I would prefer the restore operation to abort with a message "saved info
is for a different display configuration".

The next step would be to keep several saved configurations, and present
a menu of which one to restore (one for laptop only, one for laptop plus
home monitor, one for work monitor).

However, it is not easy to detect the monitor setup. On MS windows,
laptop + monitor is just one big display, and you can have windows at
negative positions (which breaks all kinds of assumptions!).
