It works ok. accensi@ACC-MacBookAir:~$ xrandr -q Screen 0: minimum 320 x 200, current 3286 x 1080, maximum 32767 x 32767 eDP1 connected 1366x768+0+0 (normal left inverted right x axis y axis) 256mm x 144mm 1366x768 60.0*+ 1360x768 59.8 60.0 1024x768 60.0 800x600 60.3 56.2 640x480 59.9 VGA1 disconnected (normal left inverted right x axis y axis) HDMI1 disconnected (normal left inverted right x axis y axis) DP1 connected 1920x1080+1366+0 (normal left inverted right x axis y axis) 477mm x 268mm 1920x1080 60.0*+ 1680x1050 60.0 1280x1024 75.0 60.0 1152x864 75.0 1024x768 75.1 60.0 800x600 75.0 60.3 640x480 75.0 60.0 720x400 70.1 HDMI2 disconnected (normal left inverted right x axis y axis) DP2 disconnected (normal left inverted right x axis y axis) VIRTUAL1 disconnected (normal left inverted right x axis y axis) DisplayPort is detected and there is no messages like "[drm:intel_dp_i2c_aux_ch] *ERROR* too many retries, giving up" Probably 3.11.4 would work too, as upstream DRM changes related to error message above were applied on it: drm/i915/dp: increase i2c-over-aux retry interval on AUX DEFER Will complete other tests (on boot, after suspend, after hibernate, etc).
