Please confirm I know what I need to add to my XF86Config

I'm trying to set up my monitor so it's at the native resolution 1680*1050. I believe I know what I need to add to my XF86Config, I just need to find out the specific values. If you could tell me that I know what I need to add and understand it.

The first section is Monitor. I think I've got this down. I found someone else's config with a similar monitor to mine and they used the line:

Code:

Option    "dpms"

Could you explain what this means?

Next is Modes. Here is what I believe I need to add:

Code:

Section "Modes"
        Identifier "Mode[0]"

        Modeline "1680x1050" 256.20 1680 1808 1992 2304 1050 1051 1054 1112
EndSection

Don't worry, those aren't the specific numbers I'll use, I've got to find those out.

Finally the subsection Display under Screens:

Code:

Subsection "Display"
        Depth       24
        Modes       "1680x1050"
    EndSubsection

The same config I mentioned earlier also had the line:

Code:

        ViewPort    0 0

Could you explain this?

Thanks in advance, I think that's about all for now...

Edit: Forgot to ask if it's possible I could damage or break my monitor by using the wrong modelines. I'm on a laptop so it'd be even more devastating it it happened. Are there any kind of "safe values" I could use that would drive it to 1680*1050 if I couldn't find out the exact ones.

The subsection will try to get the resolution you want. You have another option you didn't mention

DefaultDepth 24

Values 8, 16, 24, 32

In your case 24. If it doesn't work for you try 16 and put the subsection in 16 as well.

defines that your monitor can suspend (advanced power management)

you need at least one.. but i have one more for 640 480 to show dvds... i have a slow computer and 640 480 goes faster...

i like to stick to one depth. .24 is good... you don't need any more really..
remember this is als where you add other modelines you allow, like:
Modes "1680x1050" "640x480"

you can make your virutal screen larger than your actual screen.. it's nice to try.. set it to 2000 2000 and see what happens... you'll understand when it runs...

well... old screens you could really fsck up.. newer screens all have a built in safety system... they don't allow wrong values.. and flascreens don't really work with cathodes that you can burn... you'll just get a blank screen... if you see really weird things quickly close the laptop and take the battery out and ... hahaha.. no don't worry man

I guess I should add some more for games that run at certain resolutions...

Thanks for explaining it all, I'll try it after I get my ATI driver working as I don't think it'd run at 1680*1050 with the VESA Framebuffer.
