For future refence, this is an optimus system and you are using the
intel GPU even though both GPU's are on at the same time. Installing the
nvidia binary drivers breaks 3D for the Intel leading to the 2D desktop
after. The images shipped with these systems for lenovo worked around
this by a kernel command line option (acpi_osi="!Windows 2009") that
pretended to be windows XP so the bios autodetection wouldn't try to use
optimus and instead default to just the nvidia GPU. They GPU to use can
also be picked in the bios manually on lenovo.
