A few questions about GroovyArcade

[emuola]

Finally ordered the 25" Makvision tri-mode for my Mame cabinet (based on a 1997 Gaelco Surf Planet). I've also built a "new" computer for the cabinet:

C2D E6600 (2.4 Ghz)
2 GB ram
60 Gb ssd
Ati X600 (to get those pixel perfect modes)
 
The monitor should arrive in about a week. As I installed GA with a standard svga lcd I presume I have to change the video settings *before* I hook up the Makvision, right?

Now the question: What video mode/preset I should choose from the GA setup menu? The vga (31 khz)? I don't want to bust the monitor on the first boot 

Another one: What monitor preset (from the thread in this forum) should I use? The 29" Makvision one?

I'd really appreciate your help as always. I'm feeling so anxious about the Makvision and stuff

Hi emuola,

If you installed the GA system using the svga option then your grub setup will need to be manually edited in order to connect an arcade monitor. This is a limitation of the setup program indeed.

So, go to /boot/grub and edit this line in grub.conf:

kernel /vmlinuz-linux root=/dev/disk/by-label/GA quiet splash video=VGA-1:640x480ec vga=785

This ensures your system will boot in a safe 15 kHz mode.

However, you will also need to change the x windows resolution, but this needs to be done with your arcade monitor already connected. In order to do this, make sure to have your system already configured with AdvMenu as your frontend, so it will boot into the frontend, not LXDE. Then you can easily go back to gasetup pressing escape. Notice that your monitor will be out of range until you press escape! So you may want to turn your monitor off after you see the boot logo and turn it on after you press escape.

Then in gasetup just set the video system to something like H9110. This will be used from now on for AdvMenu and LXDE. Anyway, the valid video options for GroovyMAME will be picked from mame.ini, so make sure to edit mame.ini with your monitor settings.

Thank you so much Calamity  I guess I'll just have to generate the modelines and I'm pretty much good to go
