Ubuntu – Nvidia GTX 1650 not detected in Ubuntu 18.04.3


I recently bought this machine: ASUS TUF FX505DT – AMD Ryzen 5 3550H with GTX 1650 4GB. It came with Windows 10 preinstaleld. The GTX 1650 graphics card worked in Windows without any issue. After I cleaned my SSD, disabled Secure Boot in BIOS and installed Ubuntu 18.04.3, the graphics card is not recognized.

I added graphics-drivers/ppa, purged all existing NVIDIA packages, installed nvidia-driver-430 (tried 435 as well), but still it didn't work. I've also installed ppa:xorg-edgers/ppa using the following command:

sudo add-apt-repository ppa:xorg-edgers/ppa

This what Additional Drivers shows before installing the drivers:

This is the About info regarding the machine:

Product model is showing as Unknown in the Additional Drivers settings.

After installing the drivers, if I reboot and try to login into Ubuntu (Xorg), it freezes in the login screen or logs out immediately. But Ubuntu (Wayland) login works fine. But even with all the drivers installed, the screen flickers constantly in Wayland.

Best Answer

From the poster's comment to a detailed fix;

Do not add graphics drivers ppa and if you did it, remove everything including the ppa.

Open up the Additional Drivers from menu and select the proprietary tested driver and reboot.

Then create the directory and copy the file in it by following commands:

    sudo mkdir /etc/X11/xorg.conf.d
    sudo cp /usr/share/X11/xorg.conf.d/10-nvidia.conf /etc/X11/xorg.conf.d

Then add Option "PrimaryGPU" "Yes" to the OutputClass of the following file

sudo vim /etc/X11/xorg.conf.d/10-nvidia.conf

It should look like this in the end:

Section "OutputClass"
    Option "PrimaryGPU" "Yes"    
    Identifier "nvidia"
    MatchDriver "nvidia-drm"
    Driver "nvidia"
    Option "AllowEmptyInitialConfiguration"
    ModulePath "/usr/lib/x86_64-linux-gnu/nvidia/xorg"

Then reboot. After rebooting, try nvidia-smi command to see if it works.

I got gtx1660ti working with this soluiton well.
