This has been working for 2 months before the last shutdown.

I booted from the Live CD. I could then get either DVI or Analog depending on how I set my monitor. I was using nvidia 180 drivers.

I then restarted from my hard disk. I uninstalled nvidia drivers. I then reinstalled nvidia 180 drivers from Admin>Hardware drivers. It did not work. I could not switch from Analog to DVI.

Does anybody have any ideas on how to do this?
