Some keyboard keys not working in Ubuntu 16.04LTS and none working on Windows. But working fine in BIOS

Question

I have an Asus A540L laptop running dual boot on Ubuntu 16.04LTS and Windows 10 since last 1 year. Recently since 5-6 days, i've been experiencing keyboard and mouse issues. First, the left arrow button on my laptop keyboard seemed to get stuck. Then I switched to Windows and shockingly, none of the keys on my keyboard works at all(despite the keyboard works in Ubuntu). Then i went to BIOS during startup to check if it wasn't a hardware fault, and all the keys worked fine there. I even reinstalled xserver-xorg and libinput as well. Today, some of the keys(like, 'u',left arrow key,backspace key etc.) stopped working on ubuntu as well. But everything works fine in BIOS. So, i hope this may not be the Hardware, but kernel issue. Can some please help me with it?

Solution

Check your keyboard by booting into the BIOS. If it works there, then your hardware is OK.

Then run

sudo dpkg-reconfigure keyboard-configuration

in the terminal and choose the appropriate keybord. Asus should be in the list.
