Xorg 1.9.0 maxing CPU on 10.10 with nvidia drivers 260.19.44 with GTX 460 card

Asked by zubin ghai

I just plugged in a replacement for my 8600 GT card, rebooted, and found Xorg to be maxing out the CPU. There are no visible errors in the Xorg.0.log file. I re-enabled TwinView (old settings), reinstalled the nvidia driver from the .run file from the nvidia site, restarted X, disabled compiz and Composite in xorg.conf... to no avail. Card otherwise is working perfectly fine, but Xorg doesn't seem to like it.

I plugged back in the 8600 GT, and Xorg is behaving itself again. 2.3% usage.

What's going on? Where do I start looking? I thought of dropping a version or switching to the built-in ubuntu nvidia drivers, but I'd like to hear if anyone knows what's going on or have step-by-step instructions on what I should be trying or where I should be looking before I spend too much time trying to debug video problems on ubuntu again! :-S

Keep the original card in and uninstall the nvidia driver then rename xorg.conf (if you have one), reboot to the OS again and make sure the driver used is the open driver. Check with:

sudo lshw -C display

if the driver line says "nouveau" or "nv" then you are good to go, switch the card as usual and reboot, then install the proprietary driver again.

FWIW, and although it's probably irrelevant, I also updated to 270.41.06. Following your instructions to the letter resolved the issue no problem :) Xorg and me are happy!

Thanks again!
