Appeared to solve the problem with the integrated webcam (Azurewave 13d3:56ff).
Unfortunately, after a few days of use the issue returned. The camera sometimes works after reboot, but often it opens once (e.g. in Chrome/Meet) and then immediately closes, or /dev/video0 disappears entirely. Cheese and GNOME Camera also show "could not play camera stream" and close by themselves. Additional observations: dmesg shows repeated disconnect/reconnect cycles with error -71. Only one application at a time can use the device; if Chrome is holding /dev/video0, Firefox or Cheese cannot access it. The GRUB quirk improved stability but did not completely solve the problem. Temporary workaround: Manually resetting power management and reloading uvcvideo makes the device reappear without reboot: echo on | sudo tee /sys/bus/usb/devices/1-6/power/control sudo modprobe -r uvcvideo && sudo modprobe uvcvideo echo '1-6' | sudo tee /sys/bus/usb/drivers/usb/unbind echo '1-6' | sudo tee /sys/bus/usb/drivers/usb/bind So it seems this is a uvcvideo/USB power management regression with device 13d3:56ff. The GRUB quirk is not enough for a permanent fix. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2118786 Title: Webcam integrada (13d3:56ff) some intermitentemente em Ubuntu 24.04 + NVIDIA driver-535 (X11) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-hwe-6.14/+bug/2118786/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
