Same issue here with driver version 5.3.1.34.
Reinstalling the driver does not help. With previous kernel the system is working properly. |

Downgrade kernel as a temp solution
I had to downgrade to the previous kernel to get my second monitor working again.

In case anyone runs into the same issue I did whereby switching to 5.3.0-X kernel brought up the monitors ok but made it run super slow. Turning the laptop monitor on solved the issue per
https://bugs.launchpad.net/ubuntu/+b...15/comments/12 A superwide monitor is starting to look good on days like today! Last edited by Chrismb; 07-24-2020 at 01:33 PM. |

Any Update/ETA on fix for 5.0.42 kernel?
I'm not seeing any movement on this, should I be reporting to another channel (git, etc.)?

Hello,
Please make sure that you are not missing the tools necessary for the installation. You have to run following command prior to installing the newest driver: Code:
sudo apt install build-essential dkms Please give that a try and let me know if it helped. Best regards, Katarzyna

Hello, i have both packages installed and the driver version 5.3.1 is installed and working properly together with the older kernel 5.3.0-62. It stopped working with the delivery of the newest ubuntu 18.04 kernel version 5.4.0-42. I tried again to uninstall der displaylink driver. Reboot with the newest kernel. Install all updates. Ensure that build-essential and dkms is installed and tried again to install the displaylink driver as described in article 1944022-how-to-install-displaylink-software-on-ubuntu-20-0 with the same result. If i switch back to the older kernel it directly start working again. It seems to be that the driver is incompatible with the actual ubuntu 18.04 kernel. BR Stefan |

I get the same issue as the people above.
Came into the office and everything worked, but after installation off all pending updates there is no picture on the two connected monitors. |
