Unfortunately, according to this post by Calamity (and my own personal experience), the ATI X1300 is compatible with low dot-clocks making it unsuitable.

So, not all ATI cards are compatible. Neither are all Arcade VGA cards. Check the guide here for more info.

Do you have any other contenders laying around?

Hi,
Thx for your answer, but you are talking about Calamity drivers, running on windows, and I'm a talking about the linux distrib.
Then if the X1300 is not supported.

Which card support 15khz, with the linux distrib?

In Linux
 anything besides the X8xx series should work

Hi,

Does this mean that every PCIE Ati should work but the X8xx?

Hi processor,

The GroovyArcade distro is meant for ATI cards only.

Now, what we know from Windows is that from the X series, only the lower ones work fine (X300, X600,...). The others (X1300, etc.) can't do low dotclocks. HD 2xxx and HD 3xxx have the same problem. This doesn't mean that they don't work: you can just setup GroovyMAME to use higher dotclocks and it will duplicate xres in order to do that, but that's kind of problematic with other emulators.

As this seems to be driver related, and not a hardware issue, in Linux, they might work just fine indeed. The problem is that we don't have information about it. It would be highly appreciated that someone with a bunch of different ATI cards tried the GroovyArcade distro and did the right tests to determine which ones are fully compatible or not. I've tested it myself with R 9250 and HD 4350 and it worked great with those.

Mmmhhh...Are you sure?
For what I saw GroovyArcade try to determine the correct video driver for the X server and force it to 15KHz through kms (aka 15KHz kernel patches).
So since the videocard is supported by the open video drivers and these drivers use kms for image rendering, then the videocard is supported.
Obviously the start point always is having good drivers for that videocard.


I've tested it myself with R 9250 and HD 4350 and it worked great with those.
I have tested it with a R9200 and a HD5450; both works well.

Yes that's true. And the only drivers that have been tested succesfully are the ATI ones, that's what I meant. Again, if someone had the time and energies to test this with nvidia cards and report back it would be highly appreciated.
