Bug description:
[ Impact ]
Mutter autopkgtests are failing if a GPU exists but is not accessible.
Surprisingly this only just started becoming a problem recently:
2730s # libmutter-MESSAGE: Running Mutter Test (using mutter 42.9) as a
Wayland display server
2730s libmutter-Message: 13:24:23.050: Running Mutter Test (using mutter

I can also reproduce it on amd64 using a second user account that
doesn't have access to /dev/dri/*
Previous successful builds look like they worked only because there
was no GPU to fail to open(?)
[ Test case ]
Autopkgtests must not fail when building for jammy-proposed
[ Regression potential ]
Mutter may fail to initialize on some GPU types.
