Keyboard not working after wake up or when I open the lid, Sony Vaio Ubuntu 18.04

  • 772

The keyboard is not working on my Laptop when the system wakes up from suspend mode or when I close the Lid and then reopen.

I made a little edit on the grub file, where I added this Line: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash atkbd.reset"

and again I have the same problem. Does someone know how to fix this ? Thanks.

    I've found the solution to this problem, and adding this line

    GRUB_CMDLINE_LINUX_DEFAULT="**i8042.direct i8042.dumbkbd**"

    to /etc/default/grub will work.

    As it says in that file, you need to run sudo update-grub before these new settings will take effect.

    However, the bad thing is that the Caps Lock and NumLock lights on the Keyboard will be either always ON or OFF.

  2. This is a working solution, but i8042.direct i8042.dumbkbd should be put in /boot/grub/grub.cfg directly, not in /etc/default/grub. All the details are found in this link, this is only an abstract: https://ubuntuforums.org/showthread.php?t=2224316

    1. Basically, you run:

      gedit /boot/grub/grub.cfg

    2. Find the string starting with linux... and put this at the end of the line:

      i8042.direct i8042.dumbkbd

    3. Then reboot and check if it works.
