Issue Description
-----------------
Intel NUC5CPYH has two video outputs:
- VGA
- HDMI
When booting with two monitors after lightdm on screen appear two mouse pointers
- one on center of the "viewport" between two mointor - this one can be handled on the screen
- one on the lateral edge of one of the monitor. - this imitate the behaviour of first without moving
Note: on xinput there is only one master pointer, so it should not be two on screen.
Workaround
----------
To solve this issue an workaround is to boot PC with only one monitor, and connect the second one only after logged-in and OS has finished loading
Ubuntu Mate 19.10 Issue aggravation
-----------------------------------
On 19.10
- with compositing window manager
- boot with two monitors to have two pointers
- use Marco - Adaptive compositor
The mouse start to flicker on screen alternateing between positions, leaving trails and screen artifacts make system unusable
Workaraound - use Marco - No Compositor
Note
----
This system also has another mouse pointer bug
