I did a package manager update yesterday and it turns out that my dual monitor setup has stopped working. I have poor vision so I really need to connect to a much bigger screen, but since yesterday, when I connect the screen to my laptop, the screen does not automatically reset itself to the laptop display. Even after lots of trial and error with the display settings, I am getting different dispalys on the laptop and external screen and right now only the big screen is active while the laptop has blanked out.

Please can someone help me setup my dual screens for 11.10 properly.
