Why won't mouse and keyboard work in Ubuntu?

Question

linux

Ubuntu 18.04
2 graphics cards (intel and nvidia), Asus Vivobook.
Tried installing bumblebee.
The problem arose after this command

sudo apt-get install bumblebee bumblebee-nvidia primus linux-headers-generic

and the next reboot, the keyboard and mouse do not work, but the desktop displays all the folders etc., I can use the keyboard and mouse before logging in, but when I enter all the passwords, I can’t move the mouse and use the keyboard on the desktop.
On the desktop, the time switches and the charging indicator changes, and the keyboard backlight key also works on the keyboard, help me, please)
