Lol I don’t know why people are hating this. It’s cool, looks more European. Do you have more for other states? There are some way crazier flags flying in the US.
These LEDs are not shift registers. In fact, if you look closely, there’s no input and output pin, only one data line. That’s because each LED in this strand is pre-addressed from 0 to 100. Whenever it receives the NeoPixel data, it picks out the n’th color data (matching to its pre-address) and displays that. You cannot change the pre-address, its fixed permanently - or at least, we have no idea how to re-address it.
Gnome 3 has an option to keep one display fixed when changing workspaces… Also most window managers allow you to keep certain windows on all workspaces, maybe that will help?
Thinking that the TV is periodically connecting and your desktop environment is trying to switch to dual monitors before quickly losing the TV connection.
