The usual failure causing this is a hotplug interrupt getting stuck so the desktop keeps getting told that things have changed, then it asks what's changed, and getting the answer is expensive. Also, could you try linus master kernel? There have been some fixes in the hotplug area there. I can't reproduce this bug anymore with kernel 2.6.31.5-91.rc1.fc12.x86_64. I still have this problem with the latest Fedora 12 kernel - 2.6.31.12-174.2.3.fc12.i686.PAE. This is also with an X4500 graphics card. I've reduced the incidence of the problem using "nomodeset" in the kernel boot options and Option "AccelMethod" "EXA" in the Device section of xorg.conf. But every so often when under stress X still slows to a crawl. Killing udevd is a fix, but an ugly one. yohan has reported this is fixed for him, pls open new bug for your problem which may be different. |

It's sluggish even in GDM at startup but it's worse when using firefox : it's getting slower and slower until X seems to be freezed and hard reboot is needed. The uncompressed Xorg log weights 15M. sysprof points to drm_do_probe_ddc_edid. I don't have a Xorg.conf and i don't use composition.
