Version:            (using KDE KDE 3.5.4)
Installed from:    Debian testing/unstable Packages

I have configured kscreensaver to start automatically after a 5 minute
delay. It works all right until I take over the desktop remotely, using
the x11vnc. When viewed through vnc, when I release the mouse, the
screensaver starts immediately. (It used to work all right a couple of
releases back, I'm not sure when, I didn't use vnc for many months now)

Yes,
I also have to disable the screensaver when I take over my home computer 
running x11vnc 0.8.3 remotely from work with tightvnc_viewer.
I have Mandriva Linux with KDE 3.5.4.

Karl Runge thinks it may be a bug in kdesktop_lock:
http://www.karlrunge.com/x11vnc/#faq:
Q-42:  Help! x11vnc and my KDE screensaver keep switching each other on and off 
every few seconds.  
 This is a new (Jul/2006) problem seen, say, on the version of KDE that is 
shipped with SuSE 10.1. It is not yet clear what is causing this... If you move 
the mouse through x11vnc the screensaver shuts off like it should but then a 
second or two after you stop moving the mouse the screensaver snaps back on. 
 This may be a bug in kdesktop_lock. For now the only workaround is to disable 
the screensaver. You can try using another one such as straight xscreensaver.

I have traced this down to a DPMSInfo() call in the kdesktop_lock

Even though there has been mouse or keyboard input to wake kdesktop_lock
up and cause it to turn off the screen saver, kdesktop_lock (or a
respawned process of it) checks DPMSInfo() and if it sees the Monitor
is in a low power state ("standby", "suspend", or "off") it turns on
the screensaver again.

I'm not sure if this is the desired behavior of kdesktop_lock or not to
discard the recent mouse/keyboard input information...

I have put in a workaround to x11vnc for this, the -nodpms option where
it will keep the Monitor in the DPMS "on" state whenever VNC clients
are connected.

i can confirm it too, and i use kde's own vnc tools (krdc and krfb).

so for now the only real fix is to revert patch like mentioned in bug
142308?

As far as I can tell, it's gone. I checked it in ubuntu hardy. (It looks
OK for KDE 3 also in hardy)

Actually -- what a coincidence, it's amazing -- I just had this bug with
my wife's kubuntu hardy's KDE3. Not that I'll reopen this bug though,
before seeing it with kde4 first.

Oops. And on the second try the bug happened again. If I move the mouse
out of vncviewer, the screensaver kicks in immediately again.

However I think this is an Xorg bug more than a KDE bug. It's X which
decides when to let the screensaver kick in, AFAIK.
