Debian screen resolution problem


Recommended Posts

I installed debian on a spare PC today, and the screen resolution is stuck at 640 X 480. I have checked that the correct drivers are installed ( fglrx for my ati raedon) and my xorg.conf file has the native resolution listed, but I still can't choose it using the Gnome control center screen resolution app. Here is a shot of my xorg.conf file -

Xpress 200G Series]"
	Monitor		"VP171b"
	DefaultDepth	24
	SubSection "Display"
		Depth		1
		Modes		"1280x1024" "1152x864" "1024x768" "832x624" "800x600" "720x400" "640x480"
	EndSubSection
	SubSection "Display"

	EndSubSection
	SubSection "Display"

	EndSubSection
	SubSection "Display"
		Depth		15
		Modes		"1280x1024" "1152x864" "1024x768" "832x624" "800x600" "720x400" "640x480"
	EndSubSection
	SubSection "Display"
		Depth		16
		Modes		"1280x1024" "1152x864" "1024x768" "832x624" "800x600" "720x400" "640x480"
	EndSubSection
	SubSection "Display"
		Depth		24
		Modes		"1280x1024" "1152x864" "1024x768" "832x624" "800x600" "720x400" "640x480"
	EndSubSection
EndSection

I'm trying to run it at 1280 X 1024, but no luck. Any ideas?

Try this then:

Monitor		"VP171b"
	 DefaultDepth	24
	 SubSection "Display"
		 Depth		16
		 Modes		"1280x1024"
	 EndSubSection
	 SubSection "Display"
		 Depth		24
		 Modes		"1280x1024"
	 EndSubSection
 EndSection

I tried to edit the file, still no luck. Here is the full xorg.conf file, hope this helps. Thanks again.

Use the radeon driver, not fglrx, both 9100IGP and x200 have never been supported proprely, their is solution to your problem, but fglrx does not worth it for this card. You can also remove the xorg.conf file if you use a recent version of xorg (7.3 or 7.4) it will autoconfigure itself on the fly and xrand applet will work better.

Isn't "ati" the generic Open Source driver? If you have installed and want to use the "fglrx" driver, I think you need to set the card to "fglrx".

* DISCLAIMER: I am an nVidia type of person, and have never set up an ATI card in Linux.

You might also want to add your monitor's horizontal and vertical refresh rate....

Mine is set as follows:

Section "Monitor"
	Identifier	"VE175-2"
	Option		"DPMS"
	HorizSync	30-82
	VertRefresh	50-75
EndSection

This section is right above the "Screen" section.... I run Debian also, and this did the trick for me on several occasions. Just Google your monitor's specs to get them.....;)

I had this problem and tried editing xorg.conf and drivers when all I needed to do was unhide an option in the gmenu. Have a look through the menu editor for something about screen settings that is hidden by default. I think editing xorg.conf was supposed to enable new resolutions in the Gnome control center screen resolution app but only a few low resolutions showed up for me.

Note: I am a linux noob.
