Make Your Docking Station Work for You (on FreeBSD)

- Here's the problem. I have a Dell Latitude E-series laptop running FreeBSD - 12.1-RELEASE. I also have a Dell E-Port II docking station on my desk.

Sleeping on Lid Close Except When Docked

+ +

+ This is an easy one. You can use sysctl to configure what happens + when a laptop lid is closed. I wanted the lid closing while undocked to + suspend (put the laptop to sleep). When it's docked however, I don't use the + internal display and wanted to be able to shut the lid and leave it shut. If you read ACPI(4) in the manual, you'll find this little passage: +

+ +
+

+hw.acpi.lid_switch_state
+		 Suspend state (S1-S5) to enter when the lid switch (i.e., a
+		 notebook screen) is closed.  Default is "NONE" (do nothing).
+

+
+
+
I changed this value a long time ago so closing the lid suspends the laptop. You can check with sysctl:

+
+
+
+$ sysctl hw.acpi.lid_switch_state
+hw.acpi.lid_switch_state: S3
+
+

+
+
Now, if I wanted to disable this functionality, I would just change this parameter as root:

+
+
+
+$ doas sysctl hw.acpi.lid_switch_state=NONE
+hw.acpi.lid_switch_state: NONE -> NONE
+
+

+
+This change takes effect immediately. I can open and close the lid and nothing happens but turning off the screen. Awesome.
