tested with kernel night build 3.11-rc7, still have the same problem with internal LCD. ( no issue at all with any kernel for external connected LCD via vga port)

machine: dell inspiron 1501, onboard video card ATI Xpress 200m (RS460).

workaround:

follow the lightdm_delay script provided by Id2ndR (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1029790/comments/60)
