I have this bug, at least partially. My keyboard keeps working, but touchpad doesn't work after reboot. I originally commented in this report:
https://bugs.launchpad.net/ubuntu/artful/+source/linux/+bug/1723799 but they asked to create a new report. This is what I said there: ======================== I too am affected now. After suspend+resume, my touchpad isn't found. Rebooting doesn't help: I really have to turn the machine off and on again. I can attach mouse, and then if I try to open touchpad settings in Input Devices settings (I use Kubuntu), it says that Touchpad isn't found, and xinput doesn't show it either. - Fujitsu E556 laptop - 4.15.0-20-generic #21-Ubuntu I still have Ubuntu 16.04 on one SSD with the kernel 4.4.0-119-generic, and the issue doesn't appear there. I think the issue didn't appear on Kubuntu 17.04 either. I didn't try 17.10. The workaround mentioned in the original post didn't work for me. When I ran sudo modprobe i2c-hid, I got this message: rmmod: ERROR: Module i2c_hid is not currently loaded The command sudo modprobe i2c-hid completed, but the touchpad didn't start working. ====================== As was asked by jsalisphury, I tested this with the latest mainline kernel (generic) too: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.17/ The problem wasn't affected – the touchpad doesn't resume. I hope this helps. I'm not sure if *I* should add the 'kernel-bug- exists-upstream' tag though, because I'm not OP, and my problem is slightly different.
