DELL 7440 camera still not working ubuntu 22.04

The above mentioned post reads

The camera does not works with oem-somerville-lapras-meta
The camera works with oem-fix-misc-cnl-i915-disable-psr

Try switching the 4th additional driver from

  • ‘Using hardware support for Dell Latitude (…)’ to
  • ‘Using Disable i915 PSR capability (…)’

[Edit]
Just saw that first additional driver is set to ‘Using HAL library for MIPI camera (…)’. The label sounds like you should activate that, too.
