Bug ID: 195455
Summary: Regression: Notebook display enabled despite closed
lid and external displays
Product: ACPI
Version: 2.5
Kernel Version: 4.10.11
Hardware: Intel
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Other
Assignee: [email protected]
Reporter: [email protected]
Regression: No
I'm using an HP EliteBook 840 G1 attached to a docking station with two
external monitors. The notebook lid is closed, I only use the external
monitors.
When I boot my notebook with Linux 4.10.9 then everything is working fine: The
the two external monitors are automatically used as "Primary" + "Secondary" and
the built-in display is shown as "LID Closed" in the Gnome Display settings.
But when I boot my notebook with Linux 4.10.10+ then the built-in display is
used, too (in addition to the two external monitors) although its lid is
closed.
I can workaround this issue by using "button.lid_init_state=method" and thereby
essentially reverting the 4.10.10 commit
8d5dd97f55563634ad830ea47c709bc96606ad65 (upstream commit
77e9a4aa9de10cc1418bf9a892366988802a8025).
Is this intended behaviour?
I'm using Gentoo Linux with Systemd 233, X.Org 1.19.3 and Gnome 3.22.2.
