There are a number of good sources for valgrind suppression files: 1) The cockpit project: http://cockpit-project.org Suppression files are in the tools directory: https://github.com/cockpit-project/cockpit/tree/master/tools 2) Johan Dahlin's file for the Gtk stack: https://people.gnome.org/~johan/gtk.suppression 3) Daniel Trebbien's GNOME.supp project: https://github.com/dtrebbien/GNOME.supp At the time of testing, the cockpit project produced far better results against glib version 2.36.3 and so that is what is included. xvfb-run comes from Debian: https://anonscm.debian.org/cgit/pkg-xorg/xserver/xorg-server.git/tree/debian/local/xvfb-run
