Arrow Boot to blank screen or laggy monitors? Here is what worked for me.

My experience with the display link was not present. After first installing it, I was greeted with a blank screen on boot, and after I managed to bypass that I got extremely laggy monitors.

NOTE: I'm running ryzen 7 and Nvidia GTX 1660 Ti

Here is the process that fixed laggy monitors and makes everything smooth:

1. Update kernel to latest version with mainline
a .sudo apt-add-repository -y ppa:cappelikan/ppa
b .sudo apt install mainline
c. Open mainline GUI and install the latest kernel version
2. Restart and then Install display link driver (download the ubuntu version from their website)
a. sudo apt-get install dkms
b. sudo apt-get install libdrm0dev
3. Run the driver installation file
a. Right click the file and go to properties/premissions
b. Set the access to read/write
c. Set the execute to true
d. Run sudo ./<file-name>
5. Restart
6. Install nvidia drivers
a. sudo apt-get purge nvidia*
b. sudo apt-get-repository ppa:graphics-drivers
c. sudo apt-get install nvidia-driver-450 (this one worked for me)
7. Set the graphics card as main
a. Go to and open /usr/share/X11/xorg.conf.d/10-nvidia.conf
b. Paste
HTML Code:
  Section "OutputClass" 

    Identifier "nvidia" 

    MatchDriver "nvidia-drm" 

    Driver "nvidia" 

    Option "AllowEmptyInitialConfiguration" 

    ModulePath "/usr/lib/x86_64-linux-gnu/nvidia/xorg" 

    Option "PrimaryGPU" "yes" 

EndSection 
The important line here is PrimaryGPU. I think I had laggy monitors because ubuntu was running everything over the integrated GPU
8. Restart

Hopefully it works.
