<pre>Well, this issue is not related to libinput but to the use of acpi_lid_open()
by the intel i915 driver (in drivers/gpu/drm/i915/intel_lvds.c).
It has been shown that on some platforms the ACPI _LID call is not reliable and
only the closed event is sent.
drivers/gpu/drm/i915/intel_lvds.c ignores the value provided by the lid
notifier (unsigned long val parameter), and does it's own call to
acpi_lid_open().
IMO, we should either enforce i915 to use the provided value (as sent by Lv in
<a href="https://patchwork.kernel.org/patch/9713021/">https://patchwork.kernel.org/patch/9713021/</a>), or make sure acpi_lid_open()
returns the fixed value (so no change from the i915 driver would be required).</pre>
