Comment 0 for bug 749361

I have two cases :
→ after GRUB, i I have a black screen (no plymouth, no gdm), I can just reboot with ctrl+alt+suppr
note: the mute LED becomes orange

→ I randomly press the contrast key up during the boot, plymouth doesn't appear, but i can log in
note: the mute LED doesn't light (it's the expected behavior)
