I updated to 18.10 in place. That fixes the problem with the blank screen. Unfortunately the menu to the upper left does not seem to get focus. To logout I go to the upper right and type logout which loads a 'logout app.' I suppose that's a different bug.
Thank you for your help. Please let me know if you would like further testing. I'm working with scripts to install Ubuntu (and Debian) on ZFS root and can load up a fresh install in a little longer than it takes to install using the conventional installer. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1808226 Title: Rotated screen is blank in Wayland sessions [Failed to set CRTC mode 1600x1200: No space left on device] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1808226/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
