going to assume that the KVM is causing some auto-detect problems. Is there any way I can FORCE X to use 1280x1024

On the other hand, it might be that the KVM is actually a hardware bottleneck. Is this the case? Do I have to buy a new KVM or is this just a configuration issue?

---------------------------------

Although I doubt it's relevant, here's some specs:

I'm running Gentoo Linux.
Code:
guttersnipe ~ # uname -a
Linux guttersnipe 2.6.23-gentoo-r3 #1 SMP Tue Jan 29 09:57:55 EST 2008 x86_64 AMD Athlon(tm) 64 X2 Dual Core Processor 4800+ AuthenticAMD GNU/Linux
Code:
guttersnipe ~ # lspci | grep -i nvidia
02:00.0 VGA compatible controller: nVidia Corporation NV44 [GeForce 6200 LE] (rev a1)

TIA!

Where were you seeing that the resolution was 640x480, on the monitor side or on the actual X side? If X says it is running at 1280x1024 and the monitor is showing a 640x480 image, then I would say it is an issue with the KVM.

You need to figure out what resolution the machine thinks is getting to the monitor to determine where the problem is. This is an odd issue though, since I wouldn't expect a KVM to have such an effect.

How do I do that?

I'm running with the nvidia proprietary drivers.
Code:
# nvidia-settings
showed 640x480 as the current resolution when the KVM was hooked up. It only let me select from 320x240 and 640x480. When I remove the KVM, it goes up to 1600x1024.
