I turn off wayland setting and turn on X11 And whenever I go to Settings > About my laptop freeze.


Additionally, I don't see display layout to setup monitor. I have Dell Dock and tried with DP1 and HDMI cables but didn't work.


I tried all possible solution, purge and install nvidia drivers, ubuntu-drivers autoinstall, OS re-install with safe graphics.

Appreciate your time.


EDIT


I have multiple drivers from the Additional driver window. I tried green highlighted drivers.

What I did?



  • Select drivers and install it. Click on restart now button.

  • After restart, open a terminal and run command sudo ubuntu-drivers autoinstall. Afterwards, reboot.

  • Go to Settings > Display. No effect. Same window as previous.

I have tried multiple tricks to find a solution inside the Linux system. Afterwards, I have tried to find a solution for the Dock driver connector to display my external monitor. And it works, here what I have done:



  • Download external Nvidia drivers as mentioned by kepler-22. https://www.nvidia.com/download/index.aspx

  • Go to terminal and run downloaded file from above link: sudo ./filename.run In my case, I did sudo ./NVIDIA-Linux-x86_64-525.85.05.run

  • Download Ubuntu drivers for Dell Dock from https://www.synaptics.com/products/displaylink-graphics/downloads/ubuntu

  • Open downloaded folder. It has a .run file. In my case, sudo ./displaylink-driver-5.6.1-59.184.run

  • sudo reboot

  • Additionally, I had to install sudo apt-get install evdi-dkms

  • Afterwards, I got an external display (LG), Dell Dock with MSI laptop.
