Hi rewind22x,
With regards to the black screen after launching MAME, try setting "dotclock_min 25.0" in mame.ini. This will force super resolutions and probably fix the issue.
Wifi support in GA has always been a problem. Hopefully this will be addressed in future versions.

Hey rewind22x,
Thank you for sharing your experience with us.
Can you give more details about your rig ? That would help diagnose resolutions issue + which config you chose at boot (15/25/31/svga). 2020.1 had some bugs when applying autosetup parameters.
Regarding wifi, yeah it's a real problem for now. Forget any security stronger than WPA, the default network manager can't handle WPA2 or later. I will explore other alternatives with one main requirement : hase a nice GUI for people who like the text setup, and easily editable config files that allow me to script configuration. That's a major feature that will take much time to evaluate and test all network managers with their possible GUIs.

GA 2020.2
It's been a week or so since I set things up, so my memory is probaby off. But on first boot, I selected 15khz, got into the setup. It did the autodetect, found the display (DVI > VGA > JPAC > Monitor. Configured the monitor to Wells Gardner K7000, horizontal, 4:3.
I tried the dotclock settings (both manually editing the mame.ini and using the option in gasetup) but no luck. The screen goes completely black, like it loses power. I just tap ESC until I hear the AttractMode music, then hit ESC again, press the down arrow and then Enter. That gets me to gasetup, which activates the monitor and then I relaunch AttractMode.
I will try installing from scratch tomorrow. The cab is at work, kind of a 'employer sponsored' pet-project. We had a Galaga Arcade1Up cab that we gave away at the company xmas party. It was set up in front of my office door and was pretty popular. So I convinced my boss we needed a full size cab in the office. We found someone selling a Marvel vs Capcom cab on craigslist and bought it. The cab itself is kinda beat, but after some TLC, should look pretty good. I got it working with Retro-Pie + a Rpi 3+ but wanted something more powerful and reliable.
If you guys have any other ideas, I'd be glad to try them. I do appreciate the work being put into this project and am fully aware it's a work in progress. I've had 2020.1 running on my arcade1up cab at home (LCD) and it's been rock solid... except for the black-screen issue. The joysticks/buttons will not wake it up. A keyboard press does. So I tell my kids to just tap the Select button until it launches a game and then the screen appears and they can then decide to play or exit and pick another game. The JPAC shows up as a keyboard, so no issues with waking on the full size cab here at the office. Half tempted to just use an iPac2 in the arcade 1up, but at this point, I'm done putting more money into it... until I'm not. lol

This setup should just work out of the box, without even forcing horizontal or 4:3.
Check mame.ini and report the monitor parameter, it could have gone wrong, some older parts of gasetup (the text based tool to configure) may interfere with code I've added. Mame's log (it's up to you to manually start mame, check Calamity's signature) could help understanding which screen resolution was selected, and check if it fits in your screen specs.
Now regarding screen blanking ... So far I couldn't remove it. The Xorg options I tried didn't change a thing, I should dig this further.
Now thanks to your feedback, I could set some priorities on my todo ;) I'm on holidays atm, will get back into coding Sunday ;)

Crap, I spaced an important detail.
You are right when you said it worked out of the box. I just checked the cab out over my lunch break. I did the 'Force XORG' fix, which borked getting into AttractMode. Then I went through the Monitor/Orientation/Aspect Ratio setup. Went back into the fixes and forced the "dot_clock" fix, along withe the "screen tearing" fix. Fired up AttractMode and got it back. On a whim, i opened a game and it showed up. Couldn't believe it. I then fired up another. It had vertical sync issues, but it still appeared. Another issue appeared though, upon game exit, AttractMode was half its horizontal width and forced to the left of the screen. Exiting to gasetup and reopening AttractMode fixes that. I thought about a plugin that needed to be enabled to restore AttractMode after a game is run that changes the resolution, so I opened the settings and then AttractMode froze. And then my memory jogged. I remember having this issue with AttractMode freezing. I did some research and fixed it by setting a progressive video resolution. But then opening MAME games resulted in a completely black screen. I never thought to see the link.
So anyway, I'll do a fresh install tomorrow (if i have the usual sleepy Friday at work) and keep track of what I'm seeing, as I've probably jacked things to a point where I'm not sure what's broken or whats fixed. Thanks again for the help.
