Hello everyone!
I'm looking for a way to change the plasma theme and the color theme from the command line or from a python script.
I need to switch back and forth a dark plasma and color theme for night operation to a bright plasma and color theme for daylight operation.

I guess I have to tinker with d-bus commands, and I played for a while with qdbus and qdbusviewer, but couldn't find any solution this way.

Any clue?
Thanks in advance

You will need to stop Plasma, ( kquitapp plasma-desktop ), wait for it to close, then use "kwriteconfig" to update the appropriate key in "plasmarc" located in ~/.kde4/share/config

Thanks for the answer!
I need one more hint, if possible...

Looking inside ~/.kde/share/config/plasmarc I can't find nothing related to colors or theme. Here's what is there:

$ cat ~/.kde/share/config/plasmarc
[$Version]
update_info=plasma_popupapplet_fix_groups.upd:PlasmaPopupAppletFixGroups2

[Theme-amarok]
name=Amarok-Mockup

I looked inside other (apparently) plasma-related files, but couldn't find anything related. Even grep-ing all the files in that directory I couldn't find any file containing my color theme name or my plasma theme name.

Any hint?

regards
gerlos

Plasma Desktop itself uses a key "name" in the group "Theme" in "plasmarc" to store the setting. If you wish to use the default setting, simply remove the key.

( For the Oxygen theme for instance, the name is "oxygen" so the key's value is "oxygen" - quotes removed )
