I have the same problem, with Fujitsu Lifebook E557, Ubuntu 18.10, kernel 4.18.0-17-generic.
After resume from suspend, touchpad doesn't work at all. Keyboard works somewhat, but some keys are randomly "repeeeeetedddd". Reboot doesn't help, but need to to turn the machine off and on again. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1769792 Title: Keyboard and Touchpad do not work after suspend/resume Status in linux package in Ubuntu: Confirmed Bug description: My laptop is a Toshiba Satellite C850D with updated 18.04 installed.
