(0008101) joker (reporter) 2012-05-30 10:36	I just found out that I can start it when I run it as root kdesu kdenlive I have to add that I installed it not system wide. Any Ideas?

Maybe you have a video capture device (webcam?) that is causing problems. In this case, as a temporary workaround you could try to blacklist the kernel module enabling the device ?

(0008685) sunabiz3d (reporter) 2012-12-02 20:24 edited on: 2012-12-02 20:24	It's frustrating, because kdenlive is the BEST open source video editor. I have two v4l2 devices, an old saa7134, an Genius FaceCam 1020 and also use a virtual device, v4l2loopback. I removed the v4l2loopback module from /etc/modules: # /etc/modules: kernel modules to load at boot time. # # This file contains the names of kernel modules that should be loaded # at boot time, one per line. Lines beginning with "#" are ignored. lp rtc #v4l2loopback video_nr=1 I blacklist the saa7134 & saa7134_alsa modules in /etc/modprobe.d/: blacklist saa7134 blacklist saa7134_alsa #options saa7134 card=65 tuner=4 video_nr=0 And I unplugged my FaceCam from the USB port, but, the situation is the same: me@ubuntu:~$ ls /dev/video* ls: cannot access /dev/video*: No such file or directory me@ubuntu:~$ gdb kdenlive GNU gdb (Ubuntu/Linaro 7.4-2012.04-0ubuntu2) 7.4-2012.04 Copyright (C) 2012 Free Software Foundation, Inc.

(0008686) sunabiz3d (reporter) 2012-12-02 23:42	Frustrated, I enabled all my video devices again. After seeing that the user vayu in http://www.kdenlive.org/forum/kdenlive-wont-start [^] reported to be using Kubuntu, I logged into Cinnamon, GNOME, Enlightenment, WindowMaker and Unity to verify that kdenlive launched correctly in all of them. However, with Razor-Qt and KDE kdenlive did not pass the wizard. After configuring kdenlive on another desk, logged back into KDE, and kdenlive worked unstable. I repeated my tests using the Guest account, and kdenlive worked on all desktops. So I concluded that it was my KDE desktop customization that is causing problems. One component I compile on my own, as it is not available in Ubuntu, is oxygen-transparent. Changed the application appearance in KDE to Oxygen and voila!, kdenlive worked perfectly and only closes when I get back to Oxygen-transparent. Perhaps this will serve as a temporary workaround to the other people who have this problem. The problem seems to be oxygen-transparent in my opinion, not kdenlive. Keep up the great work. :D

(0008687) nexces (reporter) 2012-12-03 06:54	Confirmed. Switching back to oxygen (not transparent) fixed the issue.
