What I’m trying to do:
Create a dashboard with a Raspberry Pi 4 and a Samsung TV.
What’s not working:
I’m seeing some really weird video corruption with the Pi4. The cursor is fine, but starting any applications causes some (shredding?) of everything but the cursor.
What I’ve tried:
- Adjusting video RAM allocation
- Applications: Firefox, Chromium, and feh, and all produce garbage on the screen. Cursor looks fine, though, even with everything else being nasty.
- Window managers: I’ve tried using xfce4 and matchbox window managers, and I get the same result.
- Different monitors: I’ve tried a Samsung monitor, a Dell monitor, and a cheap little 1200x800 display from Amazon.
- Different cables
A little more about the app config:
- Using docker-compose to run 3 containers.
- One is proprietary stuff, unrelated to framebuffer weirdness. No special privs, just running an app in a container, periodically writing to resin data volume.
- Second container is running a Flask app
- Third container is dedicated to the display, running Xorg, matchbox, and Firefox.
- I’m using the
balenalib/raspberrypi4-64-ubuntu-python:3.7-bionicbase image for all containers.
