computer freezes/hangs when I plug in external monitor

[pepperminty]

When I plug in the external LCD monitor to my laptop's VGA port, the computer freezes after getting past the login screen.
Before or while in the login screen, there is no freeze. (We can therefore rule out any problems with hardware, with either the laptop and its VGA port or the monitor.)

When I login without any monitor attached and then later plug in the monitor, the computer freezes. My desktop background of the mountains looks like it is chopped into four squares.

While powered off, I unplugged that external monitor (a Viewsonic). I then plugged in another monitor (Acer). When I boot up into Mint 13, I go to "Monitors" (monitor preferences) and see that that the monitor are mirror images. When I turn off "mirroring" and adjust the monitors to have a setup similar to the attached screenshot, the computer again hangs. Note how my laptop monitor and the external monitor are not on the same "floor". Could this be what's causing problems?

Same issue.

Note that I had the same conditions i.e. no problem when 'mirror screens' was checked, but as soon as it tried to handle the different screen sizes, CPU went to 100% and the system froze.

I worked around this issue by using 'Gnome Classic' instead of cinnamon.

Amir, I am the OP. What happens when you use MATE.
