I don't think we will be able to fix the input problems in X.

SELinux is mostly used in a "targeted" way in Red Hat/Fedora, and thus does not protect GUI apps. It is a lot of work to create and maintain an SELinux policy for every GUI applications.

The second talk deals with DRM problems. This one was done to recap known problems and make sure we do not do the same "mistakes" with Wayland/Weston
