I was experiencing this problem with a Dell Dimension 2300 desktop (Intel 82845G/GL[Brookdale-G]/GE Graphics Chipset).

Speculating that this was a configuration issue in Karmic, I switched back to using an xorg.conf file I had used with Jaunty after following this guide: http://ubuntuforums.org/showthread.php?t=1130582 to improve graphics performance in Jaunty.

I have not experienced a freeze since I started using this xorg.conf file again. I think the reason may be that it disables tiling. From the guide:

"N.B.: If you are using an Intel 8xx chipset, tiling cause instability unless you use the Bleeding-Edge configuration. Therefore: if you are using the Safe/Optimal configurations, set tiling to false; if you are using the Bleeding-Edge configuration, set tiling to true."

The "Bleeding-Edge" configuration it refers to involved using drivers from the xorg-edgers PPA. I was using the "Optimal" configuration and therefore set tiling to false in my xorg.conf. What I suspect is that Karmic's default intel driver has this tiling issue, and it is enabled by default for those who do not use an xorg.conf.
