I have been trying to set up ardour, but jackd doesn't start in real-
time mode. I made an os definition that replicates this issue when I
use a VM.
I asked the gnome and gdm IRC and found out gdm loads the gdm-password
pam config, which seems untouched by pam-limits-service. My
/etc/pam.d/gdm-password (which should be the default) is attached.
