Change login screen resolution?

[kcy29581]

Hi all,

When Ubuntu boots up and loads Xorg, the first screen you see is the login screen.

The resolution has been set higher than I prefer. To make things clear, my monitor has been 100% detected, and Ubuntu has set my default resolution to the highest possible for my monitor, 1280x1024. I would rather have it at 1024x768.

I have set the resolution to 1024x768 in the desktop, using System -> Preferences -> Screen Resolution. All is fine there! But this makes no difference to the login screen resolution.

I have found a way to deal with this: If I remove all references to 1280x1024 in /etc/X11/xorg.conf (in the Screen section -> Modes) then it defaults to the next highest resolution, 1024x768. But when I do this I feel like I'm crippling my monitors abilities, say if a game ever needed the highest resolution. So I'm looking for a cleaner (gui?) way of dealing with this.

Any help or advice would be appreciated!

In /etc/X11/xorg.conf, the first entry in the "modes" lines of the various Screen->Display subsections determines the default resolution for X.

So, for instance, if this is the Screen section in my xorg.conf file, the default resolution will be 1024x768:

Section "Screen"
	Identifier	"Default Screen"
	Device		"NVIDIA Corporation NV43 [GeForce 6600 GT]"
	Monitor		"17P3"
	DefaultDepth	24

	[...]

	SubSection "Display"
		Depth		24
		Modes		"1024x768" "1280x960" "640x480" "800x600"
	EndSubSection
EndSection

The higher 1280x960 resolution is still available.

Hope that helps

it didn't work for me. i put "1280x1024" first on all the Display sub sections i have in my xorg.conf file. I even tried to completely remove the "1600x1200" resolutions within the sub sections but the resolution during the startup screen and the login screen are still to big for my monitor. Any ideas?

I always do that with the simple way, in Gnome's resolution settings choose the resolution you want and then mark the 'make default for this computer'-box.

backup before you edit it with

cp /etc/X11/xorg.conf /home/<Your Username>/Desktop

edit with

gksudo gedit /etc/X11/xorg.conf

note in linux all is case sensitive

Once open scroll down to the bottom but make sure your screen supports thie resolution.
If you do something wrong, np you have a backup than.

LantagoniE, you might be editing the wrong section of xorg.conf, as I was. Found a solution here:
