Hello there,
I am using the following Acer Swift 3 Laptop
- NTB Acer SF315-41-R9R4 FHD
- Ryzen 5
- 8GB
- 512GB SSD
- Ubuntu 20.04
Issue: When I boot the laptop the screen (randomly) goes white (Sometimes nothing special/bad happens). The screen doesn't go completely white in the beginning. It starts with a white ellipse in the middle and then more and more of the screen turns white, till in the end it looks like this:

A kinda similiar Issue arises, when i tilt the screen. This also only occurs sometimes, but results in this fancy "noise" image:

I hope it's "only" a broken eDP cable. Can someone confirm this assumption/ Knows how can I confirm this assumption?
Thanks in advance for any help.
