control: reassign -1 xserver-xorg-input-all I have a ThinkPad Yoga 12, which has a touchscreen. In a normal session, I can move my finger on the touchscreen, and the cursor will follow the finger. Just like it is supposed to.
However, I now plug in an external display. By default, it is supposed to be physically located to the right of my primary display, i.e., my desktop is now twice as wide; the left part is on my built-in display, the right part on the external one. In this situation, the code that computes the cursor position from my finger position on the touchscreen is wrong: when I move my finger from the left edge to to the right edge of my primal display, the cursor moves from the left boundary to the right boundary of the entire virtual desktop. In particular, if I touch the screen in the right half, the cursor appears on the other display. As it turns out, this is not a Mate issue: I see the same effect with a KF5 Plasma desktop. +++-============================-=============-============-========================================================= un xserver-xorg-input <keine> <keine> (keine Beschreibung vorhanden) un xserver-xorg-input-2 <keine> <keine> (keine Beschreibung vorhanden) un xserver-xorg-input-2.1 <keine> <keine> (keine Beschreibung vorhanden) un xserver-xorg-input-4 <keine> <keine> (keine Beschreibung vorhanden) un xserver-xorg-input-7 <keine> <keine> (keine Beschreibung vorhanden) ii xserver-xorg-input-all 1:7.7+16 amd64 X.Org X server -- input driver metapackage ii xserver-xorg-input-evdev 1:2.10.2-1 amd64 X.Org X server -- evdev input driver un xserver-xorg-input-evtouch <keine> <keine> (keine Beschreibung vorhanden) un xserver-xorg-input-joystick <keine> <keine> (keine Beschreibung vorhanden) ii xserver-xorg-input-libinput 0.19.0-1 amd64 X.Org X server -- libinput input driver ii xserver-xorg-input-mouse 1:1.9.1-1+b1 amd64 X.Org X server -- mouse input driver ii xserver-xorg-input-synaptics 1.8.3-2 amd64 Synaptics TouchPad driver for X.Org server un xserver-xorg-input-tslib <keine> <keine> (keine Beschreibung vorhanden) ii xserver-xorg-input-vmmouse 1:13.1.0-1+b1 amd64 X.Org X server -- VMMouse input driver to use with VMWare ii xserver-xorg-input-wacom 0.30.0-1+b1 amd64 X.Org X server -- Wacom input driver
