Looking at https://errors.ubuntu.com/oops/b3d821a0-143f-11f0-8694-fa163ec44ecd from comment #64 it appears I gave bad advice with "USR1". We need a signal whose default action is to dump core, so please try this instead next time the problem happens:
Switch to a VT and the force gnome-shell to dump core: killall -ABRT gnome-shell Then hopefully we will get a crash report created in /var/crash/ -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2089709 Title: Ubuntu 24.04 (X11) sometimes logs in to a black screen with only an X cursor To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/2089709/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
