Ubuntu – VLC 2.2.6 doesn’t open

16.04software installationvlc

I am using Ubuntu 16.04 LTS and recently I upgraded my VLC from 2.2.2 to 2.2.6. But after that the GUI of VLC doesn't open. It just flashes in the taskbar and closes. There is no background task running as VLC. I tried reinstalling VLC but nothing happens. I tried launchin by command line which works good.

You signed up for Ask Ubuntu today and this is your first question on Ask Ubuntu, so maybe you don't know that VLC 2.26 is an Ubuntu snap package. In order to install it open the terminal and type:

sudo apt install snapd  
sudo snap install vlc

Delete the VLC profile

Deleting the profile folder of VLC makes it work as when you first installed it.

Using terminal

Open a terminal (press Ctrl+Alt+t)
Run rm -rf .config/vlc/

Using GUI

Go to Home folder
Show hidden files (press Ctrl+h)
Open the folder .config
Right click on vlc folder and delete
Restart VLC and see how it works.

Ubuntu – Vlc cannot play mkv and mp4 formats

I ran into this issue because VLC was attempting to use VDAPU for video decoding, and it was causing a segmentation fault. Presumably this is actually a bug in the open source Radeon drivers, but I was able to work around this by simply disabling hardware video decoding. The setting is kind of buried, just open VLC then go to Tools->Preferences->Input/Codecs and set Hardware-accelerated decoding to Disable.

In case this didn't solve your particular problem, I was able to figure out that it was a problem with VDAPU by executing the following steps:

ulimit -c unlimited to get Ubuntu to actually create a core dump
vlc from the same terminal
Wait for segfault
gdb `which vlc`
core core Load the core file which is actually called core

bt This gave me the following ouput:

The entry at #8 showed me that the problem was in the Radeon drivers.
