Ok I nearly lost hope, since not being able to figure it out.

PLEASE. SEND. HELP.

_ First: this might gonna get a long one, but I‘m desperately looking for help!
Second: I‘m a total newb on Linux, so I have really limited Linux know-how.

Specs:
Asus ROG Strix G15DS-R7700X088W
AMD Ryzen 7 7700X
NVIDIA GeForce RTX 3070
2x 1TB SSDs; 1x M2 NVME with W11 running, 1x SATA

Goal:
Running Dual Boot with W11 on the first, M2 SSD (already running fine) and Linux (Nobara preferred) on the second, SATA SSD

Distros I tried:
Nobara 39
Fedora 39
Fedora 38
Ubuntu 22.04
Pop!_OS

Problem I run into:
I can‘t boot even from the LiveUSB without the „acpi=off“ option. If I do, I get just a black Screen (with Backlight still on) or, if I get into the Grub options first, there‘s only „booting command list“ visible but nothing else happens (even with „quiet“ disabled, no info on the Screen at all).
One thing I noticed, since my Keyboard, Mouse and Mousemat (Razerfly) have lighting, when I try to boot without the acpi=off, they go dark. And stay dark. With acpi=off the keyboard alone goes dark but then lights up again after 2-3 seconds.
If I run it with acpi=off, I can boot and install, but I then have to boot every time with acpi=off. This leads to the graphics driver not being recognized by the OS and running always in 1024x768 „software rendering“ resolution (even with proper drivers installed and enabled and nouveau on blacklist). So just let „acpi=off“ enabled isn‘t an option.

I did, after researching for several hours, try with various other options (nomodeset, acpi=ht, pci=biosirq, noapic, nolapic, and so on, tried a ton of those) but nothing did the trick - always black screen of death without acpi=off.

I did update my BIOS to the latest Version (306), did try every possibilty of options enabled/disabled (Fast Boot, Secure Boot, IOMMU, acpi settings in BIOS, secondary on-board Graphics,…) with no change.

Since I ran out of options (in relation to my google and reddit search skills), knowledge (total newb on Linux) and possibility to ask friends (that know more about linux than me), I‘m desperate enough to ask for help.

You are my last hope, before giving up on Linux with my PC.

If someone has an idea I could try or even a solution, I‘d be endlessly thankful!

If I missed some info or something is needed, don‘t hesitate to as for specific details._
