Hi all. I noticed that running the current demo gallery app on the 7.1 release of Torizon for the colibri-imx8 fails with the following log:

Switching VT tty1 to text mode if currently in graphics mode
Switching VT mode of /dev/tty1 to text
Switching to VT 7
SoC is: 'i.MX8QXP'

Removing previously created '.X*-lock' entries under /tmp before starting Weston. Pass 'IGNORE_X_LOCKS=1' environment variable to Weston container to disable this behavior.

Looking at the current docs, I modified the appropriate file as shown in this PR.

I think we need to do something a bit more rigorous here to make sure we catch these things early.

Geting proper automation is certainly one aspect. Ideally we would test all of these apps across all the modules and on at least the latest 2 Torizon OS releases.

It's not clear if we need to have different versions of these apps for different OS versions or how best to handle the matrix of board/demo app/OS version combinations.

NOTE: DO NOT MERGE THIS AS IS. THIS DOES WORK BUT NEEDS MORE THOUGHT BEFORE MERGING.

At a minimum this new version of the docker-compose file will need to be canonicalized.
