xorg - Resolution stuck at 1024x768

In an attempt to fix some minor issues with the splash screen, I ran this script: http://www.webupd8.org/2010/10/script-to-fix-ubuntu-plymouth-for.html

Big mistake. My resolution is now stuck at 1024x768 (the screen is 1280x900). I can't change it through the Monitors settings, and either there's lots of old guides out there or my Xorg config doesn't exist. I tried running the cleanup version of the "fix script" but nothing changed. Oh and the graphics settings are also at minimum all of a sudden.

I also tried all sorts of dpkg --reconfigures, no luck there either.

alexander@natty:~$ xrandr 

xrandr: Failed to get size of gamma for output default

What this script does:

1. In /etc/default/grub

   
   
   
   
   

   1. replace

      
      
      

      GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

      
      
      

      with

      
      
      

      GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset video=uvesafb:mode_option='$resolution',mtrr=3,scroll=ywrap"

   
   
   
   2. set GRUB_GFXMODE=$resolution
   
   


2. In /etc/initramfs-tools/modules
   
   
   
   1. add uvesafb mode_option=$resolution mtrr=3 scroll=ywrap
   
   


3. In /etc/initramfs-tools/conf.d/splash
   
   
   
   1. add FRAMEBUFFER=y
   
   

Reverse whatever it actually did do, and do this:

 sudo update-grub2
 sudo update-initramfs -u
