Mouse cursor jumps to other screen

[gavine99]

I'm also experiencing this issue on a Dell XPS 15 9560 laptop with a Dell D6000 dock. Laptop screen sitting to the left. 2 x HP L2445 monitors (1920 x 1200) middle and right.

When mouse cursor gets near right-hand-side of middle monitor or left-hand-side of right monitor it flickers and 'jumps' to the other monitor. Sometimes you can see it displayed on both monitors at the same time.

I just upgraded Ubuntu to 20.04 and so I had to update the DisplayLink driver to 5.3.1.34.

I also experienced this same problem with previous driver versions too. Displaylink driver version Release: 4.4 (17 Oct 2018) on Ubuntu 18.04 was the last driver version that didn't have this issue. And so it's been what I've been using since I got the laptop and dock. It was actually quite solid.

Something got broken after driver version 4.4 that causes this issue.

[ removed: I'm also getting sync drops with the newer driver too. Driver version 4.4 did not present any sync drops.]

added: I made a change and not getting the 'screen-drop-out' issues now. It seems like this thing was an old, old, old bug that still hasn't been remedied years later. Urgghhhh!!! Here are the notes I had in my old pulse audio /etc/default.pa file from years ago which I found and applied to my ubuntu 18.04->20.04 upgrade and seems to have fixed the intermittent screen-blank issue - so far, at least;

# GavinE - disabled because this was causing havoc with my D6000 dock! The audio would power off and shut screens of too!

So just the ridiculous mouse cursor issue left to fix it seems.

I've included logs from the support tool.

@DisplayLink, is anyone investigating a fix for this issue?
[edit: hellloooo?? Is there anybody out there? ]
