40.4 Kadesh Issues


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

Gnome Crash

With Ubuntu 23.10 there was an issue (also exhibited on johna after an upgrade) causing the server to display a blank screen with the only option to Log Out. It appeared related to displaying video or playing audio from totem or from youtube. Also reliably when hit Alt-F2 then r (reset). Disabling the Media Controls extension fixed the video/audio issue but not the Gnome Shell reset issue.

Internal Camera

This laptop has an internal camera that does not work out of the box. Asking Dell support: I am running Ubuntu 23.10 on Latitude 7440. The in built camera is not detected. Can you advise how to get the camera working. Thanks.

They have not been very helpful with the not supported repsonse.

sudo journalctl  -b  0 | grep -i camera

This should identify the integrated camera but for this laptop there is nothing.

Looks like we are out of luck for now with the camera.

A potential solution is https://bbs.archlinux.org/viewtopic.php?id=287119 and the estimate for support is 2024/2025 sometime! For Ubuntu perhaps try https://askubuntu.com/questions/1473289/integrated-camera-not-working-on-dell-latitude-7440-and-7340-ubuntu-22-04

See 40.5 for installing latest but not yet formally released for Ubuntu kernels.

Keyboard Backlight

The laptop was ordered with a back lit keyboard but not delivered with one. The back light is important as it is extremely useful in even slight darker environments, as working in the evening. It took Dell over 6 weeks to rectify which involved simply replacing the keyboard with one supporting back lighting.


Wayland works but X2Go could not display. Revert to Ubuntu on X11. Perhaps Exec=env QT_QPA_PLATFORM=xcb x2goclient in ~/.local/share/applications/X2GoAgent.desktop (to be tested).
