Hi, As discussed with duflu on irc, here are the steps I took to reproduce and produce a log:
1. Enable debug in /etc/gdm3/custom.conf 2. Reboot 3. From other laptop; ssh wendigo journalctl -f 4. Intentially login with a faulty password first, which made GDM just prompt as normal 5. Login with the correct password, which caused the purple screen + mouse 6. Copy the log up to this point 7. Press a bunch of ctrl+alt+fn+f-key combos until I got back to login screen 8. Login as normal, ctrl+c the SSH session and scp the file. ** Attachment added: "wendigo journalctl" https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1766137/+attachment/5126446/+files/journalctl -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1766137 Title: [regression] Password accepted but login fails (blank purple screen and mouse pointer only) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1766137/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
