Title:
Touchscreen support with multiple screens: pointer location
proportional to all screens instead of the touchscreen only
Status in xorg-server package in Ubuntu:
New
Status in xserver-xorg-input-libinput package in Ubuntu:
New
Bug description:
Touchscreen support seems broken with multiple screens.
* Screen 1: Laptop touchscreen
* Screen 2: HDMI external non-touch screen (at the right of screen 1)
While touchscreen works as expected when no external screen is
connected, with both screens there is a touchscreen scaling issue:
Press at the very left of the touchscreen: the pointer matches your finger.
Now swipe slowly to the right: the more you progress, bigger the difference
between your finger and the pointer is.
Stop swiping at the very right of the touchscreen: the pointer matches the
very right of the non-touch screen.
See the enclosed drawing that illustrates the issue as well as the bug
report (added by apport).
