Thank you for all these details.
I have two questions for you:
Can you tell me which version of the GNU Nouveau driver Manjaro uses (libdrm-nouveau) ? Is it higher than version 2.4.124-2 ?
Could you try booting the Debian 13 (testing) installer linked below and tell me if you see anything on the screen or if it remains black ?

I donāt know if this helps at all, but I successfully swapped out my RTX 3060 with an RTX 5070 Ti yesterday with no issues save for a grey screen on boot while BIOS and card shook hands. Did hard reboot and everything launched and was recognized perfectly without any tinkering.
My hardware: i5-13600KF, ASRock Z790 Pro RS; 64GiB RAM
I am on a Debian-based distro (PikaOS 4) running Linux 6.15.0-pikaos and GNOME 48
Before swapping cards I made sure I was on nvidia-open-driver-570 (which is 570.153)
About to try opening 575 today (I preferred it with the 3060 but the new kernel wasnāt ready for it so had to switch back to 570āthough 575 has been patched for 6.15 by Pika as of today.
Hope you find a solution to your issue!
Thank you all for your helpful ideas.
Ultimately, the problem was my motherboardās BIOS (Asus X570), which was causing problems with an Asus Prime RTX 5070 Ti graphics card when configured in UEFI with CMS compatibility enabled.
In this configuration, only Manjaro and Windows 11 would install and/or boot; other operating systems would crash 2 to 3 seconds after Grub booted when accessing the RAM disk.
I had to disable this CMS compatibility to get it to work with this new RTX 5070 Ti card. Frankly, this situation is hardly desirableā¦ if the BIOS becomes reluctant to run certain hardware components, itās not going in the right direction and it doesnāt make our lives easier, quite the opposite in factā¦
Thank you for your helpful advice and I look forward to reading you on phoronix :)
Thank you for your message.
nope, on Manjaro ive installed not nouveau drivers (nouveau drivers was used only to go to desktop and install properiaty drivers with open kernel modules from nvidia) so i dont have libdrm-nouveau but libdrm 2.4.124-1 exactly
ill check debian maybe even today
Edit:
But idk if its reason to check clean Debian since Kubuntu 25.04 has exactly that same both libdrm-amdgpu1 2.4.124-2 and libdrm-nouveau2 2.4.124-2 with kernel 6.14.0-15 and testing release of Debian 13 has only kernel 6.12 (i couldnt force drivers to work with that kernel and ive tried many times on many distro releases) and results are same (ofc only with nvidia-driver-570-open). SDDM login window has no hdmi output signal regardles if its on X11 or in Wayland. And ofc novue drivers works fine in that matter just dont recognize display device correctly and have worse performanceā¦
Ah and Manjaro ive tested only 25.01 25.0.2 and 25.0.3
So mine advice for you is first of all update kernel to at least 6.14 so propably u would need to use experimental Debian release not the testing one
And i have always CMS disabled
Installing fresh Ubuntu Gnome 25.04 and Manjaro 25.0.3 with Gnome (kernel 6.14) was always freezing OS during driver installation for me
