That's not what I meant. I'm interested in whether the problem occurs
with the nVidia GPU as well using the modesetting driver and glamor.

All you should need in /etc/X11/xorg.conf is something like:

Section "Device"
        Identifier "Device0"
	Driver "modesetting"

However, it occurred to me that glamor might not work on a GTX 970
unless you're using very recent upstream snapshots of Mesa and the kernel.
