I can only enter my password with the keyboard and this is what I see after I login

image of black screen with dock with grey icons

If I try to switch to a terminal with CtrlAlt+F1 I get this
image of completely black screen following Alt+F1

I don't have a clue how to fix this, or if it's even possible to fix this without access to a terminal.

The recovery console does not work either. It opens, but keyboard input doesn't seem to be working for it either.

Anybody had this happened?

Update (next day) Keyboard input lets me do Alt+F2 and invoke a terminal, but I can't change focus to the terminal window that opens. Any tip on how to switch focus (Alt+Tab wont work) to the terminal window.

Maybe looking at this you might have a clue what's going on, maybe there's no window manager loading?

Will final version of 12.04 use the power management changes found in kernel 3.3

I have seen in some version of Ubuntu that instead of making a huge change to update to the latest kernel, they take some of the good stuff out of it, for the sake of stability and put it on a previous version. In this case, kernel 3.3 has seen some very good power management enhancements that are… >>> More
