Drivers

This page holds a model independent Linux driver matrix for ThinkPads. At current state it only consists of drivers which are maintained outside the Linux kernel source tree (even though they might be included in actual kernels already). For more specific information regarding your particular ThinkPad see the individual Components of your Model. We also have an alphabetical listing of drivers.
