FEBRUARY 2020 UPDATE
A major change will hit the reopsitory:
KERNEL: this one is a big change. I've started rewriting the 15kHz patch to make it more flexible, more "kernel compliant" and respectful of resolutions handling. This opens the kernel for easier hacking later, but has a major drawback for people who have an existing rig with groovyarcade: upgrading to 5.5.x means editing /boot/syslinux/syslinux.cfg and manually edit the video=... param. Here is the rule:
- remove c or z, replace it with S
- you must specify if the resolution is interlace b adding an i after the resolution
-> examples:
video=320x240ec becomes video=320x240eS
video=640x480ec becomes video=640x480eiS
See https://github.com/D0023R/linux_kernel_15khz#since-55
feel free to ask any question

Signal-wise, the result is identical to using "native" resolutions, it's absolutely the same thing.

I don't see myself ever using LX, but really glad to read that!

Not trying to convince you, but I'm curious to know why, what you'd expect from an arcade linux distro, and what could make you consider giving a try.
Recapnation:
Here's just a few reasons:
You really need a 15-kHz set-up to properly play some of the best action games for WIN (much like you need another for 31-kHz, but I'll stop there), not to mention some key emulators MAME just can't compete with at the moment and have no LX version (how's Retro Arch on LX?). So there's no point (for now, at least) in messing also with LX for anyone interested in this stuff (and I really see no reason for not being interested if you are in MAME, but maybe that's just me).

Which key emulators are missing ?
Regarding linux mame that can't compete vs win mame, i'm not so sure. Sadly no one with GILT has tested input lag in linux. But although linux seemed to have always been 1 frame behind windows, i think we've found the reason.
Now, a few cons fir linux if you have a good 15k setup (which means Radeon gpu):
- takes less than 10 minutes to install, configure and play your first rom. You can even test without installing
- no need for super resolutions, all mame games are played at native resolution
- no limits on the number of 15k possible resolutions, except if they come from your hardware
- no need to boot in safe mode, tweak anything that is driver related
What one could tell me is that the linux task scheduler is not made for gaming, which can result in worse performance than windows. This has been proved. Nevermind, i can add a real time kernel to linux and test again. But please, no prejudices, just facts. Missing emulator is a fact, mame in linux sounded more like a prejudice.
I'm really not stating that linux is better than windows, i need some true facts that would lead me on how to shrink the gap
