how can we add modelines from xorg.conf on ReactOS?

[nitrofurano1]

On GNU/Linux i use custom display resolutions a lot, added from xorg.conf modelines.
How can we add these resolution on ReactOS as well? Is that a simple text file to edit (like /etc/X11/xorg.conf on GNU/Linux), or do we need a special tweak tool for that?

(these modelines can be obtained from http://arachnoid.com/modelines/ or http://xtiming.sourceforge.net/cgi-bin/xtiming.pl )

thanks in advance!

ReactOS is a Windows-like OS, custom mode can be added via registry setting.

how can i do it using command lines only?

As far as I'm aware, that's not (easily) possible. The best-case scenario is to use one of the following tools:

• QRes
• MultiRes
• Display Changer II

I believe the first two support command line use as well.

The only other option is to use something like:

Code: Select all

REG ADD HKEY_CURRENT_CONFIG\System\CurrentControlSet\Control\VIDEO\{GUID}\0000\Mon12345678 /v DefaultSettings.XResolution /t REG_DWORD /d 400

To change your X resolution, but I'm not convinced that you could get this to work (at all).

Also it appears that the modeline features allows you to customize the display timings, while I'm not aware of a similar feature on Windows.

You should have a look at the sample monitor inf file from the Windows DDK and related documentation to get a clue how to archive what you want.

Also it appears that the modeline features allows you to customize the display timings, while I'm not aware of a similar feature on Windows.

Well, if you add a custom mode to your monitor, you have to tell the system which timings it uses.
