Thanks for those files. I can see two possible problems (which may not be problems but should be checked):

1. You are configured to use both the Nvidia driver version 410, and are asking Xorg to configure the old Intel driver. In theory this should be possible but OpenGL is really a very simple beast so it might be confused in the Totem window with both drivers being present. :(

2. The intel Xorg driver doesn't recognise your new Intel GPU:

[ 19.882] (WW) intel(0): Unknown chipset

So it might be a better idea to stick with the default 'modesetting' Xorg driver instead of selecting 'intel'. When you use the former you only need kernel+Mesa support for your new Intel GPU. When you use the latter you need kernel+Mesa support AND user space support (which clearly doesn't exist) in the intel Xorg driver. So I think you should remove this:

# Makes tearing in totem worse.
Section "Device"
  Identifier "Intel Graphics"
  Driver "intel"
  Option "TearFree" "true"
EndSection

and continue investigating using the 'modesetting' driver only.

P.S. How many monitors are you using?
