Need help to determine if Kaisen is compatible with my computer

I wanna use Kaisen in my work every day.
For this moment, it very difficult because I have some issue probably with driver.

For exemple, I need to switch to sddm in place of lightdm because my screen blinking
I have an issue with my thunderbolt 4 port. I have a dell dock , charging and usb work but HDMI, VGA, Mini DP doesn’t work.

It’s possible to find all of hardware components and show if firmware was installed ?

Maybe kernel 6.0 help me with recent computer.

I have a Dell Inspiron 16 Plus (cn76107) with NVIDIA graphic card and i7-11800H


For your problem with lightdm, you can use the sudo dpkg-reconfigure sddm to set sddm by default (lightdm is set by default only when is the first installation of the kaisen-kde package).

For drivers, the linux-firmware-* packages with Linux 5.19 are the most recent drivers and hardware support possible today. Linux 6.0 is currently in beta, I’ll not take the risk to deploy it in production.

May be, for your Dell dock, a driver for Linux can be probably found on the Dell website.

OK, I think this dock is too older …

You don’t have these firmwares available to download on a Dell website?

no and I try with another dock.
This is a usb-c to hdmi + usb very simple and hdmi doesn’t work

Thunderbolt 4 was greatly integretad with 5.19 kernel ?

Yes, the thunderbolt works.

I using the thunderbold all days for example my USB keys.

On an other distrib or Windows, your dock works?

Yes, on windows it’s work with 2 external screen
Other dock wth HDMi doesn’t work too

What are the reference of your docks?

I have seen on the Dell website, no driver is available for Linux.

This problem is present in other distro for example Manjaro, Ubuntu or PopOS?

On ubuntu and MX same problem

What is the reference of this dock?

Okay, I think that of the support of this hardware as not been done by Linux developers (and I’m not a kernel developer, I can’t develop myself this driver).

May be trying to update firmware from a Windows (only the Windows .exe is provide by Dell) and drivers and retry to connect your dock.

Already doing :confused:

I saw somwhere need to install displaylink driver

Okay, I don’t think I can do anything for you, I’m sorry.
If this hardware isn’t supported by Linux and no firmware is provided, I can’t help you… :frowning:

Personnaly, I not using Dell hardware, in particular for these reasons.
I prefer using Lenovo hardware (PC and docks), I have never had a problem with Lenovo on many Linux distro (Debian stable, Manjaro, Ubuntu).

Hello @Iwios,

Can I close this ticket?
