I dont get the video / screenshare portal on Firefox and Signal Desktop (Electron). They both worked normally before.

Comment 1 Henning 2023-12-11 16:30:46 UTC

Meanwhile Audio access works.

Comment 2 Nate Graham 2023-12-11 20:02:52 UTC

What happens instead?

How exactly are you triggering these portals?

Can you run `journalctl -f`, reproduce the problem again and paste any errors or warnings that appear when you do so?

Comment 3 Henning 2023-12-11 23:40:38 UTC

It doesnt do anything. Signal Desktop would open the portal interface, you would select the screen and tadaa signal shows your screen. Same on BBB, it just says "no camera found" etc, as the portal is not opening

Weird, I cannot reproduce this after a reboot.

Will set as worksforme until it happens again
