Thinkpad acpi buttons HOWTO (was Re: [ltp] IBM Thinkpad T23 with Kernel 2.6.8.1)

Sun, 19 Dec 2004 09:56:26 -0500

It's not an insult, it's a valid criticism...there's a big difference.
It may piss you off, but it should help you realize how best to get help
from us in the future. Ask anyone on any mailing list how they feel when
people post questions like yours...you'll likely get the same response.

If you had told us what you had tried, what didn't work and where you
were stuck, you'd have gotten a lot more help than asking "how to set up
ACPI buttons for sleep."

tpctl will let you suspend/hibernate from the command line. However, if
you want to set up your Fn-Fx buttons to sleep, suspend, etc. what you
need is ibm_acpi and acpid as described in the readme I sent to you.  If
you have trouble with it, feel free to post a question, we're always
happy to help with specific questions.
