    How can I modify my xorg.conf to adjust to a bigger monitor?



    Hello all,

    I recently upgraded from a 17 inch flat panel monitor to a 24 inch. Unfortunately, my xorg.conf file is set to use the resolution on my old monitor (1280x1024) instead of the new one (1920x1200). How can I reconfigure X to compensate for this change in my system? Below is the section of my xorg.conf that I thought would have to be edited. I can pretty much tell that I have to add the new resolution as a "Mode" but I didn't want to try anything out without being sure of what I was doing for fear of being graphically blocked out of my system. I would appreciate your help. Thanks.

    Code:
    Section "Monitor"
	Identifier	"SDM-HS73"
	Option		"DPMS"
EndSection

Section "Screen"
	Identifier	"Default Screen"
	Device		"ATI Technologies, Inc. RV280 [Radeon 9200]"
	Monitor		"SDM-HS73"
	DefaultDepth	24
	SubSection "Display"
		Depth		1
		Modes		"1280x1024" "1024x768" "800x600" "720x400" "640x480"
	EndSubSection
	SubSection "Display"
		Depth		4
		Modes		"1280x1024" "1024x768" "800x600" "720x400" "640x480"
	EndSubSection
	SubSection "Display"
		Depth		8
		Modes		"1280x1024" "1024x768" "800x600" "720x400" "640x480"
	EndSubSection
	SubSection "Display"
		Depth		15
		Modes		"1280x1024" "1024x768" "800x600" "720x400" "640x480"
	EndSubSection
	SubSection "Display"
		Depth		16
		Modes		"1280x1024" "1024x768" "800x600" "720x400" "640x480"
	EndSubSection
	SubSection "Display"
		Depth		24
		Modes		"1280x1024" "1024x768" "800x600" "720x400" "640x480"
	EndSubSection
EndSection

    Given the fact that the "default depth" is set to 24, you only need to change the mode in the related section, to which you can add your monitor's resolution :
    Code:
    [...]
SubSection "Display"
		Depth		24
		Modes		"1920x1200" "1280x1024" "1024x768" "800x600" "720x400" "640x480"
	EndSubSection
[...]
    There is really nothing to it. Just make sure you do a backup of the original file before modifying it.

    If you prefer not to modify the file by hand, you can use the X configuration tool that comes with your distro (which distro is it ?).
