DisplayLink and Ubuntu 17.04 (intel)

I had a problem with DisplayLink drivers on my Dell Precision 5510 (XPS 15) after upgrading to Ubuntu 17.04.

The monitors connected to the DisplayLink device was enabled and identified, but the screens stayed all black.

Of course, there’s a solution. I found this evdi issue, containing a solution.

Create the file (and directory) /etc/X11/xorg.conf.d/20-intel.conf, with the content:

Section "Device"
  Identifier "Intel Graphics"
  Driver "Intel"
  Option "AccelMethod" "sna"
  Option "TearFree" "true"
  Option "TripleBuffer" "true"
  Option "MigrationHeuristic" "greedy"
  Option "Tiling" "true"
  Option "Pageflip" "true"
  Option "ExaNoComposite" "false"
  Option "Tiling" "true"
  Option "Pageflip" "true"
EndSection
