Subject: i915: black screen after blank when LID is closed on Linux >= 3.1
Hi,
since Linux 3.1 I'm having some problems with i915 driver on HP nc6120
with 915GM chipset. The display goes black after the kernel tries to
blank screen while LID is closed (see steps to reproduce to more detailed
description).
Currently I'm using Linux 3.7-rc6 with KMS enabled and disabled ACPI
video by something equivalent to (without it the LID, and the whole
ACPI, does not work):
diff --git a/drivers/acpi/video.c b/drivers/acpi/video.c

if (register_count) {
/*
* if the function of acpi_video_register is already called,
I also tested this kernel with merged
git://people.freedesktop.org/~danvet/drm-intel drm-intel-next.
Steps to reproduce:
1. $ setterm -blank 1
2. close LID
3. sleep 90
4. open LID
5. press key
6. close LID
nothing happens here, the screen is still turned on, should be turned off
7. open LID
backlight is on, but screen is black, but some artifacts are visible so
LCD is probably turned off, and the display is not usable anymore
I have bisected this problem and it's introduced by commit
120eced9efe7fdb5123db4ea47e9adee9b66284e
(drm/i915: Set crtc DPMS mode to ON in intel_crtc_mode_set).
In Linux 3.1 to 3.6 I've been using following workaround:
