Thanks. Unfortunately that log is not helpful because it contains only one boot done in recovery mode with modesetting disabled:
Apr 15 14:33:53 lance-desktop kernel: Command line: BOOT_IMAGE=/boot/vmlinuz-5.0.0-11-generic root=UUID=ddacea78-cdda-4236-94c3-4c4d9d3dad20 ro recovery nomodeset Please reproduce the black screen problem once (ensuring that you are not booting into recovery mode*), then reboot again once, and then run: journalctl -b-1 > prevboot.txt to collect the log of the previous boot which had the problem, and send us the file 'prevboot.txt'. * To ensure you are not booting in recovery mode, as soon as the purple screen appears tap Escape. Then search through the menus and choose a kernel to boot that is not recovery mode. -- 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/1824588 Title: Ubuntu Disco boots to or logs out to black screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1824588/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
