qdbus org.kde.ksmserver /ScreenSaver Lock

Stefan Becker 2013-03-18 13:51:27 EDT
This seems to be a KDE 4.9.5 -> 4.10.1 configuration update problem. I've now updated my second Fedora 18 system and everything went fine: there is "Global Shortcuts"/"The KDE session manager" and that has the "Lock Screen" action with the default CTRL-ALT-L. So on that system it works fine.

I removed the workaround on my first system and fixed the configuration instead:

- run "kbuildsycoca4 --noincremental"
- open System Settings -> Global Keyboard Shortcuts
- "KDE component" dropdown: if you still have "kscreenlocker" in the list, select it, then choose from the "File" dropdown "Remove component" to remove this obsolete entry.
- open the "KDE component" dropdown: if you don't see "The KDE Session Manager" *PLEASE* make sure to SCROLL DOWN the scrollbar on the right hand side to the BOTTOM! (on my machine "The KDE Session Manager" is the last entry)
- Select "Lock Session" and tick the "Default" choice to reset the default to CTRL-ALT-Ls

(In reply to comment #22)
> comment 11 doesn't work for me, because I don't have "Global Keyboard
> Shortcuts/Session Manager" in my system setting.

Found a workaround:

- from command line "qdbus org.freedesktop.ScreenSaver /ScreenSaver Lock"
- add Custom Short Cut:
* New -> Global Shortcut -> D-Bus Command
* name: "Lock Screen"
* Trigger: CTRL-ALT-L
* Action
- remote application: org.freedesktop.ScreenSaver
- Remote object: /ScreenSaver
- Function: Lock

In this case, it is likely you were experiencing a temporary issue, which rectified itself.
