I'm no linux expert but I'm not exactly a novice either. I have established what triggers the problem, just don't know how to fix it. When I try to test timelapse webcamd is disabled fails to start and even with timelapse disabled I cannot get webcamd to run anymore.
Hardware
Raspberry Pi 3B+
Arducam B0033R
Waveshare 3.5" LCD touch display
8gb SD card
Process
Clean Octoprint image - 2019-09-26-octopi-buster-lite-0.17.0
raspi-config enable camera,ssh,configure wifi
Reboot
Open Octoprint and enter initial configuration - Do NOT enable authenticated access or you'll be prompted for Octopi Login before booting directly to desktop (learned that one already)
select Control option in Octoprint - webcam is displayed
sudo /home/pi/scripts/install-desktop
sudo raspi-config - boot options - desktop GUI - boot to GUI logged in as PI user
Reboot
Boots to desktop no problem
Octopi - Control - Webcam still working
git clone https://github.com/waveshare/LCD-show.git
LCD-show 0
Reboot
Seemless boot to desktop GUI - 480x320 resolution - touch display working
Open OctoPrint - Control Tab - Camera working
apt-get update && apt-get upgrade
Reboot
Seemless boot to desktop GUI - 480x320 resolution - touch display working
Open OctoPrint - Control Tab - Camera working
OctoPrint - Timelapse Tab - Camera disabled - webcamd service fails logs show errors
Please help! Thank you.
Camera model
Arducam B0033R
What is the problem?
I can view the CAM via the control tab. As soon as I click on the Timelapse tab webcamd fails and the camera is no longer accessible.
What did you already try to solve it?
Reboot = failed
sudo systemctl restart webcamd = failed
read hundreds of unrelated posts = no luck
Re-image my sd card with Octopi and start over = confirmed timelapse disables webcamd permanently
