[Bug 1065902] Re: black/blue screen before installer, tty switch fixes it

 

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.

  During a test installation, after the purple Ubuntu splash screen, the user is greeted with a black or blue screen instead of the installer.
  Switching tty and back (ctrl+alt+f1 and alt+f7) fixes it.
