I believe this may well be a duplicate of #558378 (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/558378), i.e. related to a bug in the ATI module. I experienced the exact same issue on a Samsung R20 (same gfx card). The workaround in the report of #558378, i.e. providing radeon.modeset=0 as a startup parameter (via "F7" in the Ubuntu startup menu when booting from CD) worked well for me.
