You probably want UXA, seems to fix a lot of issues on Intel at least
for me, and I had better luck with the video drivers in Jaunty
specifically.

You can add it to your Device stanza in /etc/x11/xorg.conf:

Section "Device"
        Identifier      "Configured Video Device"
        Option          "AccelMethod" "UXA"
        Option          "UseFBDev"    "true"
EndSection

The only side effect I've discovered are random freezeups of the X
server that don't seem to have any rhyme or reason to them. But I
looked at the release notes for Jaunty and it seems that either one
needs to wait until Karmic comes out, or that the fixes described for
this issue are mutually exclusive somehow. At least that's what I
grokked from the notes.

I have UXA enabled on both my desktop on my laptop. My desktop has an
ASUS P5QL-EM - Q33 graphics chipset, and the laptop has an Intel
Mobile Graphics Accelerator 4 for video. I almost never get freezeups
on the laptop, only the desktop, every 2 or 3 days.
