Running VLC without KDE

MarcoB

Hello,

Every time I try to start and open a file in VLC, it locks up and generates some errors

Code: 
VLC media player 1.1.5 The Luggage (revision exported)
[0x285290fc] main libvlc: Found old config file at /home/marco/.vlc/vlcrc. VLC will now use /home/marco/.config/vlc/vlcrc.

kbuildsycoca4(1281)/kdecore (services) KServicePrivate::init: The desktop entry file  "/usr/local/kde4/share/applications/kde4/koffice.desktop"  
has Type= "Application"  but no Exec line

When running VLC for the first time, the "open file" dialog causes VLC to run a bunch of "kdeinit4" processes, and it locks up. After killing vlc and restarting it, the lockup doesn't happen.

My point is that I want to use VLC, without a lot of kdeinit4 processes running, and without having to start VLC twice every time I want to use it. Afaik KDE isn't a dependency of VLC so the kdeinit4 processes shouldn't be needed. Is there a solution for using qt4 apps without KDE?

Thanks,

Marco
 
kdeinit4 is just a process launcher that is used to execute common KDE programs. kdeinit4 will be launched when you try other kde programs as well, for example, kile, amarok etc. You may not have kde desktop installed in any way, but using these programs in another wm or desktop will launch kdeinit4.

If you have other qt4 apps installed, try launching them and see if you get the same error. Also, for vlc, try this on the command line, and post the results.

Code: 
vlc -vvv --reset-plugins-cache

I have KDE installed but I don't use it now (using fluxbox at the moment). Kdeinit4 isn't launched when vlc is started, but only when I try to open a file, and then it locks up.

I thought vlc was a qt4 app and not a kde app. Like e.g. LyX that uses qt4 but doesn't start kde. So I don't see why vlc needs kde. Also, I have run vlc in the past whithout needing kde.

Also, for vlc, try this on the command line, and post the results.

Code: 
vlc -vvv --reset-plugins-cache

This is what I get when starting vlc whith the options above, and opening a file:

I don't use vlc. Yes there are a lot of qt4 apps that don't rely on kde. I was mistaken with vlc. Sorry. I will look into the command output and see if there is something amiss.
 
So the problem doesn't seem to be on the vlc side. It appears that kdeinit4 is the problem. When you start vlc for the first time, kdeinit4 gets launched but for some reason messes up. But launching vlc again doesn't seem to cause the problem. Just to double check, may be you can start kdeinit4 first, by issuing the command in a terminal. And then launch vlc. Also try to see what happens if you launch some kde apps, like konqueror or kate etc., just to be sure if the kdeinit4 launch is the culprit.

Could be that kde4 installation had been faulty. Did you do a clean install or did you upgrade? More after going through the messages.
 
I've installed kde for some time and every once in a while I try it (same for gnome), but usually I return to fluxbox which is a lot faster ;) Kde gets upgraded when I "portupgrade -a" (weekly).

I'll try other kde apps and see what happens.
 
Tried with konqueror (with starting kdeinit4 first and konqueror directly) and then there are no problems (besides from the fact that there are like 10 instances of kdeinit4 started). Starting vlc after starting kdeinit4 gives no problems either. Question remains why vlc wants to start kdeinit4 and how I can start vlc without it.
