Not a problem on live USB stick I installed from. I booted the live medium for Cosmic, set a password for the live user, created 'anotheruser' from the Settings panel, logged out and back in as the live session user.
Clicked the User Menu -> Live Session User -> Switch User, and I was taken straight to the GDM login screen, where I could switch user to anotheruser. And I was able to switch back and forth between the live user and anotheruser without any issues. An oddity is in the live session the 'Lock screen' icon isn't offered even though the accounts are password-protected - only Switch User is present - which makes me wonder if I'm activating the same code path this way. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1809117 Title: Screen corruption on "Lock Screen" or "Switch User" command To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1809117/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
