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?
GRUB_CMDLINE_LINUX_DEFAULT="quite splash i8042.reset i8042.nomux i8042.nopnp i8042.noloop
and everything was fixed I was able to unfreeze the touchpad and along with that the logo didn't disappear from the boot screen. ☺️
