Troubleshooting

libnvidia-fbc.so.1: cannot open shared object file: No such file or directory

The possibility of this error arising exists if you possess an NVIDIA graphics card, as the package does not include the NVIDIA X11 libraries in its wrapper by default.

1. Make sure your drivers are installed.
2. Install the missing the NVENC patch for your card. nvidia-patch is a great overlay which you can use
3. Override the package build inputs and add the library to the wrapper.
