No display output on a Debian Testing host with a RTX 4060Ti 16GB

Hello out there, I have quite new Debian system with GeForce RTX 4060Ti 16GB and Core i7-14700 on a MSI Z690-A WIFI DDR4. The system boots up but does not open a display manager or something else.
uname -a > Linux jupiter 6.11.5-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.11.5-1 (2024-10-27) x86_64 GNU/Linux

and during bootup it creates two Xorg.0.log files successively. I don’t know if this normal. But look on the stats of these two files:

So the 2nd file is created after the 1st was closed?

I attach the two files. But the 2nd logfile says that the xserver actually starts and the kernel modules are getting loaded. But nvidia-smi on the other side, says: No devices were found
At the end ,y dmesg is fludded with this two lines over and over again:
NVRM: GPU 0000:01:00.0: RmInitAdapter failed! (0x23:0x65:1426)
NVRM: GPU 0000:01:00.0: rm_init_adapter failed, device minor number 0

nvidia-bug-report.log.gz (611.7 KB)
dmesg6.txt (91.2 KB)
Xorg.0.log (8.4 KB)
Xorg.0.old.log (9.4 KB)

Can anyone find a clue here, in which state my driver is?
Thanks a lot

Turns out that this problem doesn’t occur with the original NVIDIA driver from the site but with all Debian installations. I tried it with stable, testing and sid, everytime it stucks with Xorg log file telling me: "no screens found(EE) " and shortly after that a new Xorg log file that doesn’t give me anything about an error but lacks any display detection. And then lots of

Blockquote NVRM: GPU 0000:01:00.0: RmInitAdapter failed! (0x23:0x65:1426)
NVRM: GPU 0000:01:00.0: rm_init_adapter failed, device minor number 0

in the kernel dump. So it’s on Debian’s side.
