For anyone with this laptop... Upgrade to a newer kernel and install the latest Intel i915 firmware files. When the kernel installs it will warn you about which files you need. This will get rid of that FIFO underrun problem. (I chose drm-intel-nightly)
Most importantly adding i915.edp_vswing=2 to the kernel parameters should fix the terrible screen flickering. I hope this helps! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1739936 Title: Screen flickering on Razer Blade Stealth (Late 2017) - [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun?
