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?
There’s an example service file in the Plasma-systemd-integration repository.
I’d wager you might be able to just run this, but it might not work.
systemctl enable kdeconnectd
Upvote for KDEConnect. Works on my 2 Manjaro Installation and also it’s running on Mint with cinnamon without any problems.
The android app is also great for typing on the go :)
But does that work in game mode? OP already mentioned that limitation as why they are not using KDE Connect.
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.
I think you can use usbip to share any usb device that is connected on your linux desktop to steam deck (or any other pc) over the same network.
