m3129 resolution questions/problems?

[emuola]

I set the grub options as follows (thanks Calamity):

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

but my shiny m3129 goes psycho when the boot process begins, the relay clicks like crazy, because the signal is something incompatible. In the advmenu (set to 640 x 480) monitor woks fine.

How Can I force the boot to vga, if/when the line above does not help?

Some questions, that I don't understand:

1. Should the image "fill the whole" screen area when doing 640 x 480 in Advancemenu?
2. I ask the 1. question, because if I set the monitor so (640 x 480 fills the whole screen), All the 320 x nnn games won't fit the screen vertically --> the image is wayy too high vertically. Wrong modeline(s)?
3. When a 320 x nnn game launches, should it be automatically in the center (horizontally)? Because, now it's not...

Sorry, never had a tri-mode before

Hi emuola,

There's nothing we can do about the boot, the kernel line in grub only has effect after a few seconds, so the first part of the boot is going to be out of range whatever we do. My advice, if you don't like what you hear, is to only turn on your monitor after a while, when you're sure it's already outputting the right frequency. This is what I do for my tri-sync BTW.

I've dug about the source of the m3129 presets, it turns out those were just testing presets and never got properly figured out because the user's monitor actually broke!:

I don't mean that those settings are potentially dangerous, they actually look reasonable, I just want to warn you about that specific model so you are careful.

- GM can make all your resolutions to almost fit perfectly on the HORIZONTAL, once you find your custom specs.
- No software can control the VERTICAL size of a resolution on a CRT monitor, you need to adjust it physically (potentiometers, service menu, etc.).

Ok, I'll have to figure out a convenient way to add a power switch for the monitor The preset might be something pretty much ok, but I'll be cautious.

Yes, that's what I figured It seems that now there's something wrong with the modes/settings, because all the 320 x nnn games fit nicely on the screen, but are ~ 1/10 of the screen to the right from the center.

These are the presets for your monitor, as they are defined now:

      crt_range0 15250-16500, 40-80, 2.187, 4.688, 6.719, 0.190, 0.191, 1.018, 1, 1, 224, 288, 448, 576
      crt_range1 23900-24420, 40-80, 2.910, 3.000, 4.440, 0.451, 0.164, 1.048, 1, 1, 320, 384, 0, 0
      crt_range2 31000-32000, 40-80, 0.636, 3.813, 1.906, 0.318, 0.064, 1.048, 1, 1, 480, 512, 0, 0

Set the -monitor option to 'custom'. Then change the values in black until you find the right spot. To shift the picture left, try increasing the first value and decreasing the second, e.g. 3.187, 4.688, 5.719.

Thanks again Calamity, you rule  Now it's almost perfect. Games look absolutely brilliant  The only complaint would be the slight "old skool vertical shake" when I'm looking at the advmenu. I guess it's got something to do with the vertical refresh rate Advmenu uses (it beng very low for "text and images" kinda thing). I did not find any place to define it.

Anyways, looking great (literally)
