When I start up kcontrol (either from the command line or from the KDE menu), it appears to start up okay, but the X process immediately pegs the CPU, and I can't do anything -- move windows, etc. The machine is still up; I can SSH in, but if I kill X, it scrambles the VT and I have to reboot to be able to use the machine from the console again. If I strace the 'X' process, I can see it's getting a stream of SIGALRMs from somewhere. Reproducible: Always Steps to Reproduce: 1. Start X with 'startkde' in .xinitrc 2. Run kcontrol Actual Results: X locks up, using 100% of the CPU Expected Results: worked.

Are you using any experimental xrender extensions?
Not that I'm aware of -- I'll attach my xorg.conf file.
Created attachment 57209 [details] xorg.conf here's /etc/X11/xorg.conf from the machine that's displaying the problem.
Quoting from the nvidia driver README: Option "RenderAccel" "boolean" Enable or disable hardware acceleration of the RENDER extension. THIS OPTION IS EXPERIMENTAL. ENABLE IT AT YOUR OWN RISK.
