[ubuntu] Ubuntu now starts up with wrong display ratio

view story

http://ubuntuforums.org – Hi Recently on bootup i accidentally pressed the wrong key when the Grub menu came up and went into the "recovery mode" for my Ubuntu 12.04 LTS install. After navigating through the menus i selected the option to resume normal boot, which failed to activate some of the graphics drivers (it gave me a warning to tell me about that). Since then, every time i boot up, i get 1368x768 resolution at the login screen then ... 1024x768 in my user session. Thus every time i log in i have to go straight to the cog menu on the right > Displays > set the correct resolution again. Any help p (Hardware)
