I am trying to dual-boot install Ubuntu 18.04. Upon booting from a USB stick and choosing either 'Try Ubuntu without installing' or 'Install Ubuntu' in the GRUB menu the screen glitches and stays that way,

I thought its a problem between the GUI and the hardware so I set the parameters 'gfxpayload' to 'text' and 'boot' to 'single' to boot it with the command-line (the idea being to install graphics drivers)

see pic

but it glitches just as well (although it does start the command-line.

see pic

I can get into the GRUB terminal just fine though.

I might have missed something obvious? What would be the next thing to try?

The computer and screen work well with Windows 10. The display is a Samsung C32F391 and the graphics card NVIDIA GeForce RTX 2060 SUPER.

When you get to the grub menu you can add the nomodeset boot option. nomodeset tells the kernal to not load the video drivers until the X window server is started. To add this option do the following:

  1. Get to the GRUB boot menu
  2. Highlight the the option that you want to boot to
  3. Press e
  4. Find the line that has linux at the start
  5. Add nomodeset to the end of that line
  6. Press Ctrl-x or F10 to boot.
