Comment 3 for bug 1791427

Hi, for me the following combination for ubuntu 18.04 using x1c6 with nfc (20KG) seems to be working:

- touchpad and trackpoint both enabled in bios
- nfc disabled in bios (because i dont need it, dont know if it would work)
- linux (s3) sleep in bios
- upgrading to the newest kernel, i am using 4.18.7 from http://kernel.ubuntu.com/~kernel-ppa/mainline/
- removing the blacklisting of i2c_i801 by commenting the line blacklist i2c_i801 in /etc/modprobe.d/blacklist.conf
- enabling the tlp settings in /etc/default/tlp to:

        USB_AUTOSUSPEND_DISABLE_ON_SHUTDOWN=1
        USB_AUTOSUSPEND=0
        RUNTIME_PM_BLACKLIST="00:1f.4"

- upgrading libinput to 1.11.3, by manually downloading libinput10_1.11.3-1_amd64.deb libinput-bin_1.11.3-1_amd64.deb from cosmic (ubuntu 18.10) https://launchpad.net/ubuntu/+source/libinput and installing with sudo dpkg -i libinput10_1.11.3-1_amd64.deb libinput-bin_1.11.3-1_amd64.deb (This one is scary but upgrading didnt break any dependencies... atleast for me). This should at least fix https://gitlab.freedesktop.org/libinput/libinput/issues/46

upgrading libinput was the most important part and other steps maybe can be omited. However, without the tlp settings the trackpoint (sometimes) doesnt survive suspend.)
