I used to fix the resolution of my screens (Which occur quite often, we have 5 computers having this problem at office and one at home) by setting and adding mode with xrandr in the gdm start script.

This tip was given here

But this time in 12.10 I am unable to find any file like that /etc/gdm/Init/Default. Does anyone know if there is still one startup script at the launch of LightDM graphic session ?

I found how to do it using ~/.xprofile but the draw back is the login screen does not have the new resolution nor the UBUNTU startup logo (This last is for sure not a big problem only it would make better feeling for windows users coming to see our beautiful Linux machines...) It also need to be done for all sessions. –  CedSha Shaced Jan 17 '13 at 17:36
