Dual monitor not working after nvidia driver install

[tejise]

After installation with nouveau drivers monitors were working okay, but after nvidia drivers install it does not.

startx terminates succesfully showing no errors.

xrandr output gives only one resolution and nvidia-settings has graphics information and thermals nothing else.

System has 3 gpus 2x 3060ti and 1x 3080.

In about section under graphics shows llvmpipe (before installing nvidia drivers it was showing llvmpipe 3 times).

Drivers where installed from epel, latest-dkms.

It is first time i'm setting up this and searched everywhere before posting on forum. No solution found, tried to make xorg.conf but then system hangs at boot.

What is the output from uname -a ? How did you install the nvidia drivers and from where?

Drivers where installed from epel repo i have switched from graphical.target to multi-user and installed while i was root.

Is it possible that security policy interfere with xorg or nvidia ?

Can this be a problem?

EPEL doesn't ship the nvidia drivers. Maybe you meant ELRepo or rpmfusion? And yes, those errors may explain your problem.

i have followed this guide
Maybe i was wrong, it is some nvidia repository.

Right now i have installed nvidia driver with .run file and everything works perfectly (and i was doing that on some other linux distros but i though it should work with downloading packages).
Will see how it is going to be.

After reboot it does not work again

ELREepo packages do not support Stream so if you installed from there, that would explain why they do not work. They are designed only or use on RHEL or one of the RHEL clones (which Stream is not). If you installed them from rpmfusion then it will have added a dkms package and wwill rebuild the nvidia kernel module when it thinks it needs to at boot time.
