Since the earliest versions of KDE 3, I've encountered problems with kdesktop_lock hanging on one of my systems. I've always either worked around it or switched to xscreensaver but as it has persisted through recent upgrades, I figure it's about time to make mention of it. Every second or third attempt at locking my screen will fail and I must kill the kdesktop_lock process in order to restore functionality. I am then privileged to another two or three uses before repeating this procedure. As I use kdesktop_lock on many other machines without issue, the one unique characteristic of the machine which this problem plagues is its dual-monitor configuration using xinerama. Noteworthy here is the fact that many of the screensavers available for use by kdesktop_lock will crash the X server when activated. Obviously, I tend to avoid those. As mentioned, the problem is apparent on varying versions of kde, though I'm currently using the kdebase-3.1-15 rpm from RH9. Video chipset is Cirrus Logic 5480.
