Comment 9 for bug 1053269

i'll gather both dmesg and paste it here asap ;)

I'm saying that the screen goes black during the boot sequence (just after grub) but then lights itself up again at lightdm (so when X goess up)

In that black period I don't see the usual plymouth splashscreen neither i'm able to switch to any virtualterminal to see what is happening. The framebuffer is not opened or refreshed after grub.
