Maybe Pardus 2008.1 does this, but I haven't seen it yet. Oftentimes, I boot up the computer and don't log in right away as I am doing other things, and I notice the log in screen is still visible well after 30 minutes have passed. With other distro's there is usually a period of time when the display turns off or suspends, and with the move of the mouse or a click of the keyboard, resumes it. This would be just a little wish function, and important if you have a CRT type display. KPowersave does work great after logging in.
