Xorg 100% CPU with nvidia driver
I've just switched over to the nvidia driver from nouvou. Everything is working, however Xorg CPU utilization is 100% of a single core (fortunately I'm running on an I7 so I can still function).
Some notes that might help...
X utilization starts normal but hits 100% after about one or two minutes (varies).
This happens even when not logged in via X (i.e., Login screen is up - I see the 100% via ssh... and the sound of the cpu fan spooling up).
If I kill X, things go back to normal for a while.
I can kill X and keep it dead and log in remotely (XDMCP) and don't see the utilization.
I've gone through this board and fixed everything I can see (selinux, etc.). I don't have any of the errors I'm told to look for.
I've attached the requisite bug report file that seems to have all requested data.
Meanwhile, I'll probably go to runlevel 3 for a while.
Re: Xorg 100% CPU with nvidia driver
I think I've solved this... after much searching on the web, I found a reference to Device options "UseEvents" "on";
That seems to have done the trick.
Update: spoke too soon... just took a bit longer this time to hit 100% :(
update 2: actually seems to be fixed with UseEvents. Spiked for a bit then settled down. Now seems OK whether logged in or not.
Re: Xorg 100% CPU with nvidia driver (solved?)
Ok - I fell back to the nouveau driver and still had issues. Today I came across this: https://bugzilla.redhat.com/show_bug.cgi?id=475890
Long story short: X was moved from vt7 to vt1. Init is running a tty on tty1. That is what's been causing CPU utilization issues for xorg of late (at least for me).
I've attached a small patch to the above mentioned bug report that solves my issue ... although I haven't tried yet with the proprietary driver (as I moved to 2.6.32rc8 for other reasons).
