Mod-ui not starting

Software
1

I’ve got my zynthian a month now. I’m somewhere between hate and love. Hate is about that nobody bothers to write a decent manual for this thing. It’s probably brilliant, but I am not.

I try to get Mod-ui running. It stops after 2 seconds.
this is my error code: someone knows what i have to do?

Hi, @robert . Is the manual not clear enough for you:
https://wiki.zynthian.org/index.php/Zynthian_UI_Users_Guide

there’s a lot of things that are not described in the manual. It took me a couple of days to figure out how to get VLC working, for instance. I found out that I had to give my IP-number and add :1 to get the display. Might have been handy to put that somewhere.
Now I recently found out there’s an excellent VLC monitoring system in de zynthian configuration screen. That’s what I would like to read in a manual.

I’m trying to get ALO Looper working, but there is some magic involved in how it works, and nobody explains it properly. People explain it, but it’s incomplete and for a complete idiot like me, it’s incomprehensible.

So now I try to get Mod-UI working, hoping that ALO will work there. But Mod-UI doesn’t start. No idea why. Updating the system doesn’t help. Maybe praying does…
