  Lenovo (14" laptop ith intel core i5 2410M cpu and nvidia geforce 520M cuda 1GB --ith optimus)
  Mint (older version)
  Works perfectly
What works:

Basic laptop function... all works

What doesn't work:

Dislpay link docking station hooked to external monitor works -only if dock is powered on after the sytem has booted.
Display link toshiba dock has also issues in audio-output -detects as 7.1 sound system ouput -but does not function.
Have also a 22" VGA hooked directly to the laptop, thus offering 3 screens (including laptop screen).
USB TV stick -functions but signal detection is lower than windows OS

What was done to make it work:

Connecting the displaylink docking station AFTER boot up and leaving it ON till system shut down is the key! Infact monitors can be powered ON/OFF without issues if this is adhered too. Else a new login session is initiated!
