Hey, My monitor, a Dell S2340T, has a builtin webcam. There's no camera button for it, though that wasn't a problem up until recently. This is a trimmed output of evtest: /dev/input/event14: DELL S2340T Webcam: DELL S2340T /dev/input/event15: DELL S2340T Webcam: DELL S2340T /dev/input/event16: DELL S2340T Webcam: DELL S2340T <snip> /dev/input/event31: DELL S2340T Webcam: DELL S2340T /dev/input/event256: DELL S2340T Webcam: DELL S2340T <snip> /dev/input/event365: DELL S2340T Webcam: DELL S2340T /dev/input/event366: DELL S2340T Webcam: DELL S2340T More than a hundred device nodes registered. Only one of them shows up in the output of "udevadm info --export-db". Current tip of my tree is commit 37cb8e1f8e10. Did I miss a fix going in for this problem? Do I need to try and bisect it? Cheers
