Like my two compadres above, I'm encountering the same symptoms. Upgraded from Karmic, doesn't work, but does work for a brand new user. I've looked into my xsessions-error but fixed all the errors, to no avail. I'm currently working around the problem by launching "/usr/bin/compiz" at startup, which apparently forces the loading of the video drivers.
It is the loading of the video drivers that's problematic, I think. When changing the visual effects settings from "None" to anything else in Simple CompizConfig Settings Manager, it forces the reloading of the drivers, and then, things work.
Still, I know I may be a bit harsh, but this definitely-not-minor bug has been around since day 1, and is still not fixed... It's a bit frightening for a LTS version. With that problem and all-around (relative) instability, I find it difficult to defend Ubuntu when talking about OS merits with Windows- or Mac-users.
