Support Ubuntu 17.04
Ubuntu 17.04 is not supported. I'm using a Dell D6000 docking station.
Network and USBs work, but headphones, monitors don't.
Also the current release cannot be installed without disabling Secure Boot.
Ubuntu 17.04 is now end of life, (since Jan 2018) so we do not plan any further changes for this version of Ubuntu.
But ubuntu 18.04 LTS not, and it's kernel 4.18 gives frequents screen freeze (blank screen). I hope you solves quickly...
Officialy Ubuntu 17.04 is supported with the v1.4 driver, but that's not true. please find those performance regression reports:
