Public bug reported:
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. This is mesg |
