can someone help with "thinkpad-acpi" driver questions

SaintDanBert · 12-12-2011, 11:32 AM

First, I have a Thinkpad running Linux Mint-11 with thinkpad-acpi, v0.24. After all of this time, it v0.24 actually the current edition?

My laptop reports:

Code:

prompt$ uname -a

Linux XXXXXX 2.6.38-8-generic #42-Ubuntu SMP 
     Mon Apr 11 03:31:24 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux

and also

Code:

prompt$ modinfo thinkpad-acpi

How does one discover which of the various possible ACPI events are actually deployed by your hardware? I've used acpi_listen without success -- nothing gets displayed -- while I'm tinkering with the various hardware buttons and parts.

I have a very new model Thinkpad X220t "convertible tablet" laptop PC. All of the buttons and parts work with that expensive workstation software so I know the iron works.

Thanks in advance,

These are the results I get when I close the lid, toggle wireless and brightness. Not sure how one uses these tools.
