I must be dumb or something, because I can't get lancelot to work right. I get a pretty little plasma icon, but that's it. For several weeks now I thought lancelot just wasn't ready yet. I would click, double-click, alt-click and nothing would happen. Soft click does nothing, hard forceful click with much screaming and shouting does nothing. It's just an icon doing nothing.

Then I discover a few minutes ago, that if I run "lancelot" from the commandline *first*, then use the applet, it works. Huh? Is this a bug, or am I just not groking the utter coolness of lancelot? Thanks.

Works for me absolutely fine upon mere adding to the panel. Seems like a distro specific problem to me.

I built from svn. So apparently there's extra configuration involved besides just building, installing and adding it to the desktop. I guess I need to add "lancelot" command to a startup script. I hate guessing, is there documentation anywhere?

Cant seem to find much here: http://lancelot.fomentgroup.org/docs

Plus, I didn't compile but I use the one shipped with kubuntu repositories, so I don't have much idea. Though adding it to the ~/.kde/Autostart should work out good.

Here is a list of all the files I can find that appear related to lancelot on my system. I installed it from an opensuse rpm, but maybe it can give you some hints:

Lancelot is a Plasma applet, so therefore has been moved to the Plasma forum

Hi, that's what the FAQ section at the site is for
http://lancelot.fomentgroup.org/faq#menu-doesnt-open

The main problem is that D-Bus can search only in one directory for service files, and when you install KDE from SVN into some other prefix than /usr (or, to be more precise, in different prefix than that of D-Bus), it installs the service file in the prefix you have specified (which is the right thing to do), but then your system's D-Bus can not find it.

So, for a quick solution, do:

Code: Select all

# cp `kde4-config --prefix`/share/dbus-1/services/*lancelot* /usr/share/dbus-1/services/

Since this is very irritating, I'm thinking of starting L manually (on applet initialization) instead of using D-Bus services, but, then, what is the point of D-Bus service mechanism...

Thanks, I'll give that a shot. I suspect it might even fix a few problems I've been seeing with other components.

If it worked, just put a [SOLVED] tag in the topic title. Cheerio!
