The KMilo Thinkpad Plugin software enables users to utilize the special buttons on IBM Thinkpad keyboards for volume control, muting, brightness adjustment, and more.
One particularly useful KMilo plugin is designed to read the nvram used in IBM Thinkpads. To use it, you'll need the Linux nvram module and to create a device node. If you have a Thinkpad R30/R31 model, you'll be pleased to know that the plugin is essential for software volume control, as these models lack any hardware volume control.
Of course, other models can also benefit from software volume control, especially if you want a volume change step different from the default value of 14. However, this feature does require write access to nvram, meaning you'll need to make sure that it's safe to use with your machine before turning it on.
To configure KMilo further, there's a KControl Centre module included with the software. Among other things, this module lets you decide whether or not to run this service by default, giving you complete control over how you want to use KMilo. Overall, this is a great program for anyone who wants to get the most out of their keyboard or laptop.
