My multiple monitor configuration has got into a bad state. After unplugging my computer for a short time, I am unable to return to my precious configuration.
In Vista (and I think windows 7) I could have followed these instructions to delete the registry subkey
HKEY_CURRENT_USER\Software\Microsoft\MobilePC\TMM, however the MobilePC key does not exist in my registry.
How do I clear the multiple monitor configuration?
