how to configure Xorg to run at 1280x1024

[Gary Kline]

	People,

	One of my larger servers has 5.3 and Xorg; I can't find the
	right configuration setting for the display; so it runs at 
	its maximum: 1600x1200.  This would be fine except that the
	apps shake with tiny wavy lines.  The driver may be pushing
	things to their limit.

	I've tried X -configure and Xorg -conf.  Somehow or other 
	I've generated an xorg.conf in /etc/X11, but no luck in
	changing the resolution.   The closest I've come to having 
	things work with xorg.conf and startx is to see a blank/grey
	screen--at 1600x1200.  I have ctwm set up in /root and 
	/home/kline.

	Modifying the Screen Section messes things up for some 
	reason.  I finally *do* have xorg working with /etc/X11/xorg.conf
	but only with the following commented:

###Section "Screen"
        ###Identifier "Screen0"
        ###Device     "Card0"
        ###Monitor    "Monitor0"
        ###DefaultDepth     8
        ###SubSection "Display"
                ###Viewport   0 0
                ###Depth     8
                ###Modes    "1280x1024" "1280x960" "1152x864" "1024x768" "800x60
0" "640x480"
        ###EndSubSection
###EndSection


	I'll append my current xorg.conf file and hope that somebody can
	tell me how to tweak it so that my max-resolution is
	1280x1024 rather than 1600x1200.

	thanks in advance,

	gary
