Ubuntu 18.04. 1.. Laptop keyboard and track pad not working

[Uday_Sama]

I'm using a live usb of ubuntu 18.04. 1.. But I didn't get any login option.. It directly loaded the desktop.. But my laptop keyboard and track pad aren't working.. Only ext mouse is working.. That too only to move cursor. Please help

That's the point of a live boot.

Try

sudo apt-get install xserver-xorg-input-all

somehow, with either an external keyboard or the on-screen keyboard. Otherwise maybe https://askubuntu.com/questions/908918/updated-from-16-04-to-16-10-the-keyboard-and-mouse-no-longer-works-after-gettin can be of help.

That's the problem.. I'm unable to connect ext keyboard.. Mouse just moves.. Track pad doesn't work.. Where should I type commands?

Can you get to the settings? There should be an on-screen keyboard somewhere in the Universal Access options I think.

You can't click either? Well then you're pretty much out of options.

Laptops are always a pain in the *ss. 
Try those kernel commands from GRUB: acpi=off if nothing, acpi_osi="Linux", acpi_osi="Windows" (not all the options, try each of them)

Just press E after getting into the USB live before booting ubuntu, and put the kernel commands after "quiet splash" or something like that

This probably isn't a driver problem, just the ACPI not enabling those devices when they don't detect windows, the usual vendor cr*p
