Comment 18 for bug 728745

We are currently blacklisting those card to avoid non technical user to get a bad unity experience when upgrading to the nvidia binary driver.
For technical user wanting to use it with nouveau (we don't support nouveau with compiz or unity, be warned that you can get some memory leaks and other glitches depending on your card), you can set UNITY_FORCE_START=1 in /etc/environment to bypass the detection.

Please just report "lspci -nn" and not "lspci -v" as it hides the id we need and we need to dig in the map file to find it back ;). Otacon, I've done that for your case, no need to repost, thanks :)
