Typing on the steam deck, no matter what method I use, is very slow. I have a linux laptop, but I obviously can't plug in the keyboard into the steam deck.
I was considering running KDE connect, but it gets closed in game mode. Could I run some kind of service in the background during game mode? Like is there some kind of systemd target for that?
systemd runs in game mode, the only difference from game mode to desktop mode is the window system. I have a systemd service for running syncthing in the background to keep some of my emulated save files backed up to my NAS.
The best thing is to just get a bluetooth keyboard. A Logitech K380 runs about 30 smackaroos. If they ever could be bothered to refresh the line for BTLE, that would be nice.
