I've just received another laptop so I now own 2 of them. The new one is more recent and... everything works out of the box (trackpad, buttons, suspend...).
The BIOS is more recent and is reported as: DMI: Jumper EZbook/P313P, BIOS JUMPER10x.P8.WP313P.NhNAUHL02 11/06/2017 While my older Jumper is: DMI: Jumper EZbook/P313R, BIOS JUMPER2x.P8.WP313R.NHNAUHN05 09/30/2017 We can notice that BIOS is more recent and has almost no options available (basically only Security and Boot tabs), but also that model is P313P instead of P313R. I compared output of lspci/lsusb/lshw/dmidecode and there seems to be no real differences on reported hardware except maybe the value of "Interleaved Data Depth" reported as 2 on the old and 4 on the new. You'll find reports attached. Last I opened both laptops to check hardware and PCB are different. This now really seems to me like a BIOS issue on the 09/30/2017 version. Did some of you try to contact Jumper by email ? (I did using the only email I found: mon...@jumper.com.cn, but with no answer yet) -- 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.
