Dell XPS 13 9310, Display issue after installing update!

Hello,

My Dell XPS 13 9310 with the 11th generation i7 processor, Intel(R) Iris Xe Graphics, and preinstalled Ubuntu 20.04 (Kenel 5.6.0.1022-oem) just arrived yesterday. After installing the suggested updates, I restarted the laptop and it has been restarted with flickering/tearing (horizontal lines) and I cannot see and do anything. Then it goes into GNU GRUB options.
I restored the system into the original configuration and have updated firmware to the last version (Ver. 1.1.1) and after installing the updates, it has still the same issue.

I have tried Ubuntu 18.04 and after installing updates the same issue came back again!

Thanks in advance for your comments!
