Fwd: AX500 support quirks

[Patricio Ferraggi Ares]

Hi,

My name is Patricio, I am a fellow software developer and user of the
Dell XPS 9310 (AX500 version). First of all, I wanted to thank you for
all your hard work bringing support for this model, thanks to you, I
have been able to use my laptop with Linux almost since I got it.

This is not a bug report in any way, I just would like to gain some
knowledge on the subject and you might be the perfect person for my
questions.

I noticed that although all distros use the Linux kernel, support for
this hardware is not the same across all Linux distros. To be more
specific, Ubuntu-based distros have had working wifi and Bluetooth for
almost a year now, although there are some problems like resuming from
deep sleep,  both wifi and Bluetooth work right away on installation,
at the moment I am using Pop OS with Linux kernel 5.15.5 as my main
driver. On the other hand, arch-based distros dont' have working BT,
as you can see here and here. The wifi is working but Bluetooth
sometimes doesn't turn on and when it does it cannot properly connect
to devices. This happens across multiple arch-based distros and kernel
versions, even if I try kernel versions that work fine in PopOS, they
don't in Arch.

So finally, my questions:

Why is there this inconsistency of support between distros when
theoretically, they are all Linux?
Why is it that if Arch is always updated, in this particular case
their hardware support is lacking compared to ubuntu?
And finally, do you have a working configuration with wifi and
Bluetooth? if that is the case could you tell me your distro, kernel,
firmware, system firmware versions?

Sorry for the long email, I wanted to be as explicit as possible.
Have a great day.

Kind regards,
Patricio Ferraggi Ares
