Logitech C920
What is the problem?
When I cold boot my Raspberry Pi 4, my webcam works fine. Even with custom settings.
I have installed the Desktop environment to use the pi for other lightweight tasks aswell.
As soon as I login to the desktop environment and refresh/wait the control panel on octoprint, the webcam disables and is stuck on loading.
EDIT: This doesnt seem to be just with login into the desktop environment, after a couple if minutes the webcam just stops working.
What did you already try to solve it?
To be completely honest I have no idea where to start here, I've tried searching if the desktop environment pulls the cam but I cannot find anything.
I also tried increasing the GPU memory by double on the Pi, but that doesn't seem to work either.
Logs (/var/log/webcamd.log, syslog, dmesg, ... no logs, no support)
Cant find webcamd.log for some reason, it doesnt exist.
