Daniel, I disagree. This bug is actually about the fact that the test
crafted in /lib/udev/rules.d/61-gdm.rules doesn't parse as expected in
udev. We also should probably file a bug report against upstream udev as
the changes added to support escaped quotes in #6890 aren't robust
enough.

I'm not totally sure we need this bug. The problem with Wayland sessions
missing on Nvidia is tracked in bug 1968929. And the use of
NVIDIA_PRESERVE_VIDEO_MEMORY_ALLOCATIONS should be tracked in bug
1876632. So essentially this bug is just pointing out that we haven't
fixed bug 1876632 yet.

Note that I stumbled onto the above fix after noticing the example shown
for the udev escaped quoting support showed an example with double
quotes surrounded by single quotes which in turn surrounded escaped
double quotes...
I have found that current /lib/udev/rules.d/61-gdm.rules can be fixed by
swapping the order of the single and escaped double quotes from...
IMPORT{program}="/bin/sh -c \"sed -e 's/: /=/g' -e
's/\([^[:upper:]]\)\([[:upper:]]\)/\1_\2/g' -e 's/[[:lower:]]/\U&/g' -e
's/^/NVIDIA_/'
I am wondering if the use of escaped quotes in the failing rule of
/lib/udev/rules.d/61-gdm.rules is really being honored. There don't seem
to be any other examples of deployed udev rules which actually use such
escaped quotes.
