--- Comment #8 from mirandir@orange.fr 2011-10-30 04:35:13 PDT --- Sorry for the delay, I haven't had time to work on this sooner.
The "freeze" seems to begin to (ramdomly) happen after that gnome-screensaver switches off the screen.
As Archlinux don't provides debug packages, I must recompile some packages, and I have an error when I try to recompile X, I'm trying to solve that.
But the gnome packager provides some debug packages for gnome, so I can have a backtrace when the problem occur.
I don't know if it's usefull, maybe I should open a bugreport on the gnome-shell bugzilla too ?
