Currently my tablet is in absolute mode. In this mode, when the screen does not have the same proportions as the tablet, for example, drawing a cercle may result into an oval.
I am trying to configure my tablet so it acts like a touchpad or a mouse (relative mode).

Bus 008 Device 002: ID 5543:0005 UC-Logic Technology Corp. Tablet WP8060U
...The tablet is natively supported, but I haven't found a way to change its mode to relative. I also tried by installing wizardpen and modifying /etc/X11/xorg.conf.d/70-wizardpen.conf but without success:

I decided to start over. I removed wizardpen and tried with the already installed evdev.
Now I have half of the solution:
1) Get a list of input devices
$ xinput list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ Microsoft Microsoft 3-Button Mouse with IntelliEye(TM) id=10 [slave pointer (2)]
⎜ ↳ UC-LOGIC Tablet WP8060U id=11 [slave pointer (2)]
⎜ ↳ UC-LOGIC Tablet WP8060U id=12 [slave pointer (2)]
⎜ ↳ PS/2 Mouse id=15 [slave pointer (2)]
⎜ ↳ AlpsPS/2 ALPS GlidePoint id=16 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Video Bus id=7 [slave keyboard (3)]
↳ Power Button id=8 [slave keyboard (3)]
↳ Sleep Button id=9 [slave keyboard (3)]
↳ Lenovo EasyCamera id=13 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=14 [slave keyboard (3)]
↳ Ideapad extra buttons id=17 [slave keyboard (3)]2) Get a more detailed list about each "UC-LOGIC Tablet WP8060U" (id 11 and 12):

Mode: relativeIt is now in relative mode, but the displacement of the cursor is to big compared to each movement on the tablet. So I am going to take a look at the props of this device:
$ xinput list-props 11

Evdev Drag Lock Buttons (275): 0I am going to change the value of "Device Accel Constant Deceleration" to 4:
$ xinput --set-prop 11 'Device Accel Constant Deceleration' 4Now in relative mode, the drawings are more proportionate, but when drawing a square on the tablet, the result on the screen looks a bit more like a vertical rectangle. The table has a resolution of 1024 x 768 and seems to be mapped as a square on the screen, so the vertical strokes are longer than the horizontal ones. To change the mapping proportions I will modify the "Coordinate Transformation Matrix" by changing the value that affects the vertical positionning with a ratio of 768 / 1024 = 0.75:
$ xinput --set-prop 11 'Coordinate Transformation Matrix' 1 0 0 0 0.75 0 0 0 1The result is viable, but there are several shortcomings left:
1) When I do this for example :
- Move the cursor from the left of the screen to its right by moving the stylus close to the tablet
- Lift the stylus high and bring it back to its starting point.
The cursor moves back left half of the screen instead of staying still on the right.
What should I do to maintain the cursor still when I perform the above actions?
2) The above commands has to be executed manually each time I plug the tablet to the usb port.
How can I automatize the following configuration on plug in a system wide manner?
$ xinput list
$ xinput list --long 11
$ xinput --set-mode 11 RELATIVE
$ xinput --set-prop 11 'Device Accel Constant Deceleration' 4
$ xinput --set-prop 11 'Coordinate Transformation Matrix' 1 0 0 0 0.75 0 0 0 1Offline
What should I do to maintain the cursor still when I perform the above actions?
The problem has not been resolved yet but there is a way around. When there is a need to do precision work, the cursor is moved using the tablet, but when there is a need to move the cursor on a great distance, the mouse and the touchpad are more efficient than moving back and forth the stylus on the tablet.
How can I automatize the following configuration on plug in a system wide manner?
A xorg configuration can be placed in /etc/X11/xorg.conf.d:
61-UC-LOGIC_Tablet_WP8060U.conf:
