Adding screen resolutions to Linux boot CD

[philips217]

Hi guys,

I am currently customizing my own version of Morphix and everything is going smooth except I am having trouble pre-defining screen resolutions in the boot CD.
The only resolutions available on the boot CD are: 1024x768, 800x600, 640x480.
I know the monitors and video cards can handle more on the computers I am testing it on but I can’t seem to add anymore resolutions.

The way I am creating this boot CD is: mounting boot CD iso file, decompressing the files, adding and modifying the files, compressing the files, making bootable iso, burning the CD.

In the /erc/X11 directory in the CD (before I compress the files) I have:

X, Xloadimage, Xsession, Xsession.options, app-defaults, flubox, rgb.txt, sysconfig, xkb, xsm, XF86Config-4, Xresources, Xsession.d, Xwrapper.config, cursors, fonts, rstart, xinit, xserver, xwhois

I tried to manually edit XF86Config-4, and add this line:

Section “Screen”
…
	Susbestion “Display”
		Depth	1
		Modes		“1600x1200” “1024x768” “800x600” “640x480”
	EndSubSection
	Susbestion “Display”
		Depth	4
		Modes		“1600x1200” “1024x768” “800x600” “640x480”
	EndSubSection
	Susbestion “Display”
		Depth	8
		Modes		“1600x1200” “1024x768” “800x600” “640x480”
	EndSubSection

	Susbestion “Display”
		Depth	15
		Modes		“1600x1200” “1024x768” “800x600” “640x480”
	EndSubSection

	Susbestion “Display”
		Depth	16
		Modes		“1600x1200” “1024x768” “800x600” “640x480”
	EndSubSection

	Susbestion “Display”
		Depth	24
		Modes		“1600x1200” “1024x768” “800x600” “640x480”
	EndSubSection

I tried that because it only had 1024x768 and below in there before but it did not make any difference. I am thinking this file gets made at boot time or something but there must be a way to add higher resolutions to the boot CD if 1024x768 is in there in the first place.

If someone could help me here it would be greatly appreciated.

Thanks,
Philips
