Binary package hint: plymouth
When I boot the Lucid Beta 2 (or the April 17 daily) Live CD, the Plymouth text theme appears, is sized to fit the screen for second, but then the screen flashes and the splash is confined to a small box in the upper left corner of the screen. It stays like this until the "Setting sensor limits" message appears, the screen flashes once, and then the 'Plymouth box' expands a bit to the right (as if it at least realized I have a widescreen monitor at that point), but still doesn't fit the screen. From there it displays the Ubuntu desktop as expected. Curiously enough, when I shut down it displays the normal Plymouth theme as expected, and it fits my screen fine.
If it's of any importance, I previously had a problem on the same laptop where Plymouth displayed everything normally, but hung and wouldn't let me boot in Beta 1 & Alpha 3: https://bugs.launchpad.net/ubuntu/+source/plymouth/+bug/532984
