[Desktop-packages] [Bug 1965639] Re: purple screen after login using fingerprint
Given we don't see "GNOME Shell started" in that log file it seems gnome-shell probably isn't to blame here, so unassigning. ** No longer affects: gnome-shell (Ubuntu) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1965639 Title: purple screen after login using fingerprint Status in gdm3 package in Ubuntu: New Bug description: I updated the machine yesterday, and additionally added the fingerprint to pam using pam-auth-update.

Thanks for the bug report. Next time the screen stays purple, please: 1. Wait 10 seconds. 2. Reboot and login with password. 3. Run: journalctl -b-1 > prevboot.txt 4. Attach the resulting text file here. 5. Look in /var/crash for crash files and if found run: ubuntu-bug YOURFILE.crash Then tell us the ID of the newly-created bug. 6. If step 5 failed then look at https://errors.ubuntu.com/user/ID where ID is the content of file /var/lib/whoopsie/whoopsie-id on the machine. Do you find any links to recent problems on that page? If so then please send the links to us. ** Package changed: xorg (Ubuntu) => gnome-shell (Ubuntu) ** Changed in: gnome-shell (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1965639 Title: purple screen after login using fingerprint Status in gnome-shell package in Ubuntu: Incomplete Bug description: I updated the machine yesterday, and additionally added the fingerprint to pam using pam-auth-update.
