Touch mostly worked fine. Xournalpp detected pen fine too. When I flipped the screen all the way back, things get wonky though and I have to reset the Wacom drivers. Sometimes it’s fine. I also had to write a xrandr script to rotate the screen to portrait.
In general, it’s mostly alright. I hear that Wayland is much better but I haven’t tried it yet. I do use the stylus quite often for marking up PDFs though and it works well.
