gnome-shell --replace does not work: Can't initialize KMS backend: Could not get session ID: No such file or directory

I don't know anything about gnome internals, but with trying to strace, I see this:

getpeername(2, 0x7ffec62742e0, 0x7ffec62742dc) = -1 ENOTSOCK (Socket operation on non-socket)

which is odd, since stderr is not a socket usually, indeed ...

Other than that, the mentioned error message can be found here, after trying to "apt source" some gnome specific packages:

mutter-3.24.1/src/backends/native/meta-launcher.c

in function get_session_proxy()

Though for sure, I have exactly zero knowledge about these :-/

@Daniel

this is what i get now with fresh artful & bionic installs: i can only login with Xorg, when sometimes ago, with the same hardware & a zesty -> artful dist-upgrade, wayland was used without problem.

So is mutter faulty here, or ubuntu-drivers-common or libinput, as the system choose the fallback way (which is wrong: skylake gt2 igp (only))

But setting to 'low' priority might be set higher as wayland is the default now.

 sudo dbus-run-session -- gnome-shell --display-server --wayland

(gnome-shell:3724): mutter-WARNING **: Can't initialize KMS backend: Could not get session ID: No such file or directory

Status changed to 'Confirmed' because the bug affects multiple users.

Is this bug still present in the final release of 18.04 or later? The 'bionic' tag was added in 2017.
