Ubuntu – VLC crashes when opening any file, Ubuntu 20.04

20.04crashsegmentation faultvlc

My VLC player crashes every time I'm trying to open any video file. Removing/purging vlc, and reinstalling it does not change anything.

I recently upgraded my distro to 20.04 from 19.10. I never had this problem on any other operating system before. I also tried to reinstall the whole operating system from scratch (because I also had some other minor issues). Then VLC worked fine on a fresh installation, but at some point it started to crash again, and now again it always crashes.

Running vlc from terminal gives the following output when I try opening a file.

[00005586d4e98290] main libvlc: Running vlc with the default interface. Use 'cvlc' to use vlc without interface.

And this is the log about that shown in the gnome-logs:

There's a bug report about that here.In fact VLC is not to blame.There's a bug in the intel driver iris_dri which is a linux Direct Rendering Infrastructure driver for the intel IRIS graphics cards.

Whenever a program tries to bypass the X server and renders directly using OpenGL on the underlying GPU , it has to use that driver indirectly.And a bug causes segmentation fault when someone issues OpenGL calls.

As suggested in the bug report , you have to use the intel driver i965 instead.In order to do that you have to define the environment variable


So if you want to open VLC in the terminal , you have to add that line to your ~/.bashrc file or if you want to open it from the application menu or by clicking on a media file , you have to tamper the line beginning with Exec= in the .desktop file /usr/share/applications/vlc.desktop :

Exec=env MESA_LOADER_DRIVER_OVERRIDE=i965 /usr/bin/vlc --started-from-file %U

And if you want to set that globally for all of your applications , add this line to the file /etc/environment:
