In addition, nvidia-xconfig doesn't see the GPU and had to be manually entered in xorg.conf.  Finally, the audio is choppy/laggy.  All of that is stopped when I disable NVIDIA driver with NVIDIA Prime.

The error "PKCS#7 signature not signed with a trusted key" keeps getting spammed and it won't even let me get to SDDM.  Also, NVIDIA Prime doesn't seem to work with nvidia-340 because I still experience the same problem.
