Not only happening on ARM:
Same problem with ubuntu-12.10-desktop-i386 on an Acer Aspire One 722 with AMD C-60 APU.
After starting the PC you see the - BIOS-Logo, - blinking cursor, - Screen goes on, - Screen goes off.
The only workaround is to switch with CRTL+ALT+F2, then CTRL+ALT+F7.
After that everythings normal and i enter my password for the hdd encryption.
