With a newly created account, I can get both monitors working, but it
is delicate and if you remove the external monitor or try to change
the display settings, then you frequently end up with black screen
(sometimes with movable X cursor).

Even if I save as default the setup with 2 screens working, if I log
in as the existing user, then I get blank screens.

What files in an account could affect this?
