Comment 36 for bug 403421

A more technical addition (this is a bug report, after all):

When looking at the raw input values from the tablet with xidump, in absolute mode, I get the pen pressure and x and y coordinates over the whole range of 0,0 to ~14000,9000 (forgot the exact values).
When in relative mode, the coordinates only ever show the increments between reads, so positive and negative(!) numbers in the range up to ~+/-40 or so. More importantly, in relative mode, I don't get any pressure information, even in the raw data. I do get a "button 1 up/down" event, though, so I don't understand why I can't draw at all in Inkscape (even with pressure sensitivity switched off).

I hope, this might help someone who understands more about it, to fix the bug.
