Hello Friends,

​

I use FreeBSD 13-RELEASE-p4 on a thinkpad Lenovo X280 most of the time
with a dock station. I use a HDMI external display.

​

I would like :

\- when the laptop is on the dock, close the lid and still have OS
running on the external display;

\- when the laptop is unplugged form the dock the laptop goes to
suspend/resume state (acpi\_state=S3).

​

Did somebody have a trick or a pointer to do that ?

​

Thanks for reading me and for your advises.

Hello, is all the thinkpad hardware detected by freebsd? How is the
battery life?

I'm away from my desk at the moment, but I think for #1, there is a
`lid_state` that you might be able to modify.

\#2 I'm not sure - I've never had a dock.

You might be able to do some of this with `devd`. You can set scripts
to run on various triggers, like lid state. I did something with it
for my brightness buttons, since they weren't exposed to Xorg:

Interesting… I was pretty that \`devd\` could be the trick. Your post
give me some ways.. Thanks.
