            Bug ID: 71531
           Summary: eDP disabled forever if lid closed at boot time
           Product: Drivers
           Version: 2.5
    Kernel Version: 3.12.1
          Hardware: x86-64
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - Intel)
          Assignee: intel-gfx-bugs at lists.freedesktop.org
          Reporter: matthieu.imbert at ens-lyon.fr
                CC: intel-gfx-bugs at lists.freedesktop.org
        Regression: No

On a dell e4310 laptop with arrandale dual-core i5-540m integrated graphics,
driver i915: If the laptop is booted with its lid closed, the eDP is not
initialized at all and is lost forever.

dmesg says: [drm] failed to retrieve link info, disabling eDP

Booting with lid closed is a common situation for anyone using a docking
station: A user puts the laptop closed on the docking station, boots (lid
closed), using external screen. Later, the user needs to move and then undock
the laptop, opens the lid and expects to have the eDP working (X + some desktop
env correctly handle these situations).

This bug occurs with i915 started with option modeset=1 (KMS enabled).

I use the current default debian testing kernel. If needed I can recompile a
specific kernel (possibly patched) for testing.

Feel free to ask for any needed details (logs, anything..)

Matthieu
