The attached logs don't appear to be useful. They show both a successful boot and recovery mode boots.
Please: 1. Run the following command to automatically gather more info: apport-collect 1904474 2. Reproduce a failed boot again, wait for a minute or so, then reboot into recovery mode and run: journalctl -b-1 > prevboot.txt and attach the resulting text file here. 3. In future report bugs using the 'ubuntu-bug' command. ** Package changed: ubuntu => gnome-shell (Ubuntu) ** Changed in: gnome-shell (Ubuntu) Status: New => Incomplete -- 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/1904474 Title: Black/purple screen after booting Ubuntu To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1904474/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
