Brand new XPS 13 9380 arrived a couple of days ago from Dell with Ubuntu 18.04 preinstalled.
Flickering started immediatelly post boot and it was constant.
I updated BIOS from 1.1.1 to 1.2.1, tried i915.fastboot and i915.enable_rc6 combinations to no avail.
Updated to Ubuntu 19.04 and kernel-5 to no avail. However flickering changed from constant to only if there's a screen refresh.
