Bug description:
I have upstreamed a GNOME/Wayland desktop freeze fix in:
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1209 (master)
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1215 (3.36 branch)
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1216 (3.34 branch)
I diagnosed the freeze on Mutter 3.34 Ubuntu 19.10 flavour first, with
DisplayLink hardware. Any DRM driver that may temporarily fail
drmModePageFlip() calls might trigger this.
I triggered the freeze particularly by trying to make a DisplayLink
output the only active output via GNOME display settings. Other
triggers are possible.
This fix may help with
https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1853357 but I
don't know for sure.
