Created attachment 85601 [details] dmesg: VGA detected without been plugged Environment: -------------------- Kernel: (drm-intel-nightly)da66146425c3136943452988afd3d64cd551da58 Author: Mika Kuoppala <mika.kuoppala@linux.intel.com> Date: Fri Sep 6 16:03:28 2013 +0300 drm/i915: include hangcheck action and score in error_state lspci: -------------------- 00:02.0 VGA compatible controller: Intel Corporation Device 0162 (rev 09) Test Steps: -------------------- 1. Only with eDP plugged on machine 2. xinit & , xrandr: Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 32767 x 32767 eDP1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 282mm x 165mm 1920x1080 60.0*+ 1400x1050 60.0 1280x1024 60.0 1280x960 60.0 1024x768 60.0 800x600 60.3 56.2 640x480 59.9 VGA1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 1024x768 60.0* 800x600 60.3 56.2 848x480 60.0 640x480 59.9 Description: --------------------- In our opinion, xrandr can only detect the plugged display pipe, but Baytrail machine can print VGA information without been plugged. Add command "video=VGA-1:d" in grub, we can disable VGA and xrandr will display correctly. Both 32bit and 64bit machine reproduceable. This issue exists on older kernels, it's not a regression.
If we only plugged VGA, xrandr also output both VGA and eDP pipe information.
Should be fixed with commit 6c4a8962a4a078cacfc8eb5d4bd79f6343b8cd7a Author: Jesse Barnes <jbarnes@virtuousgeek.org> Date: Tue Sep 10 14:54:42 2013 -0700 drm/i915/vlv: re-enable hotplug detect based probing on VLV/BYT

I will file new bugs and paste the link here to track.
