black screen before login

[awkawaii]

Hi,

I just recently rebooted my laptop, but the screen turns black after loading the CentOS logo but before the login screen.
The following is the output when I try to run startx from the terminal as root using ctrl-alt-f2:

xauth: file /root/.serverauth.3233 does not exist

If anyone could help, I would be extremely grateful. I'm relatively new to Linux and CentOS so I'm not sure how to solve this problem.

How did you previously install the nvidia drivers?

[awkawaii]

I'm actually not sure about the drivers. When I tried running nvidia-smi before, it told me that the driver version is 352.93. When I tried installing the nvidia-x11-drv and kmod-nvidia files from elrepo repository, it gave me errors about dependencies. From what I remember, nvidia-x11-drv had a dependency on kmod-nvidia and kmod-nvidia had a dependence on some xorg nvidia file. However, I couldn't find the xorg nvidia file in the repository.

I have the same issue after installing the cuda tool kit from:

Please could you reply the full fix, if you found one yourself awkawaii?

Not just fixed? Cause this way it helps nobody.
