Bug Description

Was originally running 14.04-desktop in a VmWare Fusion v5-Pro guest. Ran fine for quite a while. A certain update a few months ago introduced an issue where I could no longer log in graphically. The guest console would present a normal login after boot, but attempting to log in causes the screen to display a tiled background and a failure to present any UI components. Ssh access remains accessible, so it seems to be purely a graphical desktop problem.

Anyway, I have since tried many things, including ensuring I had the latest updates, reinstalling unity, upgrading to 14.10, and upgrading Fusion to v7-Pro. The result is exactly the same. I will attach a screenshot.

To be fair, I do not know for sure this is a unity bug. But it is my best guess.

Looking at the attached information I see this.

That indicates a messed-up video driver installation.

Also this.

Also indicates a pretty messed-up video driver installation. This is unlikely to be a bug in Unity, since Unity isn't even run because the installed video driver does not support the basic functionality required. The attached screenshot shows Unity is not running.

Thank for you taking the time to look into the issue.

Do note that I freely admit that I am not sure whether the problem is in Unity. However, also note that the problem does strongly suggest it is related to ubuntu at some level as everything _was_ working until a specific apt-get upgrade was executed (I wish I had more details about the one that broke things).

So, if the problem is not in Unity, any ideas on who needs to be looking at the issue?

The behavior has changed slightly. Now instead of getting a tiled (and hung) background, the system just boots me back to the login prompt after trying to do something for about 1 second.

This screen capture shows the latest behavior. Note that it does the same thing whether I log in "Greg" or the "Guest" account, ruling out something specific to the users /home
