One wonders: I have X/KDE set up to lock itself after some period of inactivity. About 20% of the time it doesn't. I'll come back four or five hours later, and I don't have to enter my password to begin using the computer. Imagine if sudo just forgot to ask for my password sometimes! Anybody know what causes this? Xorg 7.2.0, KDE 3.5.6, Kubuntu 7.10. -todd
