I am using Pentium IV 2,4 GHz, Ati Radeon X800 Pro and an arcade monitor. I yesterday tried the older version 1.500 with the Voodoo3 and Matrox G400 I used to use with AdvanceMame DOS. Those cards didn't work. Fortunately I found an old Radeon which seems to work better. So far with the new version, I have been able to see LiveCD booting and AdvanceMenu in 15 KHz glory, but games themselves are using wrong garbled display mode.
I will keep tinkering with the software, I don't have a spare hard disk atm, but I will try to improvise with a USB stick.
I really hope this project will stay updated. I try to contribute something myself too. Bug reports and feature requests if nothing else.

Possibly set the window manager to use fvwm or lxde, then from a terminal run groovymame <rom> -verbose -md 4 That output might show something interesting about the issue, I'm guessing it's a mismatch between monitor setting to groovymame and actual monitor. See what monitor you've got set in mame.ini, check if it's the same as in switchres.conf since they should be the same. What kind of arcade monitor is it, what khz and hz ranges can it do? There's a 'cga' monitor option, a generic one, and h9110 one, all slightly different sections of the 15khz range from low-med-higher (or 15.2 - 16.5 or something). Also trying `xrandr -q` in the terminal in fvwm/lxde might be interesting, double check you've got the right output as VGA-0 or DVI-0. See what mame.ini has for the connector, and if it's really the right connector, maybe even try the other connector on the card and bootup with that one. One possibility is the mame.ini isn't getting setup properly with these settings. If you're able to get logs from running groovymame in verbose mode, post them here if possible too.
I must admit though the ATI X800 might be the issue, I have an X850 actually and I had issues with it getting 15khz properly in all modes, never was sure about if just my model (since it's a special Crossfire one).

Thanks for a quick reply. I will those things out. In the meantime, do you have info about the cards that should work easily? I can get a specific one for my cab, if needed. I have bunch of old ones I used to collect for AdvanceMame: Matrox, Ati (pre-Radeon), S3 and some Voodoo3 and nVidias for example, but I guess they are too old. To complicate things, the system I use uses AGP.

The ATI HD4xxx cards are good, ATI HD5xxx cards good but more risky, I have a hd4350 and hd5450 and both work great. The AVGA3000 is good, I use one, get the bios bootup, the older AVGA 92x0 cards are good, and the ATI equivalents just as good but no bios bootup. I would stay away from any of the cards that start with X, seem to have issues. The older HD2600 ATI cards work ok. Cheapest of course is probably the HD4350 or HD5450 but I'm not fully certain of AGP options for those, but are the most well tested choices.
I'm guessing the older cards, or ones you have, mostly will not be able to do the 15khz resolutions. One of my plans is to go through different video cards, look through the Linux kernel code for them, figure out what state they're in and if possible make them 15khz capable or at least document which ones can actually do the same as the ATI Radeon ones. Unfortunately the ATI development for general modeline switching and vsync/page flipping is really ahead from what I can tell, but would really be nice if I discovered other drivers were there too and I just haven't realized it. I might look into that more in the next few days, I'm curious now and sounds like a good thing, have been basically under the assumption everyone used an ATI card or Nvidia but the Nvidia ones with the nouvue driver are probably not "there" yet in supporting all we need to do 15khz modelines. Also one other possible issue with an Nvidia card, or others, is that connector name needed in Groovymame. It may need to be something odd like 'default' for those, using xrandr -q will show you what the driver decided to call the output connectors, and all the different brands have chosen different names unfortunately.

Thanks for the info. I will hunt down an ATI card. It really isn't a problem, just get a card that works and me done with it. I am so happy that I get the suitable software for my cabinet that supports new Mame version.
The monitor I am using is Wells Gardner K7000.
Specs:
Horizontal scan: 15.1 KHz - 16.8 KHz
Vertical scan: 47 Hz - 63 Hz
I have mostly used the 1. CGA, also tested the second fixed frequency CGA and H9110. I am also using JPAC which should not pass any frequencies much above and below 15 KHz, standard 31 KHz modes also show, but with double image. As far as I can tell the output for games looks like output with Advancemame when the video card was pressed to too low pixelclock value. So it might well be a problem with my video card.

Sounds good, excited to hear back your results, does sound like the video card, thanks for testing.
