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. Run these commands:
    journalctl -b0 > journal.txt
    journalctl -b-1 > prevjournal.txt
and attach the resulting text files here.

2. 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.

3. If step 2 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.

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.

I am seeing three different gnome-shell crashes here:

 * Signal 6: Assertion in meta_window_get_work_area_for_logical_monitor
 * Signal 11: Reason unknown. No crash report.
 * Shutdown due to Xwayland crashing.

Also the only reason for Xwayland crashing I can see is related to nouveau. So please use the 'Additional Drivers' app to install an official Nvidia driver. Though that will force you to use Xorg instead of Wayland.

Thank you for taking the time to report this bug and helping to make Ubuntu better. This particular bug has already been reported and is a duplicate of bug 2050865, so it is being marked as such. Please look at the other bug report to see if there is any missing information that you can provide, or to see if there is a workaround for the bug. Additionally, any further discussion regarding the bug should occur in the other report. Feel free to continue to report any other bugs you may find.

[Daniel van Vugt (vanvugt)]

If you can find any crash files from Xwayland in /var/crash then please open a new bug for that.
