Help with xorg.conf editing for arcade monitor friendly resolutions
 
Would anyone happen to how to put the specs of a Makvision 2929D Arcade Monitor with Arcade VGA Video card into xorg.conf in Linux so I can change boot video resolution? The xorg.conf file is blank, so I'm not sure what to enter.

Problem is I'm trying to run GroovyArcadeLinux and my monitor goes out of range because Linux doesn't detect my display properly. Anyone know some generic code I can use to edit the xorg config file that would work for booting with a low res setting like 800x600 at startup? I know how to the program VIM.

If it helps my monitor specs are 800x600 max resolution, 30-40 Khz horizontal, 47-90 Hz vertical refresh rate. I'd like to have 16-bit video mode with 640x480 @ 60 Hz.

Even just a generic setting that will boot at low res is fine. Arcade VGA is an ATI card with modified drivers. Thanks.

You might try http://curubuntu.binghamton.edu/XORG...rg_config.html

Another thing is just to google for say "generic xorg.conf". There are many examples on the web. But the first link above may generate exactly what you want.

Is this a really small system that it has no xorg.conf provided?

This is a special linux distribution that came with a program named "GroovyArcadeLinux". It probably comes with bare bones setup options.

I noticed there is a XORG.CONF.NEW file in root that actually has a ton of setup options in it. The system seems to ignore the regular xorg.conf. Could be setup to look for different file or something. It's all so confusing.

I'm just wanting Linux to boot with a real basic setting of 640x480 @ 60Hz . It shouldn't be difficult but I know it depends on specific hardware setting.

If there is some easier generic boot setting that works, I'd go with that. Otherwise any edits I've tried so far haven't seemed to have any effect. It just picks a default resolutiin that is way too high for my monitor.

Try this one I knocked together

/etc/X11/xorg.conf
Code:

Section "Monitor"
        Identifier        "Monitor0"
        HorizSync      30-40
        VertRefresh    47-90
EndSection

Section "Device"
        Identifier        "Card0"
        Driver        "vesa"
EndSection

Section "Screen"
        Identifier        "Screen0"
        Monitor                "Monitor0"
        Device                "Card0"
        DefaultDepth        16
        SubSection      "Display"
                Depth          16
                Modes          "640x480_60"
        EndSubSection
EndSection

Do you know what the graphics adapter is? There may be something more suitable than the vesa driver, but it's a starting point anyway.

//edit: I see you say it's some kind of ATI graphics, you could try the "ati" driver which is wrapper which should select the best driver automatically, but see if it works and gives the correct resolution and refresh rate with the vesa driver first.

Thank You for trying to help Caravel. Your setting actually did do something. With the "vesa" command, when I rebooted it booted into Linux but there was no desktop display. But if I replaced vesa with "radeon" than it would display but it was still the default resolution that I don't want.

I think my video card drivers take override the vesa ones.

Sounds like the X system died trying to determine a driver for "vesa".
How 'bout trying "svga" or even "vga" or "none" or "" or even comment out that line (with a #)?

my xorg.conf settings

Thanks for the reply. I was able to create an xorg.conf file that shows my setup that may make things easier. Notice that "vesa" is assigned to "card2" in my settings. As Card0 is assigned 2 radeon.

Well I was able to figure out that the problem is not XORG but the fact that XORG is not running in the Arch Linux shell opening menu. For example if I do the command "sudo xrandr" it displays the message "can't open display". Xorg only runs when I execute a program and I can't use the command line when a program is running.

I've heard from others that Xorg should always be running?

In that case, just issue the "startx" command or call xinit directly like the way startx does it.
