Can you

Code:

Alt+F2

then type 'r' and hit enter? You can't see it but this will refresh GDM for you (That's if you're using that desktop manager)
If that does nothing can you

Code:

Ctrl+F2

into a console? Then you might be able reload your display manager (although this will kill your current session) so I think that you can reload the DisplayLink service itself first with something like

Code:

sudo service displaylink-driver restart

.

I've found that sometimes the display manager would have issues with not displaying onto my internal screen (it would still act as if the display was disabled - as I used to have my laptop lid closed whilst using the other monitors.) There may be something in the

Code:

/var/log/syslog

.
