nvidia - Stuck in Login-loop after installing drivers for GTX 1060

After I solved this problem, I was able to go to the login screen.
My problem now is that I am stuck in a login-loop...

Details about what led to the login-loop problem:

• bought a Nvidia GTX 1060


• installed the gpu with driver nvidia-381 on Ubuntu 16.04

Note:

• I can access the TTY while I'm in the login screen


• The login-loop: I can login perfectly but after about 5-10 seconds or so, I get thrown back to the login screen


• Most of the time this problem is solved, when you uninstall the nvidia drivers but I can't uninstall the them because without it I get my first problem again and with that blackscreens or the low-resulution mode


• Secure boot is already disabled


• Till now I haven't blacklisted nouveau, but I will try that

I also looked at this post and some of the links there

After quite some hours of research I found this guide, which helped me solve my problem.
I don't exactly know what caused my problems but now I everything works just fine.
