Comment 27 for bug 311748

Does it make a difference if you remove the secondary video card? Doing so could prove or disprove the hypothesis in comment #7.

Fwiw, I've a system with an ATI card and onboard Intel graphics, and also am seeing X fail to start up in Jaunty, and screen corruption when vt switching. However, this configuration worked properly in Intrepid, so it may be a separate bug. (Also, I don't see the same warning about multiple primary devices in the log file.)

Regarding the other bugs, please take care to limit one bug report per issue.
