When I lock my screen on my Lenovo T450s and the notebook sits in the dock (two external screens attached), one of the three things happen when I come back after some time and try to unlock (so it went to power safe inbetween): * Most of the time the computer was just shut down and I have to start it again * Sometimes the notebook screen flickers weirdly and one of the two other screens show pixel garbage * The notebook screen shows the lock screen but is completely frozen. Occasionally unlocking also works. The last thing I find in /var/log/syslog is [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe B FIFO underrun Note: Ubuntu uses kernel version 4.13.0-16-lowlatency for some reason, but the issue also appears when I boot with the generic version.
