Method used to collect this info: (1) Fresh installed 20190413.2 choosing not to auto-login. (2) Rebooted after install and surprisingly gdm3 appeared as it should so I booted to desktop and just rebooted. (3) That reboot failed as had been the previous case - just a black screen, totally unresponsive. (4) Performed a hard reboot with the reset button on the PC, entered recovery from grub menu, then installed lightdm, and rebooted. (5) Collected info as instructed.
So there are a total of 3 boots. The first was successful - no problems. The second booted to a black screen instead of displaying gdm3 screen. Third boot was performed using lightdm. ** Attachment added: "prevboot.txt" https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1824588/+attachment/5256045/+files/prevboot.txt -- 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
