Hello, I am using Wacom tablet on Ubuntu 15.04 and latest (0.4.8) version of xournal from Ubuntu repository.
To make boundaries of tablet surface to match size of xournal window (opposite to the situation when tablet surface matches entire desktop) I run xsetwacom command to adjust "area" property reported to driver. It works well and allows to use entire surface of the tablet for drawing. This trick works fine but when (for reasons not discussed here) I have to move xournal window or resize it, mapping needs to be repeated to adjust to new coordinates of the xournal window withing the desktop. The mapping script performs calculation based on *original* (default, fresh) settings of the tablet's "area" parameter which are no longer in place after previous run of the script. To overcome this issue I need to disconnect the tablet, connect it back, and re-run the script... but I really don't like the "physical re-connect" component of the process. I came up with using an approach to "emulate" USB devise unplug/replug prior calling to my script... and it works almost fine: it sets "area" parameter back to default value (i.e. 0 0 15200 9500) but it *reassigns mapping of input devices* so xournal cannot use "stylus" for drawing. It shows the cursor, but it that cursor doesn't draw. Here is an example of changed mapping: *Before:* $ xinput list ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Wacom Intuos PT S Pen stylus id=11 [slave pointer (2)] ⎜ ↳ Wacom Intuos PT S Pen eraser id=12 [slave pointer (2)] ⎜ ↳ Wacom Intuos PT S Pad pad id=14 [slave pointer (2)] ⎜ ↳ Wacom Intuos PT S Finger touch id=15 [slave pointer (2)] *After:* $ xinput list ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Wacom Intuos PT S Pad pad id=11 [slave pointer (2)] ⎜ ↳ Wacom Intuos PT S Pen eraser id=12 [slave pointer (2)] ⎜ ↳ Wacom Intuos PT S Pen stylus id=13 [slave pointer (2)] ⎜ ↳ Wacom Intuos PT S Finger touch id=14 [slave pointer (2)] Here mapping for stylus changed from device ID 11 to 13. My *question*: can I somehow signal xournal to re-evaluate input device mapping? Thank you. -- Simon
