<pre>OK, that's weird. Running sudo lsof /dev/dri/* doesn't get me any info about
the AMD card at all. I ran it at boot, when it's bound to vfio-pci (I set it up
to be that way at boot), then I ran it after unbinding it to that and binding
it to amdgpu, and then I ran it after attempting (and failing due to this bug)
to unbind it from amdgpu. All 3 times, I got these lines, which are referring
to my NVidia GT 740 (card0), and absolutely no lines that have anything to do
with Xorg or any other video card:
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
Xorg 597 root mem CHR 226,0 14346 /dev/dri/card0
Xorg 597 root 14u CHR 226,0 0t0 14346 /dev/dri/card0
Xorg 597 root 16u CHR 226,0 0t0 14346 /dev/dri/card0
Xorg 597 root 17u CHR 226,0 0t0 14346 /dev/dri/card0</pre>
