On Ubuntu 17.10...

TEST 1 - NO ISSUE:

1. Set onboard graphics as primary in BIOS.
2. Logged into Ubuntu.
3. Everything was fine.
4. Restarted machine.

TEST 2 - ISSUE:

1. Set GeForce GTX 670 in BIOS.
2. Logged into Ubuntu 17.10.
3. Surprisingly, I was given option of "GNOME" or "GNOME Xorg" in GDM.
   (Note: GNOME == Wayland)
4. Selected GNOME on GDM
5. Logged into Ubuntu.
6. Received this error.

7. Checked which display server is in use:
     $ echo $XDG_SESSION_TYPE
     x11
   (Note: x11 == Xorg, non-Wayland)
   This makes sense because Ubuntu defaults to Xorg for Nvidia cards.

QUESTIONS:

1. Perhaps unrelated, but why is GDM even presenting me with a Wayland option when the graphics card is Nvidia?

2. Does this bug occur whenever Ubuntu decide to chose an Xorg session over a Wayland session? (I see this bug is pretty old, pre-Wayland, but thought it's worth asking).
