Hi, I just assembled my V4 kit, burnt the buster RC2 image and… plugged everything.

I have a screen plugged on HDMI 0 of the PI, and when booting I see the raspbian booting screen, and the Zynthian UI starts alright on the zynscreen, but then I’m just left with a black screen with a cursor on my monitor.

Plugging a keyboard, I could use Ctrl+Alt+F1 to 7, and I saw the various ttys, but where the GUI environment should be here (tty7 usually), there’s just nothing.

I know an X server is running, because I could log via `ssh -Y` with another computer, and start graphical apps (like ZynAddSubFX).

Is there no desktop environment installed by default on the image?

OK ^^ so then it’s perfectly normal.

I just wish it would have been made clearer on the docs 😕 because I thought the default raspbian gnome was still there…

But then I fail to understand: how can access e.g. the ZynAddSubFX UI to create patches? Zynthian UI will only show pre-made patches, and starting ZynAddSubFX via `ssh -Y` will create a new instance, not show me the UI for the ZynaddsubFX already running in one of the layers.

If you ssh -Y into the zynthihan and then launch zynadsubfx from the zynscreen menu, does the UI load on the PC? It used to.

I tried that yes, but the UI didn’t start on my laptop. I guess the Zynthian UI starts it in a different session that the ssh one.

Do you have an Xserver running on your laptop for it to connect to? Like Xming or VcXsrv?  
Also, did you connect before you ran ZynAddSubFX?
