Public bug reported:
After upgrade to kernel package linux-image -3.8.0-13-generic the native
1600 x 900 display in my laptop is not correctly detected, and a 1028 x
768 screen is displayed. This appears during the boot process, before
login, and persists after login. System Properties | Display does not
show any display size option larger than 1028 x 768 (4:3). No error
messages in Xorg.0.log.
