`nvidia-xconfig` breaks boot

Question

I would like to test some GPU overclocking add fan speed settings on my machine.

For that I need to enable the Coolbits option in the Device section (Enabling overclocking):

sudo nvidia-xconfig --cool-bits=12

It seems that this line above will create a xorg.conf file, but the Coolbits option does is not written under Device, but under Screen configurations.

Even so, if I only create the xorg.conf file with sudo nvidia-xconfig, and then manually add Option "Coolbits" "12" in the "Device" Section to make it look like this:

Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
    Option         "Coolbits" "12"
EndSection

when I restart the machine, Ubuntu 18.04.4 does not get past the loading screen: Ubuntu 18.04 hangs at boot after running `nvidia-xconfig`

Others encountered the same problem:

I couldn't find a clear solution. How can I make the nvidia-xconfig work properly?

Can you boot with that xorg.conf if you run sudo depmod then reboot ? — Parsa Mousavi, Jun 25 '20 at 10:03
I suspected the driver dependencies , so I thought it might solve the problem.In fact I suspected the line Driver "nvidia" in the config file.Glad to see it solved :) — Parsa Mousavi, Jun 25 '20 at 11:01
Actually this does not work. I forgot I was on the Intel GPU. — Sandu Ursu, Jun 25 '20 at 19:35
I've managed to solve my issue by following the instructions here. It did boot well. Also, I did run nvidia-settings and under PowerMizer I could see Editable Performance Levels. — Sandu Ursu, Jun 25 '20 at 23:53

Run :

sudo depmod

It will check all the module dependencies and updates the file /lib/modules/5.3.0-46-generic/modules.dep.
