The output is displayed if I blacklist the nouveau driver (boot with rdblacklist=nouveau).

Comment 1 Jiri Koten 2012-04-17 10:27:52 EDT
The similar problem happens on Laptops with switch-able graphics, e.g. NVidia Optimus. On testing machine Thinkpad T520 (42435GG), there is option in BIOS where you can switch between discrete and integrated graphics or use both (Optimus). 

When I use the Optimus mode I don't see a graphical boot on the display. I see pre-boot msg and then X session. I'm able to switch to detailed, text mode.
When I boot with rdblacklist=nouveau, the graphical boot is displayed.
