Try this:

find the PIDs of your X-server, your window manager, and your file
manager.

After X-Windows starts, for each PID, run as root:

renice -20 WHATEVERTHATPIDWAS

And see how that helps.  There's a way to do this automatically on
startup, but it depends on how you are doing logins (xdm, gdm, startx,
etc).
