Screen size is set to 800x600 which should be changed to 1024x768 this was caused by using the live cd MCNLive and for some reason this was changed.The strange thing is that Windows Xp isn't affected when logged in.

It goes like this during bootup

Dell Screen-800x600
Grub Boot-800x600
Grub Main Screen-800x600
Suse Loadup-800x600
Suse Main-800x600
Windows Xp Load Up(progress bar)-800x600
Windows Xp Log In
Windows Xp main theme-1024x768

Could it be one of these be the problems
