Rotated screen is blank in Wayland sessions [Failed to set CRTC mode 1600x1200: No space left on device]

[HankB]

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.

It sounds like this bug is only affecting "Ubuntu on Wayland" and not "Ubuntu". Is that right?

The error message:

  Failed to set CRTC mode 1600x1200: No space left on device

comes from mutter's eglnative (Wayland) backend, after calling drmModeSetCrtc. So "No space left on device" is an error from the kernel with no further explanation :(

Can you please try logging into "Ubuntu" (the Xorg session), run 'xrandr' and send us the output?

[HankB (hbarta)]

Yes, seems to be related to Wayland.

I have attached xrandr output from an Xorg session.

Thanks!

[Daniel van Vugt (vanvugt)]

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.

[HankB (hbarta)]

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.

Just installed Ubuntu 18.04 LTS on HP EliteBook 8470p. Got the same error on fresh boot. It probebly was because of ubuntu now uses screen rotation gyro(?) and started to rotate screen. Anyway, to steps to fix.

1. CTRL+ALT+F2 to get into console.
2. Login
3. Do https://linuxconfig.org/how-to-disable-wayland-and-enable-xorg-display-server-on-ubuntu-18-04-bionic-beaver-linux
4. Do https://askubuntu.com/questions/1035209/how-to-turn-off-screen-rotation-in-ubuntu-18-04-lts
