Thanks. I uninstalled LIRC, just to be on the safe side. Orca is necessary for my using the computer. I uncommented the line #WaylandEnable=false and rebooted. The problem still persists.
Then, without logging in graphically, I switched to tty3 (Ctrl+Alt+F3). Logged in, executed a single command "who", then exited using Ctrl+D. GDM (or Gnome-shell?) shows the time and date. The mouse pointer sits in the center of the screen and can no longer move. The keyboard no longer does anything, except Ctrl+Alt+F1. When I do that, the screen goes black and the system freezes totally - or at least all inputs like keyboard, mouse and braille display do. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gdm3 in Ubuntu. https://bugs.launchpad.net/bugs/1764643 Title: Logout after console use freezes GUI To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1764643/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
