[Bug 2016193] Re: "switch to" a new user immediately aborts, returns to previous user's session

[Daniel van Vugt]

This looks exactly like I would expect:

1. Xorg fails to start in the same way as bug 2015386:

   Apr 13 23:35:23 nvidia-dgx-station-c25989 systemd[3916]: Condition
check resulted in GNOME Shell on X11 being skipped.

2. Wayland fails to start because the server driver doesn't support it:

   Apr 13 23:35:23 nvidia-dgx-station-c25989 gnome-shell[4072]: Failed
to setup: No GPUs found

So this is useful information. It shows:

1. There is a common issue between bug 2015386 and bug 2016193 where
systemd can't start Xorg. It's not even trying so this seems like a
systemd/environment issue.

2. The crashes in bug 2016193 are Wayland-specific (using NVIDIA desktop
drivers). I suspect the customer isn't affected by that.

  I'm using the nvidia 525-server drivers.

  When I create a new user, then attempt to "switch to" that user from
  another user's GNOME session, the new session immediately aborts and
  returns me to the original user's session.
