Bug#908808: gdm3: GDM3 crashes with nvidia-driver installed.

[Different55]

Package: gdm3
Version: 3.28.2-4
Severity: important
Tags: upstream

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?
   * What exactly did you do (or not do) that was effective (or
     ineffective)?
   * What was the outcome of this action?
   * What outcome did you expect instead?

Install vanilla Debian Testing/Sid, update, reboot, install nvidia-driver,
reboot, GDM3 now glitches out and crashes in a loop, making it hard to switch
to a TTY or do much of anything.

Turns out it's because GDM3 is trying to start with Wayland, even on the nvidia
drivers where Wayland is known not to work.

GDM3 should not try Wayland when it's known not to work.

This bug was already fixed upstream in 3.29.92.
I wasn't sure whether to report it or not but since the reportbug tool said to
check only against what was in experimental (which is 3.29.91-2), I'm going to
err on the side of caution here and report it.
