When I dock my thinkpad x270 [1] and run xrandr --auto, image correctly appears on external display. After undocking and docking again, the image on external display doesn't appear any more, and this pops up in dmesg [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe B FIFO underrun After restarting X (no need to reboot), I am able to dock again and get image on external display. I don't think this is a regression, I tried a few older kernels up to something around 4.11, and nothing worked. In case any more information is needed to debug this, please let me know, I'll happily provide it.
