Public bug reported:
Using "ubuntu-gnome-desktop" ("vanilla-gnome-desktop" also installed)
with external 1600x1200 monitor rotated 90 deg. Monitor connected via
HDMI and using Inel i915 driver.
1) Login to "Ubuntu" session. Use Settings -> Display to rotate monitor 90 deg
left. Accept new settings. Logout.
2) Login to "Ubuntu on Wayland" External monitor gets no signal.
Following line at the end of 'dmesg' output seems to relate to the issue:
Dec 12 14:37:46 saugage gnome-shell[6125]: Failed to set CRTC mode 1600x1200:
No space left on device
Searching for this message reveals several reports of Gnome Shell
crashing at this point. It does not crash for me but the external
monitor remains unusable.
