OBS Virtual Camera won't start (v4l2loopback-dkms)


New Member
I'm running on Wayland.

After installing obs-studio and v4l2loopback-dkms via pacman -S obs-studio v4l2loopback-dkms, I open obs and "Start Virtual Camera" does appear, however nothing happens when clicked.

In terminal, I see the following:
==== AUTHENTICATING FOR org.freedesktop.policykit.exec ====
Authentication is needed to run `/usr/bin/modprobe' as the super user
Authenticating as: jivvy
polkit-agent-helper-1: error response to PolicyKit daemon: GDBus.Error:org.freedesktop.PolicyKit1.Error.Failed: No session for cookie
Error executing command as another user: Not authorized

This incident has been reported.
I am definitely entering my password correctly.

If any more information is needed, I can provide.

I found this reference on another thread in this forum -->
The issue was because v4l2loopback is unsigned and secure boot was turned on.
Solved by disabling secure boot on ubuntu 20.04.
I am running Zorin 16 and was having the same issue with the Virtual Camera.

Based on the advice, I entered BIOS and disable secure boot. Restarted the PC and ran OBS again.

The Virtual Camera works like a charm now!
