Document DE's that handle monitor mapping (KDE, more?)

[gonX]

Problem: DE sees tablet and maps tablet for you. However, since OTD also maps the tablet for you, the common problem is along the lines of "tablet only reachable in the upper left" or similar.

The fix is to either map the DE to the full monitor layout (OTD devs: can we work around this?), or mapping to the entire monitor layout in OpenTabletDriver.

This can likely happen on Windows too in some setups, so this likely needs to be included in a generic FAQ.
