I have an ASUS TUF A15 laptop with NVidia GTX 1660 ti graphics card. I installed Ubuntu 18.04 and tried everything here and here except manual install with .run files. I selected all options in Software & Updates one by one and rebooted. However, I could not get the Nvidia drivers up in Ubuntu, it always got stuck at boot (black screen). Also, it does not recognize an external screen, the default screen is “unknown display”.
I reinstalled Ubuntu freshly and went for the recommended approach in these forums: Just selected the recommended option in Software & Updates as follows:
I rebooted and voila, it was able to boot! I could even nvidia-smi with proper output and could see the nvidia-settings properly (previously it would show an empty window). However, Ubuntu > About still showed llvmpipe as the graphics device:
External and default screens were still not recognized. To solve this, I tried to reselect nvidia as follows:
sudo prime-select intel sudo prime-select nvidia reboot
At this point I was setback to the black screen at boot state! I tried both nomodeset or nouveau.modeset=0, but didn’t work. Now I am stuck again… Debug sh output is included. Please help, it already cost 1.5 days to me.
