Comment 8 for bug 1882102

You are using multi user target because you like to or also having some kind of problems?

If I use (which means removing the if else)
exec /usr/libexec/gnome-session-binary --systemd "$@"
the result is the same. Still the same message for missing permission.

And with
exec /usr/libexec/gnome-session-binary --builtin "$@"
the result is identical.

I thought maybe it's good to sort out this error first and if there are no problems without starting GUI without root rights than maybe a second bug report for boot to gui. But I can also open another bug report now. I'm not sure if this bugs / problems are connected in any way or not.

With 18.04 I did not have this kind of errors on both machines. The funny thing is: On my Raspberry Pi 4b it is working from start (ok, this is a special distribution for special hardware so it should run).
