I have recently encounter problem in connect external display/monitor in my Ubuntu system.

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.
**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.
SOLUTION:
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 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.
