Thanks. If you can then please try the latest stable release of Gnome Shell by installing Ubuntu 18.10. But only if it is convenient.
If you don't or can't find that the problem is fixed in a later release already then please report it to the developers here: https://gitlab.gnome.org/GNOME/mutter/issues with details of the symptoms and the error message. And then tell us the new bug ID. ** Summary changed: - rotated screen is blank + Rotated screen is blank in Wayland sessions [Failed to set CRTC mode 1600x1200: No space left on device] -- 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/1808226 Title: Rotated screen is blank in Wayland sessions [Failed to set CRTC mode 1600x1200: No space left on device] Status in gnome-shell package in Ubuntu: Incomplete Bug description: Using "ubuntu-gnome-desktop" ("vanilla-gnome-desktop" also installed) with external 1600x1200 monitor rotated 90 deg.
