The crash history supports the theory that this was: https://gitlab.freedesktop.org/xorg/lib/libx11/-/merge_requests/34
because that fix appeared in libx11 1.7.0 during the hirsute development cycle. So usually at this point I would recommend trying that fix. However, despite being the top gnome-shell crasher on errors.ubuntu.com this bug page is so quiet that I'm not sure we have enough people engaged to be able to test any potential fix. ** Also affects: libx11 (Ubuntu) Importance: Undecided Status: New ** Changed in: libx11 (Ubuntu) Assignee: (unassigned) => Daniel van Vugt (vanvugt) ** Changed in: libx11 (Ubuntu) Status: New => Fix Released ** Changed in: gnome-shell (Ubuntu) Status: Incomplete => Invalid ** Changed in: mutter (Ubuntu) Status: Incomplete => Invalid ** Also affects: libx11 (Ubuntu Focal) Importance: Undecided Status: New ** Also affects: mutter (Ubuntu Focal) Importance: Undecided Status: New ** Also affects: gnome-shell (Ubuntu Focal) Importance: Undecided Status: New ** Changed in: libx11 (Ubuntu Focal) Assignee: (unassigned) => Daniel van Vugt (vanvugt) ** Changed in: libx11 (Ubuntu Focal) Status: New => Confirmed ** Changed in: libx11 (Ubuntu) Importance: Undecided => High ** Changed in: libx11 (Ubuntu Focal) Importance: Undecided => High ** No longer affects: gnome-shell (Ubuntu Focal) ** No longer affects: mutter (Ubuntu Focal) -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1886059 Title: gnome-shell crashed with assertion failure "!xcb_xlib_threads_sequence_lost" [xcb_io.c:260] To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-shell/+bug/1886059/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
