Re: Configuration for multiple monitors

[Harold L Hunt II <huntharo@msu.edu>]

Øyvind,

Give a man a fish, he eats for one day.  Teach a man to fish...

Source is viewable here:

http://pdx.freedesktop.org/cgi-bin/viewcvs.cgi/xc/programs/Xserver/hw/xwin/?cvsroot=xorg&only_with_tag=CYGWIN


Do the following:

1) Look at winprocarg.c/winInitializeDefaultScreens

2) Change the line:
	g_ScreenInfo[i].fMultipleMonitors = FALSE;
    to:
	g_ScreenInfo[i].fMultipleMonitors = TRUE;

3) Look at winprocarg.c/ddxProcessArgument

4) Find the section that starts with:
   /*
    * Look for the '-multiplemonitors' argument
    */

5) Add a similar section for -nomultimonitors and -nomultiplemonitors 
that sets the flag to FALSE instead of to TRUE.

6) Pull the CVS tree following the instructions here:
	http://xfree86.cygwin.com/devel/server/

7) Make your changes as above.

8) Run 'cvs -z3 diff -up > multi-monitor.diff' in hw/xwin and send in 
the patch.

9) I will compile it for you and post it in the next release.  If you 
want to compile it yourself, check the Contributor's Guide (mind you, it 
references the XFree86.org CVS tree, which has been replaced with 
freedesktop.org for us):
