I am using gnome and my laptop is Redmibook with built in webcam. It has i5-11th gen cpu.
I am running this 6.7.2-arch1-1 kernel
The webcam sometimes come-up as a listed device and sometimes doesnot show-up at all.
Also when the camera is detected...it gets disconnected arbitarily...
Some other informations...
v4l2-ctl --list-devices
Cannot open device /dev/video0, exiting.sudo dmesg | grep -i -e camera -e uvcvideo -e "usb 1-12"
