After further investigation, I realized the issue was not related to the NVIDIA driver or kernel version itself.
The integrated webcam (Azurewave, 13d3:56ff) was being detected in dmesg but /dev/video0 was not created, producing errors like: usb usb1-port6: Cannot enable. Maybe the USB cable is bad? usb usb1-port6: device not accepting address, error -71 Because of this, Cheese/Camera showed "camera not found" or "could not play camera stream", while browsers sometimes managed to use the camera once, but it disappeared afterward. The fix was to add the following USB quirk in GRUB: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash usbcore.quirks=13d3:56ff:u" After reboot, /dev/video0 and /dev/video1 are created correctly and the camera now works consistently across Cheese, GNOME Camera and browsers. So this seems to be a uvcvideo/USB quirk issue specific to device 13d3:56ff, rather than an NVIDIA or general kernel regression. -- 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
