42.0-1ubuntu4 blocks usage of Wayland on GTX 1050 graphics card

[Jack Howarth]

Like the previous proposed 42.0-1ubuntu3 packaging of gdm3, the proposed 42.0-1ubuntu4 prevents Wayland from being used on a X570 UD v1.1 motherboard with 5600X processor and Nvidia GTX 1050 graphics card. This proposed change in the gdm3 should be considered a blocker as it defeats the upgrade to using Wayland in 20.04 LTS.

Sorry, there are issues with the Nvidia drivers when used on Wayland.

I'm marking this a duplicate of https://launchpad.net/bugs/1968929 since there is more detail there and it was filed earlier.

I am able to get Wayland back under gdm3 42.0-1ubuntu4 by commenting out the following two new lines that were added to /lib/udev/rules.d/61-gdm.rules

IMPORT{program}="/bin/sh -c \"sed -e 's/: /=/g' -e 's/\([^[:upper:]]\)\([[:upper:]]\)/\1_\2/g' -e 's/[[:lower:]]/\U&/g' -e 's/^/NVIDIA_/' /proc/driver/nvidia/params\""
ENV{NVIDIA_PRESERVE_VIDEO_MEMORY_ALLOCATIONS}!="1", GOTO="gdm_disable_wayland"

So this is the failing test.
