X11 using up resources?

[Shaun Bolling]

I experience this with RH ES v4 on a Dell 2850. I fixed it by turning 
hyper threading off and switching the video driver in the xorg.conf.

pico /etc/X11/xorg.conf

I commented the driver line and added the vesa driver.

Section "Device"
         Identifier  "Videocard0"
#       Driver      "radeon"
         Driver      "vesa"
         VendorName  "Videocard vendor"
         BoardName   "ATI Radeon 7000"
EndSection

Hope this helps.
