I just received my Retina MacBook today, upgraded to Lion and now I have this problem too!
Does anyone know how to get rid of this?

I got a similar black screen after login, regularly but not always:
For me, it happens also when plugged into power.

I have repeatedly verified it's only a problem for me on battery power, and happens 100% of the time
looks like your issue is slightly different than mine

Yeah, if you reboot while away from AC power you are screwed, unless you turn off graphics switching ahead of time

One thing that worked for me to was to plug in and unplug an hdmi display. It seemed to force the cards back into the proper state.

Apple just released an update for the retina pro, to enable power nap and fix several sleep/wake issues. I applied it and retested, still have the same issue

I just had this exact same issue happen, everything was fine prior to the Mountain Lion update. This morning when I logged in, I received the black screen, power cord was plugged in.
To get away from the black screen, I disconnected the power cord and held down the power button. Once rebooted and logged in I then attached my power cord.

I had the same issue and managed to reslove it.
Shut down your machine.
Power it back on while holding the 'shift' key (left or right, doesn't matter)
You will see a greay progress bar go across the screen while you boot in to 'safe boot'
Once booted, login, and go to Energy Saver and turn on 'Automatic Graphics Switching'.
Reboot back in to normal mode, and you should be able to log back in and see again.
I did this without being plugged into AC power.
Hope it helps!

ben.lausman's suggestion worked for me. I kept my laptop plugged in the whole time though while changing the graphics switching setting and it still fixed the issue.

I get this too. All I do is close the lid, let it go to sleep and then open the lid again and unlock it. Seems to be the switch to integrated graphics that it doesnt like on mine.
PITA but easily worked around.
