Camera access permission

Ask Fedora
1

Sorry if the question is basic, it’s my first time using linux. I’m on Fedora 41. Built-in camera app doesn’t work because it doesn’t have access. I looked it up in the settings and on the internet. Looks like all of the permissions are for the user there. The camera access in the settings is turned on, I also added my user to video group through termial and run

sudo modprobe uvcvideo

just in case. Please give advice on how to give my camera and other apps permission of camera access

I had this issue.

opened settings → privacy & security then turned off allow permission for apps. restarted the camera app.

I have the same issue, also on Fedora 41. The camera app just shows a black picture saying “Missing Camera Permission. Allow camera usage in Settings”, but the Privacy and Security settings are already set to “Allow permitted apps to use cameras”. Did you find a solution?

I think that the “Allow permitted apps to use cameras” label should be rewritten to read, “allow only permitted apps to use cameras.” As crazyram pointed out, above, turning the setting off permits the Camera app to work.

I should have said, but I did actually try that. When I set it to off the text “Missing camera permission…” disappears, but the picture is still just black with the barred, white camera symbol.

The setting seems flipped, it works for me like this:

gsettings set org.gnome.desktop.privacy disable-camera true

The label means what it says. However, unsandboxed apps can do whatever they want (as Settings warns below ‘Permitted Apps’).

What may be happening is that going through the Camera portal isn’t working, and locking down the Camera portal entirely makes the app use Pipewire directly instead.

There have been some issues with certain portals not working reliably for unsandboxed apps. The Flatpak version should work properly.

I assume that you’ve confirmed there is no shutter over your camera?

12

Yes. But I realise that now it is probably a camera malfunction or driver issue. The text “missing permission” does go away when I set disable-camera to true/turn off “allow permitted apps to use cameras”. I guess that means there is no longer a permission issue and my problem does not belong here. But the awkward wording of these parameters didn’t help me realise that…

Thanks, it helps!
