Re: [Linuxwacom-discuss] Wacom Intuos3 / Debian Stretch / Tilt values wrong in relative mode

[Jason G. <kil...@gm...>]

My apologies for the delay in replying --

When the tablet is switched to relative mode, it seems that all axes
(not just X and Y) begin emitting relative data. This appears to be
intentional, however: commit 49d7635e19 introduced this behavior,
noting that "the [axis value] builds up to the maximum and stays
there, even when the pen is lifted off the tablet." It links to
https://sourceforge.net/p/linuxwacom/bugs/156/ which suggests leaving
the pressure/tilt/etc. values absolute and only making the X and Y
axes relative. Why this suggestion was not acted on, I'm not sure...
Perhaps applications assume(d) that all axes were absolute or
relative, and so having a device "partially relative" caused problems?
I'm pinging the person who made that change to see if they can
remember anything, but its been this way for an awfully long time...
