I don’t think I have enough knowledge to solve this or say anything for certain, but I wonder if the power button is treated as an external keyboard and is getting ignored in tablet mode?

I’m using an app to use my Android phone as a webcam, which works great (good low light performance!) provided I can stand it up somewhere above my laptop screen (finicky). You can accidentally knock it over. Might be worth considering if you don’t use the camera much - otherwise an external one will probably attach better and he more stable

Not recommending against RustDesk - it is a very cool project - but regarding the “Why?”, you could use a VPN or something like Tailscale which has MagicDNS that’ll resolve hostnames of computers to their local IP address. You can use this with GNOME’s RDP server to remote in from another device pretty easily.

PairDrop(dot)net is a fork with a bit more features

I believe they’re available as backup but re-calibrate themselves with GPS coordinates if available. This is not a problem when GPS jamming is used but becomes an issue with spoofing - the pilots need to monitor for it.

I think they talk about it in this video by flightradar24 somewhere: https://youtu.be/4dG_Whxzdkk

Strange. The default keyboard works wonders for me but doesn’t automatically pop up. Are you able to swipe from the bottom edge of the display to make it pop up?
