Hi,

I recently bought an HP Dragonfly 13.5 inch G4 Notebook PC. In order to install ubuntu, I had to disable secure boot in bios setting. The integrated camera works perfectly fine in Windows but it doesn't work in ubuntu 22.04. Also installed cheese and it says no device found. Any suggestions what can be the problem? Can it some bios settings that I have messed with? Here are some logs

If this is a new machine, check the manual, there may be a key combination [or separate switch] to enable the camera [this is a security feature on some machines to stop remote activation]
 
Yes, the laptop has a webcam shutter key. I already experimented with that but it is on and turning it on and off doesn't seem to help
 
Can it some bios settings that I have messed with?
As webcams are classed as USB devices [on the USB Bus] then only if you have changed anything in the USB Bios/UEFI settings.

this works on some [not all] HP Lappies

open Bios Setup (F12)
System Configuration > Miscellaneous Devices > Enable Camera
