Bug#905363: fails to start on rotated screen

Package: mutter
Version: 3.28.3-1
Severity: important
Tags: patch

On a device with rotated screen, gdm3 fails to start.
Journalctl shows many lines:

    Failed to set CRTC mode 1200x1920: No space left on device

Searxing the message leads to

I tested the patch on the Debian package and it seems to work
well on my machine. Please consider applying it. Thanks!
