Upgrade from 3.4.3 to 5.1.3: habpanel shows black screen

OH 5.1.3 in docker.

I migrated form 3.4.3 to 5.1.3

I changed the IP address in the kiosk file; however, all I get is a blank screen.

The rpi acting as a display had buster on it; and chromium v90; so after a couple of hours mucking about, I decided to do a new install, with the 32-bit trixie image.

To my surprise, or may be not at all; I also got a black screen.

I can startx the terminal and launch:

/usr/bin/chromium \
  --disable-gpu \
  --use-gl=swiftshader \
  --disable-dev-shm-usage \
  --incognito \
  --enable-logging=stderr \
  --v=1 \
  "http://192.168.9.10:8080/habpanel/#/view/TrialPanel?kiosk=on"

= black screen

the OH GUI loads on 8080, adding habpanel says no default panel set. calling the full URL = black screen.

My point: this was working before the upgrade. It renders in any browser; not on iPhone; same message “No default panel configuration! sing in with the main UI to enable editing in HABpanel and set a default panel”.

Beats me, can’t find the setting :frowning: And why was it working before.

Any hints appreciated.

Yes, I consulted the docs, could save it under another name; but no luck in setting the default.

3.4.3 -> 5.1.3 = 2 hours; black screen on HABpanel, and none the wiser after 10 hours of trying

Since you use a commandline to launch Chromium you could try adding --remote-debugging-port=9222 and then using another Chrome-based desktop browser on http://<your-device-ip>:9222 to do some remote debugging and check for errors in the Console, maybe you’ll get some clues from that. Disclaimer: It’s been a while since I did that and I don’t know if it still works.
