Wrong screen resolution

[OttoMann]

Hi!

It seem impossible to set the screen resolution to the right one.
LCD resolution is 1280x800 (native), but under Administration/Display it's impossible to set it over 1024x768.
The settings are Display type: LCD Panel 1280x800 and Graphic card : Intel Corporation Mobile 915GM/GMS.......

I use an Acer Travelmate2420 with an 1280X800 native resolution LCD and an Intel 910GML integrated chip.

try adding the following to your /etc/X11/xorg.conf file (backup the file first, insert inside the Screen section):

Modes "1280x800" "1024x768"

if you are not to sure where to put that line ,it is in this section

Section "Screen"
	Identifier "Screen0"
	Device     "Videocard0"
	Monitor    "Monitor0"
	DefaultDepth     24
	Option	    "UseEvents" "False"
	Option	    "RenderAccel" "True"
	Option	    "Composite" "Enable"
	Option	    "AddARGBGLXVisuals" "true"
	Option	    "metamodes" "1024x768 +0+0; 800x600 +0+0; 640x480 +0+0"
	Option	    "NVAGP" "3"
	SubSection "Display"
		Depth     24
		Modes    "1024x768" "832x624" "800x600" "720x400" "640x480" "640x400" "640x350"
	EndSubSection
EndSection

Thank you both ivancat andJohnVV.

I tried the suggested solutions but nothing changes.

This is hov that part of xorg.conf look's like:

Section "Monitor"
Identifier "Monitor0"
ModelName "LCD Panel 1280x800"
HorizSync 31.5 - 50.0
VertRefresh 56.0 - 65.0
Option "dpms"
EndSection

Section "Device"
Identifier "Videocard0"
Driver "intel"
EndSection

Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
Modes "1280x768" "1024x800"
EndSubSection
EndSection

Any suggestons?

Any suggestons?

[JohnVV]

try adding the option

Option	    "metamodes" "1280x800 +0+0;1024x768 +0+0; 800x600 +0+0; 640x480 +0+0"
--- and ----
SubSection "Display"
		Depth     24
		Modes    "1280x800" "1024x768" "832x624" "800x600" "720x400" "640x480" "640x400" "640x350"
	EndSubSection

Tried.... and failed..

The 1280x768 was an hint from my friend.

[OttoMann]

Option "metamodes" ..... also don't seem to work. Tried both versions the long one and the short one.

Is there perhaps an special way in changing xorg.conf and I'm doing it wrong?

I usually go to console, into root, use nano /etc/X11/xorg.conf, write my stuff, save (CTRL-O write to), exit nano, exit root, exit console and restart.

[ivancat]

hmm, try log in, go to System > Preferences > Hardware > Screen Resolution and check if 1280x800 is there. If it is. choose it and tick the checkbox "to use for this computer"

[OttoMann]

Did as you suggested the 1280x800 resolution is there and it is enabled, but the checkbox "to use for this computer" is not there.

[OttoMann]

When I run xrandr -d in terminal I get this:

Screen 0: minimum 320 x 200, current 1280 x 800, maximum 1280 x 1280
VGA disconnected (normal left inverted right x axis y axis)
LVDS connected 1280x800+0+0 (normal left inverted right x axis y axis) 304mm x 190mm
1280x800 60.0*+
1024x768 60.0
800x600 60.3
640x480 59.9
TV disconnected (normal left inverted right x axis y axis)

But Administration/Display still only allows 1024x768 max.
