Tpctl

The tpctl user-space tool, in conjunction with the thinkpad kernel module, provide access to SMAPI functions on ThinkPads. It provides rich functionality for older ThinkPads, but on newer ThinkPads much of this functionality is exposed and supported through an ACPI interface and the SMAPI access does not work anymore. Other models are supported by tp_smapi.

Kernel 2.6.9 and newer is unsupported (patch needed); for kernel 2.6.3 and newer you need tpctl >=4.14 and thinkpad >=5.5. For details, see the README and list of supported models.

• Project page: http://tpctl.sourceforge.net/
• You need to download the thinkpad module and tpctl userspace tool.
• There is also an optional GUI: configure-thinkpad.
