Too high CPU load while starting Xfce4

Padawan.AVT · 11-01-2009, 02:43 PM

Hi! When I start X session (Xfce4), it completely loads one of my CPU cores for a few minutes (sometimes even for 30-40 minutes).
In the meantime my /var/log/Xorg.0.log log almost completely consists of such continuously repeating records:

After a hundred or so lines of common startx diagnostics information comes a few thousand lines of this garbage.

What is the reason of such behavior?

I think the problem is not with XFCE, problem with X.Org and with his libraries.
Check xorg.conf.
