[SOLVED] Black screen in VNC at startup

[EdwinM]

black. I can also F8 to minimize vnc, via the pop-up menu, and that gives me a normal desktop. So VNC seems to be running but not mirroring a desktop or something similar?
Did the install via the terminal and that seems to have done the trick.  I'm at a login screen at the attached monitor. 
Next thing get some audio out of the attached schitt-dac.

Great to hear, let me know how you go.
 

I also installed roon-bridge (via the command-line, after installing curl) that worked, and I'm listening to some music right now. The schitt dac shows up 3 times in alsa but that's kind of expected behaviour for this dac, don't know why but picking the first one (hw 0,0) did convince the thing to output some audio to my computer speakers.
Will put the pc back in the living room audio set next week somewhere to listen seriously to the quality.
Before this I was using the same pc with Win10 and J-River but got hooked to roon and never looked at J-River again.

Regards,
Edwin.
