40.5 Kadesh Kernels
20240514
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.

This did not fix my missing camera! But I had a new kernel!
On 20240514 I updated to the latest kernel:
But it complained about not being able to install libelf1t64 (>=
0.144) and libssl3t64 (>= 3.0.0) required by
linux-headers-6.9.0-060900-generic. A reboot failed initially. Going
back to 6.7 also failed (stopped at the boot screen with the logo and
all dots filled, making no progress). Booted into 6.5 okay and did a
sudo apt --fix-broken install
and that fixed the bad state of the
pacakges. A boot back into 6.9 was okay. Though I lost my USB
mouse/keyboard a couple of times.
Currently stay with 6.9 and a working external USB camera.
Try 6.11 on Ubuntu 24.04 through Mainline
This supports ipu6:

On reboot plugged into the dock the laptop starts up to the Ubuntu login screen but the mouse/keyboard are not responsive. Reboot with the dock unplugged and the laptop mouse/keyboard are okay and can see the ipu6 libs loaded but no camera found by cheese. Plug in the dock and it all freezes permanently. Test moving to Ubuntu 24.10 which comes with kernel 6.11 as native. Problem remains.
