I have a Dell XPS 15 9570 with a Dell WD19 Dock and on this Dock I have 2 Monitors. The internal Monitor of the Notebook is off but the Lid is open.
I have installed Ubuntu 20.04 LTS.
Everything is working fine, except the following Icon in the Top bar is blinking (Appearing and Disappearing). I don´t know what that is. It looks like a cord but the Notebook charging as expected.
It blinks sometimes in a faster and another Time in a slower speed -> Something between 2 - 5 Seconds.
The Dock are the complete Time connected.
Exact behavior: It's blinking when I have connected my Laptop to the WD19 Docking Station. It's not blinking when I connect my Laptop ONLY to the normal Power Cord or have NO connection to Dock and Power Cord. But it's also blinking when I connect to the Docking Station AND the normal Power Cord.
Do anyone knows what this means? And how can I stop this? It's really annoying when some icons jumping all the time left and right!
