Many applications not launching

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:

blender: symbol lookup error: blender: undefined symbol: __glewXCreateContextAttribsARB

vlc:

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

Re: Many applications not launching

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.
(python:3471): GLib-GObject-WARNING **: 03:12:40.052: cannot register existing type 'GdkDisplayManager'
(python:3471): GLib-CRITICAL **: 03:12:40.052: g_once_init_leave: assertion 'result != 0' failed

Re: Many applications not launching

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.

Re: Many applications not launching

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.
