Can not run OBS after installing Nvidia drivers on Debian

[rpagliuca]

What I tried:

snap run obs-studio

What happened:

Command failed with the following output: /snap/obs-studio/1090/usr/bin/obs: symbol lookup error: /snap/obs-studio/1090/usr/lib/x86_64-linux-gnu/libGL.so.1: undefined symbol: _glapi_tls_Current

Exit code

$ echo $?
127

What should have happened:

I expected to see a window of obs-studio visible (and functional) on my desktop environment.

It was working just fine 2 days ago

The command snap run obs-studio has been working fine for several months until yesterday, when I installed nvidia-driver on my system.

$ sudo apt-get install nvidia-driver

Some more evidence: I've just removed the nvidia drivers and obs-studio started working again.

sudo apt-get remove nvidia-*

Well, that does not fix the root cause, and I'd really like to keep using the nvidia drivers if possible :-)

[rpagliuca]

I've crafted a temporary fix based on https://forum.snapcraft.io/t/nvidia-libraries-not-accessible-inside-snaps/15227 and https://askubuntu.com/a/1036611/113640.

SOURCE="/usr/lib/x86_64-linux-gnu"
DEST="/snap/obs-studio/1090/usr/lib/x86_64-linux-gnu/"
sudo mount --bind $SOURCE/libGL.so.1 $DEST/libGL.so.1
sudo mount --bind $SOURCE/libEGL.so.1 $DEST/libEGL.so.1.0.0
sudo mount --bind $SOURCE/libGLX.so.0 $DEST/libGLX.so.0
sudo mount --bind $SOURCE/nvidia/current/libGLX_nvidia.so.390.138 $DEST/libGLX_mesa.so.0

Due to /snap/obs-studio/ being read only, instead of simply copying, I had to resort to mounting the correct libraries on top of it.

If anybody in the future try to reuse those commands, you should check for the correct SOURCE and DEST in your specific setup, and perhaps the exact name of the files.

Looks like this is a bug regarding the interaction between snapd and the way nvidia-driver provides NVIDIA userspace in Debian.

@rpagliuca's answer helped me fix my problem, though the error message was different, a pop-up with the text

Failed to initialize video. Your GPU may not be supported, or your graphics drivers may need to be updated.

you should check for the correct SOURCE and DEST in your specific setup, and perhaps the exact name of the files

I found that in DEST you can use current instead of the version number, and link libGLX_nvidia.so.0 instead of the versioned file library. That should remove the need to adapt to new versions.

A full wrapper script:

SOURCE="/usr/lib/x86_64-linux-gnu"
DEST="/snap/obs-studio/current/usr/lib/x86_64-linux-gnu"

sudo mount --bind $SOURCE/libGL.so.1 $DEST/libGL.so.1
sudo mount --bind $SOURCE/libEGL.so.1 $DEST/libEGL.so.1
sudo mount --bind $SOURCE/libGLX.so.0 $DEST/libGLX.so.0
sudo mount --bind $SOURCE/nvidia/current/libGLX_nvidia.so.0 $DEST/libGLX_mesa.so.0

snap run obs-studio

sudo umount $DEST/libGL.so.1
sudo umount $DEST/libEGL.so.1
sudo umount $DEST/libGLX.so.0
sudo umount $DEST/libGLX_mesa.so.0

For anyone encountering this issue, Debian users have a couple of options for getting a current OBS Studio version:

• OBS Studio Container - comes with the same plugins as this snap
• OBS Studio Flatpak - vanilla upstream release
