Switching to console and back crashes session

[Gonçalo Marrafa]

I have a laptop with an external monitor connected to it. When I log in my setup is to use only the external monitor. If I, then, switch to a console and try to switch back to my X session or to the GDM login screen, my logged in session crashes.

Thank you for taking the time to report this bug and helping to make Ubuntu better. It sounds like some part of the system has crashed. To help us find the cause of the crash please follow these steps:

1. Look in /var/crash for crash files and if found run:
    ubuntu-bug YOURFILE.crash
Then tell us the ID of the newly-created bug.

2. If step 1 failed then look at https://errors.ubuntu.com/user/ID where ID is the content of file /var/lib/whoopsie/whoopsie-id on the machine. Do you find any links to recent problems on that page? If so then please send the links to us.

3. If step 2 also failed then apply the workaround from bug 994921, reboot, reproduce the crash, and retry step 1.

Please take care to avoid attaching .crash files to bugs as we are unable to process them as file attachments. It would also be a security risk for yourself.

Thanks for your reply. I've followed the step you recommended to submit a
new bug report.
