Removing "acpi_os_name=Linux acpi_osi=" from /etc/default/grub doesn't
fix this problem.

Bug description:
Hi

Ubuntu 18.04 went into standby mode with the mouse plugged in.
Then I've removed the mouse.

A few hours later I wanted to continue work (without mouse) and woke up my PC from standby mode.
Unfortunately the touchpad did not work.

So I put Ubuntu back into standby mode, plugged in a mouse and woke it up again.
Both Touchpad and mouse worked perfectly again.

Regards,

Ettore Atalan
