@const @alexology I guess the SteamDeck battery would probably go empty very quickly with connecting an external display like that, but I don't know enough about the Wacom One (I never tested it). It would be interesting to-test for curiosity if someone have both.
Alex: Does the Wacom One you have can get power+data from only the USB-C? What Linux distro are you running? Does it have touch/palm rejection for mobile usage? Thanks.
