I have the 2018 XPS 13, running Ubuntu. It worked pretty well on 16.04, until I upgraded past kernel 4.15. Now there's a bug where it either won't stay asleep, or when it wakes up the WiFi and Bluetooth devices are non-functional (even reloading the modules does nothing). I have recently discovered that disabling BT+WiFi via the keyboard function key before suspending avoids the problem, but it's annoying. I think it's also related to Intel making firmware changes for a Windows sleep mode that stays connected to WiFi.
I think this bug report is tracking the issue: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1799988 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1799988
