setting video resolutions that are not shown

[John Bird]

Hi can somebody provide me with advice on how to set video resolutions that are not offered in setting. Kubuntu seems to have detected my video card (ATI All-in-wonder 9600 but only offers me a max resolution of 1024 x 768, normaly I use 1280 x 1024

Start a konsole: K>System (NOT System Settings or System Menu)>konsole. Then type

sudo dpkg-reconfigure xserver-xorg

Before you do this though, write down the range of values for the Horizontal Sync frequency and the Vertical Refresh rate of your monitor. You can find these in the owners manual or on the manufacturer's web site if you know the model number. Then just set the preferred screen size when asked.

Alternative:

First backup /etc/X11/xorg.conf
sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf_backup

Then add resolution 1280 x 1024 to xorg.conf
kdesu kate /etc/X11/xorg.conf

You have something like this (i have 9600XT):

Section "Screen"
	Identifier	"Default Screen"
	Device		"ATI Technologies, Inc. Radeon 9600 XT (RV350 AR)"
	Monitor		"Generic Monitor"
	DefaultDepth	24
	SubSection "Display"
		Depth		1
		Modes		"1024x768" "800x600" "640x480"
	EndSubSection
	SubSection "Display"
		Depth		4
		Modes		"1024x768" "800x600" "640x480"
	EndSubSection
	SubSection "Display"
		Depth		8
		Modes		"1024x768" "800x600" "640x480"
	EndSubSection
	SubSection "Display"
		Depth		15
		Modes		"1024x768" "800x600" "640x480"
	EndSubSection
	SubSection "Display"
		Depth		16
		Modes		"1024x768" "800x600" "640x480"
	EndSubSection
	SubSection "Display"
		Depth		24
		Modes		"1024x768" "800x600" "640x480"
	EndSubSection
EndSection

Just add 1280 x 1024:

Section "Screen"
	Identifier	"Default Screen"
	Device		"ATI Technologies, Inc. Radeon 9600 XT (RV350 AR)"
	Monitor		"Generic Monitor"
	DefaultDepth	24
	SubSection "Display"
		Depth		1
		Modes		"1280x1024" "1024x768" "800x600" "640x480"
	EndSubSection
	SubSection "Display"
		Depth		4
		Modes		"1280x1024" "1024x768" "800x600" "640x480"

You know ...
