DisplayLink Forum - View Single Post - Artifacts around mouse when using DisplayLink with Nvidia drivers

Please, hear my plea!

I'm seeing artifacts around my mouse when using DisplayLink with Nvidia drivers. I don't know what else to do. I have done everything you can imagine.

Here's a video of the problem: https://www.youtube.com/watch?v=vVwa-cVU_cA

This only happens with Nvidia driver. If I use Nouveau, the artifacts are gone.

I have three monitors:
- 1 in HDMI
- 1 in MIni Displayport
- 1 in USB using Plugable UGA-165 with DisplayLink

The mouse flickers and shows artifacts in all screens if DisplayLink is connected. If I disconnect it, the artifacts are gone.

I have added this options evdi initial_device_count=1 to /etc/modprobre.d/evdi.conf as an attempt to solve it. If I add evdi do /etc/modules I can't boot.

Linux distribution and its version: Ubuntu 18.04
Linux kernel version: 5.1.15
X11 version: 1.20.1-3ubuntu2.1~18.04.1
Desktop environment in use: GDM3
Nvidia Driver version: 430
Driver version: 5.1.26
DisplayLink service status: up and running
EVDI service version: 1.6.1
