You wouldn't by any chance have a dual display set-up or be using a non VGA connection are you. Even if your are not check your bios and see if dual display is enabled (Advanced Chipset in my bios).

I found if it is enabled and set to primary video AUTO or PCI-E and you are using a (in my case) HDMI connection the install will fail. Fails right after plymouth and just flashes a blinking _ in the upper left. Eventually displays Samsungs default NO Connection Msg.

My Setup is:
1 TV Plugged in threw HDMI
1 CRT monitor plugged in threw onboard VGA

BIOS / Advanced Chipset

1.)

Dual Display - Enabled // Primary Video - Auto ---> Will NOT work (displays on flatscreen)
Dual Display - Enabled // Primary Video - PCI-E ---> Will NOT work
Dual Display - Enabled // Primary Video - VGA ---> Works Everytime (if you also have a old CRT monitor connected)

2.)

Dual Display - Disabled // Primary Video - Auto ---> WORKS (displays on flatscreen)
Dual Display - Disabled // Primary Video - PCI-E ---> WORKS
Dual Display - Disabled // Primary Video - VGA ---> WORKS

* I recall one of the above 3 getting past install but then failing after restart with same black screen. I think it was auto. Unfortunately I forgot to document that one. But I have documented that PCI-E did work, so its not clear to me why auto would fail and PCI-E would work when they both were using the PCI-E connection. This might have just been a mishap but after trying to install so much once it got installed I did not want to try to recreate problem. Can someone verify?

3. (HDMI Connection and a VGA to DVI Adapter Connection)

Dual Display - Enabled // Primary Video - Auto ---> WORKS (displays on flatscreen)
Dual Display - Enabled // Primary Video - PCI-E ---> WORKS
Dual Display - Enabled // Primary Video - VGA ---> WORKS

So to me it appears this driver does not work properly with the BIOS having Dual Display Enabled.
