I run Ubuntu 19.04 on a VAIO VJF153F11X and have one single issue ever since I started using Linux: every time the system returns from suspend, either built in keyboard and touchpad won't work until I reboot - USB mouse and keyboard work fine.

Had the same problem on 18.04 and Linux Mint. I have already tried:

  • Upgrading and downgrading Kernel
  • Changing GRUB_CMD-LIMUX_DEFAULT line to "quiet splash i8042 direct i8043 dumbkd"
  • Reinstalling drivers with install xserver-xorg-input-alll

None of the above worked, what else can I try?

I had exactly the same issue with a Toshiba Satellite C50D-A-10K running Debian Buster. When resuming from suspend, both the keyboard and the touchpad wouldn't work. I followed the directions from this Ask Ubuntu answer, and changed the file /etc/default/grub adding i8042.reset i8042.nomux i8042.nopnp i8042.noloop to the line beginning GRUB_CMDLINE_LINUX so that it read

GRUB_CMDLINE_LINUX="i8042.reset i8042.nomux i8042.nopnp i8042.noloop"

Then I updated grub (sudo update-grub) and everything works fine now.
