If you have other steamvr plugins intalled, e.g. the osvr plugin in /usr/lib/openvr/osvr/, remove it temporarily to avoid with annoying behavior like slow osvr startup:
~/.local/share/Steam/SteamApps/common/SteamVR/bin/linux64/vrpathreg removedriver /usr/lib/openvr/osvr

If you do want to use it later, enable it again:
~/.local/share/Steam/SteamApps/common/SteamVR/bin/linux64/vrpathreg adddriver /usr/lib/openvr/osvr

Set up ~/.local/share/Steam/config/steamvr.vrsettings like this:

{
   "driver_lighthouse" : {
