Hi Mark,

Something does not sound correct in your startup.

Indi, via EKOS, should be running with the indi_dsi_ccd loaded and running prior to starting PHD2 Connect.

You can try just launching indiserver with indi_dsi_ccd, no Kstars or Ekos, to get there

Open a terminal window
Then run
/usr/bin/indiserver /usr/bin/indi_dsi_ccd (given the paths you provided above).

Does this error out for you?

Then launch PHD2 and do the Connect.

Unfortunately I am about 1k miles from my astro equipment for the next few days, and I have 3 various flavors of DSI (1 mono, 1 color, 2 mono) to walk it all through.
