I installed displayLink, following in detail, the instructions of this page

But, doesn't work. Appanrently in my pc, all it's ok.

  • Displaylink device: Lenovo Enhanced USB Port Replicator usb 2.0.
  • Laptop: Lenovo t430
  • OS: Ubuntu 16.04.1 LTS

I use the following commands in order to active the third monitor:

# xrandr --newmode "1024x768_60.00"   63.50  1024 1072 1176 1328  768 771 775 798 -hsync +vsync
# xrandr --addmode DVI-I-1 "1024x768_60.00

But, when I put the second command, all screen freeze and the cursor becomes very very slow, then, I restart my pc.

Also used this script unsuccessfully.

Also I put the output of some important commands:

xrandr --listproviders

# xrandr --listproviders

Provider 0: id: 0x4c cap: 0x9, Source Output, Sink Offload crtcs: 4 outputs: 9 associated providers: 1 name:Intel
