looks successful.
does a "lancelot" process run afterwards and is there a "qdbus | grep -i lancelot"?

Code: Select all

$ qdbus | grep -i lancelot
 org.kde.lancelot

(if you re-add the plasmoid to the panel or desktop or whatever) - do you now get places etc.?

unfortunately no, any other idea? thank you for your patience guys.

I notice a number of applications aren't found by Lancelot. Are Krita, System Settings and KInfoCenter installed on your system?

bcooksley wrote:Are Krita, System Settings and KInfoCenter installed on your system?

yes they are

Can you please delete the entire contents of /var/tmp/kdecache-$USER/ outside of KDE?
Also, are you able to start one of those applications outside of Lancelot?

bcooksley wrote:Can you please delete the entire contents of /var/tmp/kdecache-$USER/ outside of KDE?

already done and done again now terminating the kde session, also killing kdm and removing /var/tmp/kdecache-$USER/* from tty1 as root.

Yes, both from kickoff and lancelot, with alt+f2 and other methods. Everything is working fine here except that Lancelot still doesn't show places. Are you sure that there aren't other files in my home used by Lancelot?

I'm afraid there are none that i'm aware of. Places data should be retrieved from the same place used by Dolphin and other applications (where I assume it is displayed correctly).

The only thing that I can say is that Lancelot uses the "kfileplaces/bookmarks.xml" to find out which items to show the places. It skips only the items marked as "IsHidden".

What happens if you move the bookmarks.xml somewhere else (ensuring that no kde application runs beforehands)?

It solved the problem! thank you so much!

No problem

Did you archive the file?
viewtopic.php?f=67&t=120809#p308892

There might be a bug in lancelots parsing if
a) the file looks correct
b) places were shown in dolphin (that should use the same file as all of KDE)
