GroovyArcade live-CD 2022 (collaborative effort)
Substring:
So your steps show a fundamental difference between the original groovyarcade and my fork : i went the xorg.conf-less way. In 2020, Xorg hardly needs a xorg.conf, it's even not recommended anymore to have one. This also means i'm missing some inputs configuration (like wiimotes), but noone complained so far ;)
Regarding your rig, you shouldn't need the dot clock fix, you gfx card can handle low pixel clocks. Just for a test : you should be able to launch any game from the bare iso once screen autosetup is done, without installing to a HDD. Just follow the autosetup and press a key when necessary, then once in gasetup, just start the first default option. It should launch AM flawlessly, and you can give a go to default roms. They should all work.
I feel more concerned about that game not restoring the default resolution once you've quitted mame. Can you give me its name ?

OK, had some time this morning. I read your post and booted from the USB installer. Here's the steps I took and what I observed:
First screen is split and offset (left side aligns center then wraps around)
Choose 15khz
I press "enter' when the prompt screen appears. In the end, it reads: -Connection DVI-I-1 was selected / The arcade monitor couldn't be natively detected, the output will be forced at boot / Do you want to validate these settings? to which I select YES.
Choose Generic 15khz monitor
Get to gasetup, launch AM
Looks good, launch a game
Black screen/loses any picture
Exiting to AM is also black screen, but i can hear audio
Exiting AM to gasetup restores picture, able to launch AM once again.
Tried multiple games (default roms), all the same result
Changed the monitor to K7000 and 15khz arcade, same result
AM will freeze within a couple of minutes
Is there anything I should be checking with regard to the monitor?
Banane:
Hey Rewind22x, maybe this leads into a wrong direction, but what´s the status of your J-PAC sync light when the screen switches off ?
Out of the sudden I´m having trouble with this ....could be related.

I really need to see your mame.ini, your /var/log/groovy.log, /var/log/Xorg.0.log + a mame log to see what switchres does
Calamity:
@rewind, also post the output of xrandr. That black screen can happen for 2 reasons:
1. You have another output active as primary and GM is sending video to that one. This is likely the case, since you're using a jpac and your analog connection goes undetected.
2. A low dotclock issue
