I have a DELL Lattitude 7285 (2-in-1, detachable) laptop, the only problem I am experiencing is that the cameras (inner and outer) do not work. According to hardware specification there shouls be:
Inner:
- IR camera (Realtek)
- 2 regular cameras
- light sensor
Outer:
- camera with autofocus
In /dev there are listed video devices:
/dev/video0
/dev/video1
/dev/video10
/dev/video11
/dev/video12
/dev/video13
/dev/video2
/dev/video3
/dev/video4
/dev/video5
/dev/video6
/dev/video7
/dev/video8
/dev/video9
I tried to identify these using V4L2 (output bellow) since lsusb nor lspci had any information regarding cameras (could not find anything like cam, Realtek or IPU3).
I tried to get image using V4L2 Test Utility (with driver IPU3-CIO2).
I found mention of Libcamer according to their documentation is seems not to solve my problem, that is want to use cameras for usual purposes such as videoconferencing.
Thank you for any suggestions on how to get cameras working.
Notes:
Cameras work flawless using Windows 10
GNOME detects light conditions using lighsensor without problem
