40.5 Kadesh Kernels


Kadesh is a Dell Latitude 7440 Desktop. See Section 40.2 for details.

Here we review updating to the latest released kernel. These are not necessarily yet supported for Ubuntu though they do come from a Ubuntu repository: https://kernel.ubuntu.com/mainline/. The aim has been to get the camera working through updated kernel support.

The mainline package provides an interactive GUI to manage installed kernels.

The current kernel was 6.5.0-14.14, an official Ubuntu kernel. Through mainline select 6.7 and then Install.
