Yeah, thanks, I used to edit those X config files years ago on RedHat,
so this isn't *that* new to me. I have something like this:

Section "InputDevice"
	Identifier	"Generic Keyboard"
	Driver		"kbd"
	Option		"XkbRules"	"xorg"
	Option		"XkbModel"	"pc105"
	Option		"XkbLayout"	"pl"
EndSection

Section "InputDevice"
	Identifier	"Configured Mouse"
	Driver		"mouse"
EndSection

Section "Device"
	Identifier	"Configured Video Device"
	Option		"UseFBDev"		"true"
EndSection

Section "Monitor"
	Identifier	"Configured Monitor"
EndSection

Section "Monitor"
	Identifier      "SSM 550b"
	VendorName      "Samsung"
	ModelName       "SyncMaster 550b"
	VertRefresh     85
EndSection

Section "Screen"
	Identifier	"Default Screen"
	Monitor		"SSM 550b"
	DefaultDepth    16
	Subsection      "Display"
                Depth           16
                Modes           "1024x768"
        EndSubSection
EndSection

I tried "VertRefresh 85" because I know this monitor can handle 1024x768
@ 85 Hz (well, at least it used to several years ago). Unfortunately the
error I am getting now is: "vrefresh out of range" and I am only able to
run X at:

720x400x16 @ 85Hz, or
800x600x16 @ 60Hz

(nothing better).

So probably it is the card that cannot handle 1024x768 @ 85 Hz? I even
tried 8-bit color for that but with no success. :-(

On the other hand, those years ago on RedHat I used to configure those
"mode" lines manually.... I will let you know should I make it work at
1024x768 @ 85 Hz.
