Getting 240p on 31KHz CRT Monitor with MME4CRT

[daifuku74]

Hi everyone,

I installed Mubuntu-MME4CRT-desktop-amd64-v1.iso on my Core2Quad PC
and it seems great.

I'm using it with a CRT 19" Trinitron PC Monitor (VGA)
So I launched the "31K install" from the "start menu" and "games", and then rebooted and launched Retroarch.
Once inside if I try loading a rom it works but does not switch to low resolutions.

Myabe I connect the monitor at the wrong timing?
or I need a tool similar to VMM for Linux to generate resolutions first??

Is there a tutorial or something? 

Thank you very much
