Hello everyone,
this is my first post in this forum and I'm from Germany, that's why my english isn't the best.

My problem is, that I recently downloaded Kali Linux and everything was fine. But after I executed the command "sudo apt dist-upgrade" everything was yellow an all texts and letters and stuff like that was white (pretty shitty contrast).
A few days later, I deleted the OS from my PC completely. But a few hours ago I gave Kali one more shot. After I installed it and booted it for the first time, it was as yellow as it was before.

Can anyone please tell my where the Problem is. I also installed the NVIDIA driver for Linux and executed the .run file, but it is still yellow and white.
