ubuntu 7.04 to 8.04 all had in the menu "Screens & Graphics GUI for setting up. Or via terminal displayconfig-gtk. Useful if you want to use two monitors or have an electronic whiteboard.
Just been trying out 8.10 wondering how much has been changed from 8.04 and couldn't find displayconfig-gtk. I thought they might have put it in 'configuration editor' but haven't.
Has it been replaced with another app - doesn't seem likely to have left it out expecting you to change xorg instead?
thanks james
