How do you change the resolution of the login screen in Ubuntu 9.10 (Karmic)?
Edit: keep in mind that I need to change the resolution of the login screen, as explained below.

What you want to do is change the GDM LOGIN Screen resolution?
Read this and please accept the correct answer.
Justin was kind of correct except the fact that GDM uses the modeline from your xorg.conf. The priority runs from left to right, so if you add "1280x960" as the first entry and remove any items you don't want (who needs half of them anyway, 768x600 or whatever it was, madness.) you should be fine for GDM.
SubSection "Display" Depth 24 Modes "1280x960" "1024x768" EndSubSection
EndSectionLet me know if you need further explanation.
0I believe you need to configure your xorg.conf to include the proper modes.
edit /etc/X11/xorg.conf
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
EndSectionWhere the first Mode is the default resolution.
If you have an ATI card you may try this as well.
sudo aticonfig --resolution=0,1280x1024,1024x768,800x600Where 0 is the first screen, and the resolutions are in order of preferred first.
Try adding this as a subsection to the 'Screen' section in your xorg.conf
SubSection "Display" Virtual 1280 800
EndSubSectionIf you don't have a special X11 configuration but you do happen to have a file /etc/X11/xorg.conf, you might want to try moving it aside and see what happens. Usually X11 should configure itself properly these days and in my experience having stuff in /etc/X11/xorg.conf often causes problems.
To try without the file:
sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.backupand restart.
If it doesn't help move it back:
sudo mv /etc/X11/xorg.conf.backup /etc/X11/xorg.confand restart once more.
