Comment 5 for bug 148686

Gert and Brenno, can you both please attach your Xorg.0.log and xorg.conf files, and the output from lspci -vvnn.

Sounds like perhaps you have some chipset-specific quirk. The logs should show what xserver was attempting to do.

If you wish, I've also packaged a version of -intel from upstream's git HEAD. I wouldn't recommend running this in general, as it has several other new issues (such as direct rendering failing), but you might find it interesting to test to see if the issue already has a fix identified. I don't think this is a serious enough issue for us to fix in Gutsy, since X eventually does come up.
