Hello,
I was updating my nvidia driver to 525.xxx and when I reboot I am stuck at the gnome display manager.
If I boot at runlevel multi-user I got my prompt everything.
But unable to pass the gdm starting.
Any idea how I can get out of that issue ?
Thank you in advance !
So I fixed my issue at the end, I did the old school install from the NVIDIAXXX.run from a terminal in multi-user.target
Worked like a charm 
as usual…
Actually to problem came back after reboot.
So I can start the gdm after installing the driver manually and I got my desktop, but as soon as I restart I got stuck again at the Starting Gnome Display Manager again…
So I am kinda stuck in the water…
What I did try so far:
rmmod nvidia-dmr
rmmod nvidia-modeset
rmmod-nvidia
Those got me back the nvidia-smi function
I did a dnf autoremove nvidia* and re installed the driver from scratch
I am installing NVIDIA-Linux-x86_64-525.78 and the 515.86
Soooo… it looks like the 525.xxx are not compatible with 8.7 (4.18.425-3.1) on my machine at least.
I have few but not with that OS specific so can’t really check.
This system runs a dual epyc 7601 on an supermicro board H11DS.
The graphic card is a 3090Ti
Now after getting back to NVIDIA-Linux-515.86.01 my system is back to normal
