Yep, I've used both. Desktop mode isn't exactly there yet, but hopefully with the general availability it will get with Android 17, it'll smoothen out. As for the Linux terminal I ended up sticking with a fork which provides a few extra features (https://github.com/outlawsanzhang/koiTerminal)

I have a samsung too, I only really need the dex mode in so far as I need the wired external screen support. Gonna run terminal or vnc fullscreen anyway
