[Solved] nvidia driver – Fatal server error: no screens found

X server (init 5) startup issues after deploying NVIDIA graphics driver

You may end up breaking your Linux system’s graphics console (x session start up) after you deploy NVIDIA drivers.

If you have a look at your X server log you will notice the following. I had faced the same problem and I was able to solve it. I thought it would help you as well, please read through.


Following is the snip of  X server log:

Step 1: Make sure your NVIDIA driver is installed properly and your X server is running on Graphics card. In the following screenshot, the X server is NOT running on the graphics card. To fix this, do as in step 2.


If “nvidia-smi” command is not found, you may have to download suitable nvidia driver from the official website.

Note: Make sure you enter in to run-level 3 before installing nvidia driver. Also you have to blocklist “nouveau” driver before installing nvidia drivers.

Step 2:  Fix  xorg.conf file. Generate new xorg.conf  using “nvidia-xconfig” as follows. This will  replace your existing xorg.conf file  if any. However, it takes backup of your old config file. This will add proper entries of nvdia graphics device, screens etc., to the xorg.conf file.

# nvidia-xconfig --no-xinerama --probe-all-gpus --use-display-device=none

Option “–use-display-device=none” will help you to  resolve “no screens found ” issue. If your graphics machine is hosted in datacentre and you have not coonected any monitor to it, you must use this option.

Step 3:  Switch to run level 5

#init 5

Now you should be able to start your X session.

Step 4 :  Make sure your Xorg (X server) is running on graphics card by running “nvidia-smi”. See below screenshot.


Notice that “/usr/bin/X” is a process running on GPU using GPU cores and memory.


Hope this helped.
