Sure, that's why I'm most interested in the awakening one (I didn't really make it clear in the first mail, sorry. I haven't really slept a lot last night). The idea is that an hypotetical AboutToSuspend signal would be streamed by the daemon in the userspace (g-p-m or PowerDevil). That's also why I was skeptical about the possibility of having the possibility to interrupt suspension, since I believe this really belongs in the workspace. The Awakening signal instead would be more useful and less dangerous. Let's say that, in the end, the best solution for everyone could possibly be just adding the Awakening signal. > > Richard. > -- ------------------- Dario Freddi KDE Developer GPG Key Signature: 511A9A3B
