Comment 68 for bug 1951491

@Akkana. My suspicion from digging around is that the problem happens
during login, not session start. Certain steps in the sessiond login
process need to be invoked for the session bus to work correctly. You will
see from other reports that this issue is with the dbus session bus not
being set up correctly. The report about cgroups is a consequence of that.
The workarounds prove this. When I looked into the session start up
process, the problem occurred before session start. systemd has
documentation on what the login needs to do, and I don't think this is
being followed when this problem occurs. I therefore think this is not
about the sessions, but the login process. It's why I wondered if you were
using a modern login manager (such as gdm3) because gdm3 is compliant with
systemd's requirements.
You could dp

echo $DBUS_SESSION_BUS_ADDRESS

from your console before you do startx, and see if it is valid. I'm going
to guess that it is not. When I spent some time looking at this a few
months ago, I had the impression that this variable needs to be set
correctly before the gui session starts.
