Thanks. https://errors.ubuntu.com/oops/8dffea99-154c-11f0-b404-fa163ec8ca8c is more like what I was expecting; gnome-shell is blocked in some X11 call waiting on a reply from the server that never comes.
The lack of debug symbols means I can't see enough detail. But it looks like the important part is some libmutter function in or after meta_virtual_monitor_set_mode(). That Mutter function is blocked waiting for some libX11 function, and its caller is libglib so the Mutter function might be a callback. -- 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
