[SOLVED] Cannot Change Screen Resolution
Today, I reinstalled Arch — I replaced the Windows partition with a new / partition, and the old partition became /home. Now, with the new installation, in X, I cannot get a resolution higher than 1024*768. xrandr lists 1280*960 among others, but if I try to switch to it, the video card stops sending the video signal to the monitor and the only way out is to raise elephants.
Hardware:
Video Card: NVIDIA RIVA TNT2
Monitor: ViewSonic A70f+
I am using the nouveau driver for now. In the old installation, I believe I was using nv.
How do I fix this?

Re: [SOLVED] Cannot Change Screen Resolution
Any errors in the logs? Do you switch the refresh rate too or just the resolution?

Re: [SOLVED] Cannot Change Screen Resolution
I had this problem on an old laptop with an Nvidia Geforce4 460 Go when I upgraded to the newest X server and nv driver not so long ago. I fixed it by adding `nomodeset` to the kernel boot line. It seems the newest nv driver wasn't playing nice with the kernel for selecting higher resolution video modes, but with that added X auto detected all resolutions correctly. So you could try that.

Re: [SOLVED] Cannot Change Screen Resolution
Adding nomodeset fixed it. The resolution is now a surprising 1400*1050:

I didn't know my monitor was capable of 1400*1050. I thought its maximum was 1280*1024.
It also got rid of the framebuffer... heh heh
I also switched back to the nv driver.
[2010-12-19T12:19-0600] Update: That's odd... It went back down to 1280*960. Oh well, I originally wanted that resolution anyway: http://img.ly/system/uploads/000/632/75 … _scrot.png
