I have a Sony Vaio SVF142C1WW with 64-bit Ubuntu 17.04 installed. Every time it resumes from being suspended, neither the keyboard nor touchpad work for a few seconds. Then the touchpad becomes responsive but the keyboard still remains non-responsive.
I recently upgraded from Ubuntu 16.10 where both the keyboard and touchpad did become responsive after a few seconds of non-responsiveness. I've tried answers to this and this but nothing worked. What else can I try?

and confirm you get this output
then, add the boot parameters
i8042.direct
andi8042.dumbkbd
to/etc/default/grub
. For example, runFind the line that begins
GRUB_CMDLINE_LINUX_DEFAULT=
and edit it to include the new parameters, so that after your edit it looks something likeSave by pressing Ctrl+O, exit by pressing Ctrl+X, and run
