this has been going on for quite a while, and I've tried posting to the
forums without success, so I shall try here.
a while back I had a package that depended on the modular xorg, so I
went through and upgraded. I didn't change anything in my xorg.conf
file, but since the upgrade my system has been at at least 20% CPU usage
at any given time, and uptime always shows at least .50, and that's at a
complete idle.

When running any program, such as thunderbird, x-chat, firefox, etc.
when I move the window, scroll, or anything of the like it refreshes
from top to bottom, and takes up to 2 seconds to refresh the whole
window. if a new line shows up in x-chat, it redraws line after line of
text from top to bottom, hard as hell to read in #gentoo. I can't figure
it out.

now here comes the interesting part. I can watch a movie in mplayer just
fine, no issues at all. I tried playing a game, in this case glob2, and
it was slow as hell to refresh, and the mouse was jumpy. go figure

some info about the system:
- - I use xfce4 as my wm
- - it's a tyan mobo with an opteron 242 and a gig of ram
- - it used to work on 6.x
- - I have an nvidia graphics card

things I've tried
- - downgrading and upgrading the nvidia driver
- - switching between kernels from 2.6.14x to 2.6.16x
- - downgrading and upgrading xfce4 (that was hell trying to manage the
dependencies to do it properly)
- - skipping gdm and loading xfce4 via startxfce4 at cli

any ideas at all are more then welcome as nothing has worked so far

Thanks in advanced,
Kyle
