Guest session from a running session fails to start unity or bail out to another desktop

[Someone]

Guest session from a running session is different and weird compared to guest session from the login screen.

Steps to reproduce:
1. In a running session press your name in the top bar and select guest session.

I expected to receive the same session type as when pressing Guest Session in LightDM.
I received a strange session type which I don't recognize and can't exit.

The session I use for my normal user is Ubuntu (aka Unity 3D)

Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately, we cannot work on this bug because your description didn't include enough information. You may find it helpful to read "How to report bugs effectively" http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you would then provide a more complete description of the problem.

We have instructions on debugging some types of problems at http://wiki.ubuntu.com/DebuggingProcedures

At a minimum, we need:
1. the specific steps or actions you took that caused you to encounter the problem,
2. the behavior you expected, and
3. the behavior you actually encountered (in as much detail as possible).
Thanks!

What session do you use for your user?

[Sebastien Bacher (seb128)]

Could you copy the .xsession-errors from that session and add it to the bug? you should be able to use the fileselector from the bar display on the top of the screen

[Sebastien Bacher (seb128)]

What videocard do you use? It seems like the 3d doesn't work for the second xsession on your configuration and that the bailer doesn't manage to fall back to unity-2d

[Sebastien Bacher (seb128)]

Could you also run "/usr/lib/nux/unity_support_test -p -f" in the question session? you can probably use nautilus to browse to /usr/bin and run things from there

Strange that it says Unity 3D unsupported as my previous session was unity 3D.

I'm running Ubuntu under VirtualBox so it might be related to the 3D acceleration support from VirtualBox acting up (The module vboxvideo form the guest additions)

Thankfully the ctrl+alt+t shortcut to open a terminal still works in this strange session so I can use a terminal to run commands and programs freely.

Status changed to 'Confirmed' because the bug affects multiple users.

[Omer Akram (om26er)]

I am tempted to mark this bug as invalid considering it a VirtualBox driver bug.

The same problem without a virtualbox. There are a full description: http://askubuntu.com/questions/71103/guest-session-only-shows-background-not-a-complete-desktop

I have the same problem in a fresh install on a new hard disk, I log under Unity 3D OK

when I select a “guest session “I get the background only. With a little guesswork I can select the right end corner menu and close the session

thanks for your bug report. Is that still an issue in Ubuntu 12.04? Can you please test that and let us know?
