Lock screen stop working

Asked by Andrey Bondarenko on 2011-02-16

I suddenly unable to lock my KDE session in Kubuntu 10.10 (kdebase-workspace 4:4.5.1-0ubuntu8).

Right after login LockScreen is working, but after some time it stop working. Actually not only LockScreen, but krunner also doesn't start, so no command line. I'm writing about LockScreen, because it is easier to reproduce.

If I issue the following command, right after login:

$ qdbus org.freedesktop.ScreenSaver /ScreenSaver Lock

the session locked normally, but after some time the same command gives:

$ qdbus org.freedesktop.ScreenSaver /ScreenSaver Lock
Error: org.freedesktop.DBus.Error.NoReply
Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

I don't know much about D-Bus usage in KDE4. Can anybody give me an advice how to resolve or further debug the issue?

It looks like krunner bug, it is probably hang. I have found that, manually killing krunner and restarting it resolves the problem, at least for some time. I'm going to check krunner bugs. Thanks all.
