After leaving my PC alone for a few minutes I found it at the login window and the session crashed.
Attached is the crash log. If it can be useful, I also have a 145Mb Xwayland core dump from the same crash ** Attachment added: "_usr_bin_Xwayland.1000.crash" https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1756092/+attachment/5091626/+files/_usr_bin_Xwayland.1000.crash ** Changed in: gdm3 (Ubuntu) Status: Incomplete => Confirmed ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1756092 Title: Screen freeze for some time when unlocking To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1756092/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
