When I log in to Ubuntu, I select Unity from the list of sessions (not Unity 2d). It logs in but is using Unity 2d instead of 3d. I read several bug reports for NVIDIA graphics cards but am unsure which apply to me. I tried solutions from each but did not find one that fixes the problem. Now, I am unsure if my bug is different, is being worked on, is fixed but I am not patching it correctly, or is planned to not be fixed. How do I determine this and find the right bug report to follow?
Also, I see that my video card is blacklisted (see below), but it is shown as being supported for Unity 3d. Is this because of a known bug and will it not be blacklisted in the future?
Here is my video card:
$ lspci | grep -i nvidia 01:00.0 VGA compatible controller: NVIDIA Corporation G72M [GeForce Go 7400] (rev a1)
The problem began when I upgraded from Ubuntu 10.04 to 12.04.
Here is some more debugging information.
