Created attachment 127581 [details] dmesg with drm.debug=14 with and without error and i915_vbt I'm testing a Baytrail device with mipi/dsi display and hdmi output. When I boot without the hdmi connected the mipi/dsi works OK and after connecting the hdmi both mipi/dsi and hdmi display graphics OK. (attached dmesg-mipi-ok.txt) If I boot with the hdmi connected it's selected by the bios as the default display, Ubuntu only boots in hdmi and it works OK in this display but MIPI/DSI is black. It's listed as connected by xrandr but I can't reset in any way.(attached dmesg-mipi-error.txt) I'm using Ubuntu 16.10 with kernel 4.8.4 Also attached /sys/kernel/debug/dri/0/i915_vbt in zip BR.
