Extracting the driver components

The Ubuntu driver components can be extracted for repackaging using the command: 

./displaylink-driver-0.9.68.run --noexec --keep

The following files will be extracted:

  • ./
  • displaylink-installer.sh - The installation shell script.
  • evdi-1.0.68-src.tar.gz - The open source code, from GitHub
  • LICENSE
  • ella-dock-release.spkg - The firmware image for DL-3xxx and DL-5xxx devices. This will be programmed into the DisplayLink IC, if the current firmware version in the device does not match this version.
  • firefly-monitor-release.spkg - The firmeware image for DL-4xxx devices. This will be programmed into the DisplayLink IC, if the current firmware version in the device does not match this version.
  • ./x86 and ./x64
  • DisplayLinkManager - The user mode binary driver for DisplayLink devices
  • libevdi.so - The pre-built library taken from the open source evdi project code
  • libusb-1.0.so.0.1.0 - The standard, unmodified library to access our DisplayLink USB devices. The source code for this is also available.
