xorg gets slow after extended usage with new monitor)

Hey guys,

I just bought a 22" widescreen monitor to connect to my tiny little laptop (thinkpad x60). I set it up to use xrandr with the intel driver as discussed here:

http://www.thinkwiki.org/wiki/Intel_Gra … .22_driver

and it works great. Except that after I've been running it for a while (even sitting idle while I make dinner), X starts to eat CPU and things like switching desktops or scrolling the window become unresponsive. It seems like every time I request a client redraw it demands too much. I have to restart X and then everything is lovely for a while.

I'm thinking maybe when I deleted old dualhead stuff from my xorg.conf maybe I deleted something that was giving me extra hardware acceleration or clearing memory or some such. So I'm hoping if I post my xorg.conf here somebody can say "hey you should enable option something" and It'll be all fixed. Otherwise I need some other sort of advice. Maybe its my window manager (pekwm) or something else? Any ideas?

Dusty

PS: Any unrelated tips for improving xorg.conf are always welcome. ;-)

that'd be the hard drive, I'm more concerned about X. ;-)

I had supposed that slow drives would affect your displays and sata drives do show slowdowns in dmesg.
