My laptop is "Lenovo Ideapad slim 3i". I was trying to install Ubuntu with dual boot Windows 10 with a USB.
When the installation process starts asking: "Try Ubuntu" or "Install Ubuntu", but my mouse doesn't work. With the help of keyboard I chose try Ubuntu then it opens a Ubuntu interface - here also my mouse doesn't work and screen brightness neither increase nor decrease.
I tried by enabling and disabling secure boot. I face same problem in both the cases.
Also when I try to install (without working mouse) option for normal installation is not there only minimal installation is allowed.
