[Bug 1791054] Re: Ubuntu 18.04.1 becomes unresponsive after Logout or Resume
For a while Logout/Resume/Switch User worked fine with Wayland (as well as with Xorg when I cross-checked it). But finally, when I tried "Switch User" again with Wayland, I got stuck on the Login-Page of the current user - it was not possible to get the page displaying all available users. To be sure I made no mistake I checked: echo $XDG_SESSION_TYPE wayland The first line in the attached syslog should be the moment when I clicked "Switch User". The last line seems to be the moment when I logged in as original user again. Both lines contain the same error message. ** Attachment added: "syslog_Wayland_UserSwitch" https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1791054/+attachment/5186149/+files/syslog_Wayland_UserSwitch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1791054 Title: Ubuntu 18.04.1 becomes unresponsive after Logout or Resume To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1791054/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

That might be a Xorg-specific problem. If you log into "Ubuntu on Wayland", does that work around it? ** Changed in: gdm3 (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1791054 Title: Ubuntu 18.04.1 becomes unresponsive after Logout or Resume To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1791054/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
