I was using VLC in Ubuntu 12.10 for some time. Today the application failed to open. The application had given me problems earlier too, today I finally resolved it.
If your VLC behaves erratically, then enter this command in your terminal:
lsb_release -a; uname -a; apt-cache policy vlc
Now if the output of the following is something like this:
No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 12.10 Release: 12.10 Codename: quantal Linux CrystalBox 3.5.0-19-generic #30-Ubuntu SMP Tue Nov 13 17:49:53 UTC 2012 i686 i686 i686 GNU/Linux vlc: Installed: 2.0.4-0ubuntu1 Candidate: 2.0.4-0ubuntu1 Version table: *** 2.0.4-0ubuntu1 0 500 http://archive.ubuntu.com/ubuntu/ quantal/universe i386 Packages 100 /var/lib/dpkg/status
Then enter the following command in terminal:
mv ~/.config/vlc ~/.config/vlc_old
This should solve the problem!
