From dmesg: [ 0.728803] i915 0000:00:02.0: Direct firmware load for i915/skl_dmc_ver1.bin failed with error -2 [ 0.728817] [drm:i915_firmware_load_error_print [i915]] *ERROR* failed to load firmware i915/skl_dmc_ver1.bin (0) This means the GPU can't enter its lowest available power states, plus many display hotplugging scenarios (that only the skl_dmc firmware can handle) are broken. On a whim I tried some other firmware versions: 1) pointed the skl_dmc_ver1.bin symlink to skl_dmc_ver1_18.bin (instead of skl_dmc_ver1_19.bin) 2) downloaded the latest (skl_dmc_ver1_21.bin) and pointed the skl_dmc_ver1.bin symlink to it But neither corrected the situation. Thanks!
