Question Resolution for WideScreens


Hi. I am running linuxmint . Trying to configure my start-up resolutions using the Startup Manager. But they only offer 4:3 resolutions. (My screen is a widescreen, 1600 by 900). So I could check the 1600 x 1200 option but that is not the correct resolution. Any thoughts would be appreciated.

Run "xrandr" to list the resolutions.

You could use
gtf 1600 900 59.9 -x

to manually create a modeline to use in your /etc/X11/xorg.conf file. If this is an LCD monitor, I would just use the native resolution of the monitor. You could add the modeline to the "Monitor" section, and then add the modeline title to the "Display" subsections.
Code:
Section "Screen"
	Identifier	"Default Screen"
	Device		"Generic Video Card"
	Monitor		"Generic Monitor"
	DefaultDepth	24
	SubSection "Display"
		Depth		1
		Modes		"1600x900@59" "1440x900" "1152x900" "1024x768" "800x600" "640x480"
	EndSubSection
	SubSection "Display"
		Depth		4
		Modes		"1600x900@59" "1440x900" "1152x900" "1024x768" "800x600" "640x480"
	EndSubSection
...
Be sure to backup your old xorg.conf file before making changes. E.G. cp /etc/X11/xorg.conf /etc/X11/xorg.conf.bu

Then you can copy over the new xorg.conf with the old one if the Xorg server doesn't start.

What's the output when you run the "xrandr" command?
