Hello,
I have finally bought a computer with a Nvidia graphics card, and I cannot find why the drivers are not working, even though the card is recognized by the OS and the recommended driver 525 is installed.
$ nvidia-smi
NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
$ uname -r
5.19.0-40-generic
$ nvidia-settings
ERROR: NVIDIA driver is not loaded
(nvidia-settings:5756): GLib-GObject-CRITICAL **: 23:57:54.696: g_object_unref: assertion ‘G_IS_OBJECT (object)’ failed
** (nvidia-settings:5756): CRITICAL **: 23:57:54.697: ctk_powermode_new: assertion ‘(ctrl_target != NULL) && (ctrl_target->h != NULL)’ failed
ERROR: nvidia-settings could not find the registry key file or the X server is
not accessible. This file should have been installed along with this
driver at
/usr/share/nvidia/nvidia-application-profiles-key-documentation. The
application profiles will continue to work, but values cannot be
prepopulated or validated, and will not be listed in the help text.
Please see the README for possible values and descriptions.
I have already tried to purge and reinstall the drivers and to prime-select.
If needed, here is the bug report:
nvidia-bug-report.log (598.7 KB)
Is there anything I can do?
Thank you in advance for your help.
There are no kernel modules installed, also secure boot is enabled.
Please disable secure boot in bios, the try reinstalling kernel headers
sudo apt install --reinstall linux-headers-$(uname -r)
afterwards, please post the output of
dkms status
Thank you for your answer. I have reinstalled the kernel headers and disabled secure boot.
The output is:
$ dkms status
nvidia-srv/525.105.17, 5.19.0-40-generic, x86_64: installed
The outputs of nvidia-smi and nvidia-settings are normal now.

However, I can access the desktop environment with TeamViewer only. The screen that is plugged to the HDMI port of the graphics card stays black at boot. The screen isn’t even detected by Ubuntu, and this was not the case before.
Do you have any idea why? Should I downgrade to a previous version of the driver?
Rather looks like the driver is loading too late. Please create a ne nvidia-bug-report.log

Thank you again for your help!
You have installed a dummy driver. Please delete /usr/share/X11/xorg.conf.d/xorg.conf
