i'm not, i'm using zorin, it's the first out of like 5 options i've tried that boots into a working X due to its suitable amdgpu drivers and kernel version:
Linux iox 6.2.0-39-generic #40~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Thu Nov 16 10:53:04 UTC 2 x86_64 x86_64 x86_64 GNU/Linux
i could not get manjaro to work, ubuntu 20 worked but CPU rendered, ubuntu 22 didn't work, ubuntu 23 didn't work, solus didn't work, i would have tried arch linux next probably if this didn't work as it's reliable but a lot of work to get set up
i read up on the AMD Radeon RX 7800 XT and it was barely supported by anything until mid January, even though Phoronix had made it work, they didn't really explain exactly what kernel versions they used, they only said ubuntu 23 and 6.2+ and it's already been my experience with 2 year old AMD gear, 5500M on a laptop, which was super hit and miss on anything except 5.15 - and it worked on this one too, but without acceleration
i've been using ubuntu on and off since 2008 or so, and it has always been the most irritating thing about the distro - always has a kernel metapackage that upgrades and breaks drivers, used to be network, sound and video, now mostly it's just video, and even this zorin, it wasn't even clear watching it do the upgrade, even disabling to upgrade while installing, that it installs a not working kernel 6.5 that gives nice black screens
considering the pain it just cost me, almost 24 hours of my life, and about 4 hours sleep, i just wasn't going to surrender to running windows on it just because it worked, i had to keep trying because if it can run a framebuffer it can usually run the GPU also
the linux kernel is shocking for AMD Radeon support these days, versions 4 and 5 were ok but 6 is a third world pothole filled road with pungee traps and unexploded ordnance waiting for you to fall into it
