Default NVS 140M - nVidia 260.19.06 - Xorg 1.9 eating 100% of one cpu core

I have a Quadro NVS 140M and I started with Kubuntu 8.04 then I upgraded to 10.04 and finally 10.10+KDE 4.5.2+nvidia driver version 260.19.06+QT 4.7

Since when I upgraded to Kubuntu 10.04 performances were really embarassing, right now with Kubuntu 10.10 is even worse.
What happens seems after some usage one cpu core start to be fully busy with Xorg.

I tried to disable all visual effects from KDE panel, but doesn't help.
I tried to disable all Fonts AA options, but doesn't help.

I'm desperate, because the system is barely usable.

My suspects are:
1. nvidia bug
2. x bug
3. some old configuration is still there and never got killed during upgrades

Please help me

I have exactly the same problem and I believe it's the new version of Xorg server. I have done fedora upgrade from 13 to 14, I also tried a fresh install of fedora 14 - no luck :-(.

I have also tried older drivers from nvidia site as well as packaged drivers from fedora - still the same issue.

Updated to 260.19.29 and I still have the issue. Any hope to get this debugged at least?

Funny thing: I found that when the issue happens if I lock the notebook using Euphoria (GL) screensaver and then unlock back the issue is vanished for a while.

So seems definitely some thread is stuck doing something.
Would be nice to know where exactly get stuck.

BTW: Upgrade to nvidia beta driver 270.18 and X 1.9.2.901 (10902901) but this didn't solve the issue.

I am running Fedora 14 with NVS140M on Thinkpad and don't have any of these
problems. Did you do alll the updates for Fedora 14?
