This question already has an answer here:
I was trying to dual boot Ubuntu 18.04.1 LTS alongside Windows 10 on my laptop.
I got the USB and followed the video and everything worked up to where I clicked Try Ubuntu without installing and when the desktop loaded I was not able to use my touchpad. A wireless mouse worked but I was not able to click.
Someone told me
You need to boot the installation media with an additional boot parameter
nomodesetand also when booting the installed system until you install the Nvidia proprietary drivers.
I have no clue what the user means by any of this as I am very new to Ubuntu, can someone explain how to do these things and what it means? Thank you in advance.
