Bug Description
Started the Ubuntu 12.04 demo iso from USB on my Sony Vaio X
1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu
Description: Ubuntu precise (development branch)
Release: 12.04
Beta 2
2) The version of the package you are using, via 'apt-cache policy pkgname' or by checking in Software Center
?
3) What you expected to happen
The screen should be set to 1366x768 (wide).
4) What happened instead
Screen is either (initially) chopped off horizontally on the try/install page. When clicking to try, ubuntu is started with the resolution set to 1024x768 leaving the right/part of the screen impossible to reach and filled with garbage/static/part of VAIO-logo. Also unable to change the resolution in settings. Also the top part of screen flicker.
See attached photo.

All as described happened the first time i ran the "Try Ubuntu". I shut everything down and did everything exactly the same a second time to confirm and write this bug report.
Afterwards I have tried 2 more times (also exactly the same) and the screen resolution worked both times (nolonger an issue).
BUT - The Try/Install page is always split in the middle and the far top of the screen keeps flickering as described (to be exact, the entire screen is flickering with seemingly diagonal lines moving across light purple/orange/gray areas - difficult to describe but annoying to such degree that is affecting usability - almost as much as Unity :-).
