I am having problems with a Ubuntu 20.04 LTS bootable USB on a Gigabyte laptop from 2019 with a nVidia GPU. All RAM tested with Memtest86 for 4 passes. Prime 95 stable on Windows 10.

In the Try Ubuntu / Install Ubuntu opening screen, sometimes it just freezes completely, requiring a hard shutdown.

If it doesn't freeze and if I do get to the desktop, the keyboard does not work for some applications. For example, the keyboard works for the launch menu, so I can type "term" and launch a terminal. However, the terminal does not accept any input! Likewise, for firefox, the address bar does not accept any keyboard input. If I Ctrl-Alt-F3 to a console, I can type just fine.

The freezing can be avoided by choosing the safe graphics option, but the keyboard issue remains. Also, if I actually try to Install Ubuntu from the safe graphics option, the dialog box is so large that I cannot see (and press) the back/next buttons on the bottom.

Questions: Are there any boot options which will allow the regular (non-safe graphics) option to work without freezing?

How can I get keyboard input to work reliably, since terminal and firefox are non-responsive to the keyboard?
