Comment 7 for bug 1516428

I've got the same problem.

While in Inkscape 0.91, the program creates hundreds of repetitive keys entries (repeats this kind of thing: "<Primary><Mod3><Mod4><Mod5><Hyper><Super>"), which makes the preferences file nearly impossible to edit), I have pressure sensitivity in 0.91, but not in 0.92.2 or 0.92.x branch (where it creates hundreds of semicolons in those places... and doesn't save when I set 'screen').

Copying the old 'devices' group from the 0.91 prefs over into the 0.92.x preferences solves the issue. Inkscape did see that the tablet has pressure sensitivity.
