  • Just got my Late 2016 Razer Blade Stealth QHD and installed Ubuntu 16.10 on it. Aggressive screen flickering at native resolution. Upgrading the kernel to 4.10rc4 and installing Intel Kaby Lake DMC firmware make this less aggressive/more usable but I still see the flicker occasionally. dmesg shows: [ 182.918947] [drm:intel_cpu_fifo_underrun_irq_handler [i915]] ERROR CPU pipe A FIFO underrun Installing+running Intel Graphics updater for linux v2.0.3 does not help.
