Also, I have discovered that xsetwacom can no longer find my wacom tablet at all. --list devices returns nothing, and trying to set the binding area for any of it’s touch inputs returns “cannot find device”.
libwacom is up to date, wacom dkms is up to date, xf86-input-wacom is up to date, and wacom-utility can’t find a tablet.

Is there a working image of manjaro xfce with nvidia nonfree from like… 5 months ago?

KDE somehow detects the tablet still.
