Title:
Mouse pointer flickers at using DisplayLink
Status in xorg package in Ubuntu:
Won't Fix
Bug description:
I have a three screen setup, the built-in laptop screen, a monitor
connected directly into the laptop via DisplayPort, and a monitor
connected via a USB DisplayLink Adapter.
What happens is that when a monitor is connected via the USB
DisplayLink Adapter, the mouse icon flickers only on the laptop screen
and monitor connected via DisplayPort (not on the monitor connected
via USB DisplayLink Adapter).
However, this is also reproducible if I either deactivate the built-in
laptop screen, or disconnect the DisplayPort connected monitor.
WORKAROUND: Disconnect the USB DisplayLink Adapter for the computer.
