- - VGA
- - HDMI
+ - two mouse pointers on screen on booting with on dual monitor setup, One
behave normally second is stuck just animate synchronously with first one.
+ - The presence of second mouse pointer results in mouse pointer trailing
artifacts and screen artifacts under mouse pointer, rendering desktop unusable.
+ - On Ubuntu Mate the second mouse pointer appear on a screen edge, and on
Regular Ubuntu it appear somewhere on one of the two screens.
- 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.
+ Affected Systems
+ ----------------
+ - Tested on Both Ubuntu Mate and regular Ubuntu, both version 19.10 and 20.04

- 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
+ Issue reproduction

+ - booting with two monitors connected on affected system,
+ (connecting second monitor after login screen -lightdm greeter ... - will
prevent issue appear)
- 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
+ Workarounds
+ -----------
+ - booting with only one monitor connected, and connect the second one later
after log-in screen appear.
+ - on booting with two monitors on Ubuntu Mate: Disabling Marco - Adaptive
compositor to "No Compositor" will solve pointer trailing and screen artifacts,
(but the second mouse pointer remain outside screen.
