Public bug reported: Roughly 25% of the times I boot my computer, I get a completely blank screen instead of the dm-crypt passphrase prompt. Typing in the passphrase works buts results in a blank screen when logging into ubuntu (or kubuntu in my case). This could be resolved by pulling the monitor plug and plugging it back in again (or probably by switching screens with CTRL-ALT-F6 /F7 as OP noted).
