Hi
I've recently installed Kubuntu on my laptop (Dell XPS). I was configuring Power Devil, and made the mistake of deleting one of the profiles. Now Power Devil won't work at all. I get the error message
System Settings -> Advanced -> Power Management gives an error message which unfortunately I can't copy/paste. But it begins
"The configuration module can't be started ...." then
"Power Devil seems not to be started. Either you have its service turned off or there is a problem in D-Bus."

Any suggestions for cuing this? It's annoying not having this facility.

Thanks, James

Please remove powerdevilprofilesrc from $(kde4-config --localprefix)/share/config while outside of KDE.

Thanks. I've done that (a quick search came up with ctrl-alt-f1 to quit X and hence kde).

So after rebooting, the file you said to delete (which was in ~/.kde/share/config) is no longer there. But the problem persists, with the same error message. So what do I do next?

Thanks,
James

Were you fully logged out of KDE when you switched to the Virtual Terminal ( Ctrl + Alt + F1 )?

Try removing $(kde4-config --localprefix)/share/config/powerdevilrc also...

Thanks bcooksley - I followed your suggestions and PowerDevil now works!

I didn't realize that ctrl-alt-f1 didn't quit kde. But you're right - it doesn't, so how does one quit kde?

(Though your suggestions worked without quitting kde.)

Thanks again

James

Logout - or Ctrl-Alt-Backspace, though technically, this stops X, but it also takes you back to the login screen, so from a user point of view, it's the same.

I guess you meant ctrl-alt-del (ctrl-alt-backspace has no effect - at least on my system: kubuntu with kde 4.3)

But logging out does not quit kde - it just gives you the login screen which is in kde. So how does one actually quit kde? I guess one way is to do ctrl-alt-f1 and then kill kdeinit. But is there a better way?

Ctrl + Alt + Backspace is a shortcut provided by the X server which causes it to self-terminate. Many distributions have disabled it unfortunately.

Logging out in this case is all that is needed, since as long as KDE isn't running as your user, the task can be performed. Note that you should never kill kdeinit4 as that will terminate your session immediately. Same for KSMServer.

OK. Thanks for all that.
And problem solved.
James
