I run Ubuntu 19.04 on a VAIO VJF153F11X and have one single issue ever since I started using Linux: everytime 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 GRUD_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 here, and changed the file /etc/default/grub adding
i8042.reset i8042.nomux i8042.nopnp i8042.noloop
to the line
GRUB_CMDLINE_LINUX_DEFAULT.
Then I updated grub (sudo update-grub) and everything works fine now.
