Hello,

My second monitor cant show up after nvidia drivers update. I’m using 580.126.18 driver and 6.18.13-200 kernel.

I tried using modprobe nvidia command but nothing appears.
In other post i see someone has similar error and editing /etc/default/grub adding lockdown=none could fix but still nothing.
I triend to force reinstall akmod and dracut and on the grub change the kernel version but nothing so i dont know whats happening.

Thanks.

Hi and welcome,
can you please gives us the output of:
inxi -Fzxx.

Open the terminal
type inxi -Fzxx
Select with your left-mouse button pressed the complete text, instruction plus output so that it is marked. Right-click the text and select Copy.
Then here in the answering window you click on the </> button in the toolbar of this window. Three new lines appear, one with 3 ’ signs, one with text in blue and again one with 3 ` signs.
Right click the text in blue and select Paste.
Now the text is pasted into your answer in such a way that it is easy to be read.
Thanks.

This command is only for manually loading a module into the kernel.
To see if the nvidia modules are loaded use lsmod | grep nvidia
To identify the current driver version use modinfo -F version nvidia and
to see the licensing version use modinfo -l nvidia

It seems the most common cause of this type issue may be something that causes the newly built driver to be corrupted. That can usually be fixed with sudo akmods --rebuild --force.

The inxi output that was requested above is also usually very helpful.
