I haven't met your issue on X1 Carbon 5th, but Lenovo did ship different touchapd/trackpoint on X1 Carbon 5th. And you didn't provide the whole dmesg with pnd ID in it. so I can't tell if the hardware or firmware is the same as I tested. Could you try smbus mode first on mainline kernel? 1, download kernel package from: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.15-rc5/ I am not sure if it can be installed and work well on debian. It enabled RMI4_SMB and SYNAPTICS_SMBUS. 2, boot with this kernel with "psmouse.synaptics_intertouch=1" in your kernel cmdline. If trackpoint still can not work, please send me the dmesg.
