On devices such as the Thinkpad X250, the clickpad can be pressed to generate mouse button events 1 and 2. There are also additional physical buttons which the pms(4) driver recognizes as "up/down" buttons (mouse buttons 3 and 4). Allow these to be remapped to buttons 1 and 2 and used like normal touchpad buttons with the following sysctl: # sysctl -w hw.synaptics.up_down_emulation=3 While here, adjust the existing "middle button emulation" (hw.synaptics.up_down_emulation=1) so it works with single-button clickpads. XXX: 3 may be a more useful default than the current default, depending on hardware availability of touchpads with "up/down buttons". Update the documentation accordingly. |
