Comment 5 for bug 923644

Okay. So there are two problems to this. #1 Totem incorrectly uses xtest to send ALT every 30s even though other APIs (dbus) are available to prevent screensaver-activation. #2 totem does this, when not in focus.

Upstream insists on using xtest as a fallback if no APIs (xscreensaver or dbus) are available. Totem 3.0.1 has two bugs that seem to be fixed in 3.2. #1 xtest should only be a fallback and not be used if dbus is there (in Ubuntu 11.10 and 12.04 both are used) and #2 totem in background shouldn't try to disable the screensaver ([1]).

Precise will not ship the fixed version of totem because of the new clutter dependencies, so this needs to be fixed in Ubuntu if HUD is going to be shipped.
