Bug ID: 191211
Summary: Razer Blade Stealth laptop fails to send lid open on
suspend resume
Product: ACPI
Version: 2.5
Kernel Version: 4.9
Hardware: x86-64
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Power-Sleep-Wake
Assignee: [email protected]
Reporter: [email protected]
Regression: No
The Razer Blade Stealth (2016 Kaby Lake) laptop fails to send lid open on
suspend resume. A work-around is to close-and-reopen the lid a second time
immediately after opening the lid before userspace re-initiates suspend. This
would seem to indicate that the lid open event isn't being sent by the platform
AML (based on my reading of
https://www.kernel.org/doc/Documentation/acpi/acpi-lid.txt). evtest never shows
the open event arriving (unless doing the workaround above):
$ sudo evtest /dev/input/event0
Input driver version is 1.0.1
Input device ID: bus 0x19 vendor 0x0 product 0x5 version 0x0
Input device name: "Lid Switch"
Supported events:
Event type 0 (EV_SYN)
Event type 5 (EV_SW)
Event code 0 (SW_LID) state 1
$ sudo cat /proc/acpi/button/lid/LID0/state
state: closed
This bug will track implementing an in-kernel work-around.
