KDE lock/unlock session problem with screen saver timeout [ kdesktop_lock ]

Hi All,

I'm using the latest kdebase rpm for my distribution RHEL 5 (kdebase-3.5.4-20) and I set the x screen saver timeout off with 'xset s off' and with xorg.conf configuration (removing DPMS option) but every time I lock/unlock the session I get the x screen saver timeout set to 310.

Do you have any idea to fix this annoying problem?

Thank you in advance for any help/suggestion!!

KDE Unlock problem

Hi Guys,
I have the same problem and it is very dangerous! I'm using KDE 4.4.5 on top of Ubuntu 10.04. Installed it from PPA repositories. Having problems unlocking locked session.
When using openGL screen savers, I can't even see unlock dialog box.
When using normal secreen savers like acquarium, I can see the unlock dialog box, but sometimes no matter how many times I try, I cannot unlock session it says "Unlocking failed". I have no choice than restarting my laptop and loosing all my work (Which makes me remember my bad days in windows!).
Pressing Ctrl+Alt+F2, logging in trough command line and running killall krunner_lock will not solve my problem. Becuase there is nothing named krunner_lock exist in my laptop!
qdbus org.kde.screenlocker /MainApplication quit DISPLAY=:0
qdbus org.kde.plasma-overlay /MainApplication quit DISPLAY=:0
will not solve the problem either. Because it says that it cannot connect to dbus server, even when run as root.
Any suggestion?
I can not let my computer go on and lock because then I'm not sure that I can unlock it after!

For now decided to run this:
sudo chown root:root /usr/lib/kde4/libexec/kcheckpass
sudo chmod 4755 /usr/lib/kde4/libexec/kcheckpass
which I took from here.
Will come here and write if it changed any thing.

Rather drop the native KDE screensaver and download the latest standalone XScreensaver app - works for me...
