I'm testing Xubuntu 18.04 and have the same message in kern.log:

Mar 15 17:26:21 Xubuntu-18-04 kernel: [ 543.782137] [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun

I have experienced some "weird" screens.Please have a look here: http://i.imgur.com/x2vCDj3.png

Running uname -a gives:

Linux Xubuntu-18-04 4.15.0-12-generic #13-Ubuntu SMP Thu Mar 8 06:24:47 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
