                          I have a Thinkpad X1 Tablet (gen 2) with a front and back integrated camera running Ubuntu 19:10.  The cameras appear to be detected:

When I start cheese I have 4 cameras labeled "ipu3-imgu".  When I run guvcview I have 10 devices labeled "ipu3-imgu" which the system puts at /dev/video0-9  and four devices labeled "Intel IPU3 CIO2" which are /dev/video10-13.

 

But none of these work.  Does anyone have a laptop with this kind of camera running Linux?

Does anyone know of a resource on debugging this kind of camera in Linux?
