I have a Lenovo Legion laptop with integrated camera. There is Ubuntu 24.04 installed. After some updates (I am on livepatch) the camera did not show any image. The typical "Camera not found" issue (before it was ok), but I overcame it following some helpfull links, but the camera did not show an image. I tried 2 days long different approaches, driver, applocker, cheese, pipewire, could not solve the problem. Finally installed a fresh Ubuntu 24.04, all my applications etc. Today, after a week of good working, I did another update, rebooted and I had the same error again - no camera image. I hesitate to start again with installing additional software guvcview, cheese etc. to analyse again, instead stay as near as possible to the main stream distribution and keep fingers crossed.
Do you recognize this problem? Thank you for your time.
