Hello after i activated my nvidia gpu and disabled my intel gpu on my archlinux laptop many applications including also some display managers fail to start.
Some logs:
blender:

What does this mean? What, specifically, did you do?

I have a similar problem in PyCharm community, although I don't have nVidia card:
import matplotlib.pyplot as plt
Backend Qt5Agg is interactive backend. Turning interactive mode on.
Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.

That looks to be a completely different cause, and in your case it presents the solution:
Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.

It fixed the problem. Strange, because it had worked before without this env var. Maybe, it's because something changed after Gnome components updates on 2018-07-19.

Like I said I changed my linux modules to use my nvidia gpu instead of my intel integrated GPU on my Laptop.
But after I changed this, I got these errors in some applications like blender, vlc, eclipse, etc. but many applications still work.
It's very strange.

How what specific commands were used? What packages were installed / removed? What config files were altered?
Edit:
Also the output of dmesg, the contents of Xorg.log and the output of lspci showing the GPU's in the system.
