Geforce GTX 1650 - nvidia-settings 'ERROR: Unable to load info from any available system'

  • 772

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 :

I am running Xubuntu 19.04 with 5.0.0-20-generic kernel and I've disabled 'Secure boot' in the BIOS.

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

  1. It looks like the Intel GPU is selected in your system (and disabled in BIOS) as the primary.

    Run the followng command:

    sudo nvidia-xconfig

    Then run this command to select the Nvidia: 

    sudo prime-select nvidia

    or, for Intel use the following command: 

    sudo prime-select intel

  2. I finally found a solution to the problem.

    1. Install drivers from PPA. There are many articles how to do that.
    2. delete /etc/X11/xorg.conf.
    3. switch to tty3 and shutdown Xorg: sudo systemctl stop gdm (for Ubuntu)
    4. Make xorg.conf skeleton file from log: sudo Xorg -configure :0
    5. Copy xorg.conf.new to etc: sudo cp /root/xorg.conf.new /etc/X11/xorg.conf

    6. Change driver name in section "Device":

      Section "Device"
    ### Available Driver options are:-
    ### Values: <i>: integer, <f>: float, <bool>: "True"/"False",
    ### <string>: "String", <freq>: "<f> Hz/kHz/MHz",
    ### <percent>: "<f>%"
    ### [arg]: arg optional
    #Option     "SWcursor"              # [<bool>]
    #Option     "HWcursor"              # [<bool>]
    #Option     "NoAccel"               # [<bool>]
    #Option     "ShadowFB"              # [<bool>]
    #Option     "VideoKey"              # <i>
    #Option     "WrappedFB"             # [<bool>]
    #Option     "GLXVBlank"             # [<bool>]
    #Option     "ZaphodHeads"           # <str>
    #Option     "PageFlip"              # [<bool>]
    #Option     "SwapLimit"             # <i>
    #Option     "AsyncUTSDFS"           # [<bool>]
    #Option     "AccelMethod"           # <str>
    #Option     "DRI"                   # <i>
Identifier     "Card1"
Driver         "nvidia"
BusID          "PCI:1:0:0"

    7. Reboot

    After that nvidia-settings will start properly.
