I have dual booted my macbook with ubuntu 20.04. As explained in the steps, I have downloaded ubuntu 20.04 iso file for desktop. I have transferred this iso file to my 16 gb USB, and opened sufficient place for UBUNTU and SWAP parts. Next, I have restarted my macbook by holding down option key. I have selected the efi boot option which is gold. I have then clicked on "Ubuntu" to proceed. After that, I have seen a screen with "Try Ubuntu", "Install Ubuntu", and the language options. However, when I move the trackpad to "Try Ubuntu" part or "Install Ubuntu" part; the mouse cursor freezes, and does not move. For solving this problem, I have watched several youtube videos but cannot find the solution. I have also read some key combination recommendations, and applied them. But still the recommended key combinations also do not work. If you have an idea about the solution of this problem/solved this problem before, I will be thankful if you share your ideas/solutions about the problem I am experiencing.
