Any idea on what to do?

So I have two monitors secondary one of which I rotate to the left and use nvidia settings but does not save those settings after reboot I have tried saving the x config file to /etc/X11/xorg.conf both by merging and not merging as well as using root access to no avail.

I am trying to plug an external monitor to my laptop with a HDMI cable in order to have a dual screen.

When I do so, nothing happens, the external screen is not recognized at all. I think that's because the driver of my laptop's video card is not properly installed/enabled.

To install the drivers, all I did was

sudo add-apt-repository ppa:graphics-drivers/ppa

and then used 'additional drivers' GUI to setup nvidia-driver-430 on my system.

I rebooted my machine and nothing changed, the external monitor is still not recognized...

When I try to launch nvidia-settings, I get this error :

ERROR: Unable to load info from any available system


(nvidia-settings:3585): GLib-GObject-CRITICAL **: 17:36:06.267: g_object_unref: assertion 'G_IS_OBJECT (object)' failed
** Message: 17:36:06.271: PRIME: No offloading required. Abort
** Message: 17:36:06.271: PRIME: is it supported? no

Here's the output of nvidia-smi :

This is really annoying... Anyone could help me out on this ? Thanks in advance

(I'm aware there are several questions with a similar title but they either don't have answers, are very old or don't apply to my situation.)

I'm using Ubuntu 18.04.2, my GPU is a GeForce 840M and the driver version is nvidia-driver-430 (installed from the Softwares and updates panel)

So I can't seem to use the nvidia gpu anymore. I have no idea what caused this.

sudo nvidia-settings

gives the following output:

ERROR: NVIDIA driver is not loaded ERROR: Unable to load info from any available system

It does open an Nvidia panel but without the usual settings and just the two PRIME profiles (Nvidia performance mode and intel power saving mode ).

sudo nvidia-smi

gives the following error :

NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

I've tried a few things like purging and reinstalling the driver or using an older one , with no luck. I've also tried downloading and running the .run driver from the nvidia website but it failed to install.

I'm looking for advice on what to try next to have it working again. Thanks for your help :)

I'm up to setting up some mining rigs running Ubuntu. I use Nvidia GTX 970 and GTX 780 GPUs. I installed the 16.04 LTS server distro and it's working fine. I can tweak some GPU params using nvidia-smi. However, over- and underclocking can only be done with nvidia-settings utility which I have trouble running. The error msg is this:

Failed to connect to Mir: Failed to connect to server socket: No such file or directory. Unable to init server: Could not connect: Connection refused.

ERROR: The control display is undefined; please run nvidia-settings --help for usage information.

I looked thru internet a lot. Nvidia-settings needs graphic interface, so I installed Xorg, Ubuntu Desktop and everything I could find on the subject. The computer boots into graphic desktop now, however, nothing really happens after a login, the screen is pretty empty, no icon or anything. Nvidia-settings still not working.

I am accessing the computer via SSH, I created the xorg.conf file, I am using custom edid files to emulate monitors. I've also set coolbits to 31.

Maybe I should just install the full graphic version now, I am sort of clueless what to do next.
