gnome-shell 20.10 crashes with Wayland

[J-Paul BERARD]

Ubuntu Gnome 20.10 (upgraded from 20.04), 64 bits,Wayland session
AMD CPU Fx
GPU Radeon

Very frequently, Gnome-shell crashes and difficult to understand why or when.

Example : open a Libreoffice Calc file ; export it twice in PDF format on the Desktop. Right-click on this files icons on the desktop to delete them : for the 2nd, the screen becomes black (I can do nothing) and after about 20 s, I get the login screen.
I exported the journal file (attached file) (and the session crashes again) because the system says nothing !

Doesn't happen with X session.

Thank you for taking the time to report this bug and helping to make Ubuntu better. It seems that your bug report is not filed about a specific source package though, rather it is just filed against Ubuntu in general. It is important that bug reports be filed about source packages so that people interested in the package can find the bugs about it. You can find some hints about determining what package your bug might be about at https://wiki.ubuntu.com/Bugs/FindRightPackage. You might also ask for help in the #ubuntu-bugs irc channel on Freenode.

To change the source package that this bug is filed about visit https://bugs.launchpad.net/ubuntu/+bug/1907904/+editstatus and add the package name in the text box next to the word Package.

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.

Hello !

No crash in /var/crash

For Whoopsie, I found several links in the page
https://errors.ubuntu.com/user/39229ebea988d6578bed98d7e18bd96fd9cd523cf89495ed70d4ce4c0f8b7937667368f389be8d8b2588bafc31d1935109305b4abf52dbb724a7cf43c3b425b4

Thanks. Merry Christmas.

Thanks but the last gnome-shell crash on that page was on 2020-05-16. Although that crash was bug 1886059, it may not be the same issue you experience now. So please continue following the steps in comment #3 next time the problem happens.

Thanks for reporting bug 1910254, that one is a duplicate of bug 1898910 for which a fix will soon be released.

Would you like to keep this bug open or mark it also as a duplicate of bug 1898910?

[J-Paul BERARD (arverne)]

I have updated GNOME to 3.38.2 today, by enabling "proposed packages" like explained in bug 1898910.
I will see if that solves the issue.
Thanks.

[J-Paul BERARD (arverne)]

Considered solved and duplicate of bug 1898910 : no crashes for 48 h after update of GNOME by "proposed packages".
Congratulations and thanks because it was really annoying to have a session who crashes at any moment !
