@Boris, it's probably better you followup on these bug threads more specific to your Notebook and touchpad device: https://bugzilla.redhat.com/show_bug.cgi?id=1591307#c6

I don't think you have the same issue, the problem in bug 1526312 is a touchpad with missing descriptors. I think what you are seeing is the same i2c-hid touchpad power- management issue as other people or seeing on various ezbook models. This is currently being discussed here: https://bugzilla.kernel.org/show_bug.cgi?id=199821 The touchpad should work after a suspend/resume. You may need to do: sudo rmmod i2c-hid sudo modprobe i2c-hid After suspend-resume. ** Bug watch added: Red Hat Bugzilla #1591307 https://bugzilla.redhat.com/show_bug.cgi?id=1591307 -- 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/1728244 Title: Touchpad stops working after reboot on Apollo Lake Status in Linux: Unknown Status in linux package in Ubuntu: Triaged Bug description: On the Jumper EZBook 3 Pro (V4) laptop, using an Apollo Lake N3450 processor, if you install Ubuntu 17.10 (or less) with isorespin and use rEFInd as bootloader (this is the only way to get linux booting on this laptop) everything works out of the box, but after a reboot or two the touchpad stops working. Both in Ubuntu and Windows 10. The only way to restore functionality is to boot from usb key ubuntu 17.10 respined, or disassemble laptop and detach-reattach battery cable.
