How To Fix primusrun: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu primusrun is provided by primus package.

primus is:

Primus is a shared library that provides OpenGL and GLX APIs and implements low-overhead local-only client-side OpenGL offloading via GLX forking, similar to VirtualGL. It intercepts GLX calls and redirects GL rendering to a secondary X display, presumably driven by a faster GPU. On swapping buffers, rendered contents are read back using a PBO and copied onto the drawable it was supposed to be rendered on in the first place.

Primus is currently intended to be used alongside Bumblebee and provides a drop-in replacement for optirun (i.e. “primusrun”).

To fix this problem, we can install more using the command below.

sudo apt-get -y install primus

This command might take some time to finish depending on your machine internet connection.

You can also use apt command to install primus.

sudo apt -y install primus

Or if you have aptitude installed you can use the following command.

sudo aptitude install primus
