Intel 13700k iGPU not recognised

[Erik Giorgis]

Hi

I installed guix on a new system, and would like to use Hyprland with it. I 
already have Hyprland working on an older laptop. 
However, on this new system I get an error that the iGPU is not supported by 
mesa. 

A quick lspci:

VGA compatible controller: Intel Corporation Device a780

Also a lot of other devices are just marked as "Intel corporation device", and 
not recognized (it seems).
I tried booting another OS, and the iGPU is correctly recognized as a UHD 770.

I'm having this problem while on kernel 6.2.7, haven't tried other versions.

Thank you a lot in advance,
Erik
