The UltraNav driver from IBM is based on the Synaptics driver. If you wish to disable the touchpad, you can do so in the BIOS, or on modern HAL-enabled distributions, create a file /etc/hal/fdi/policy/disable-touchpad.fdi To enable TrackPoint scrolling and use the ALPS touchpad, apply following patch:, which has been merged into the main kernel 2.6.31-rc1. Currently, the only choice to configure the TrackPoint to scroll properly with middle button pressed is to use the generic "mouse" driver in X.Org OR apply the tiny patch posted to bugzilla and configure the touchpad as Synaptics (but this breaks TrackPoint scrolling). This leads to some problems since ALPS refuses to provide specifications on how exactly is the TrackPoint is separated from touchpad. Some ThinkPads (at least some of the R61 models) has an ALPS dual pointing device (instead of Synaptics). The touchpad features several customizable features, including scrolling by movement along the edges, tap zones, and ignoring accidental touches/palm rejection.īoth the TrackPoint and the TouchPad (UltraNav) work with the standard ps2 mouse driver of Linux kernels.įor advanced configuration of the touchpad, see the Synaptics TouchPad driver for X page. The technology for this combined pointing device comes from either Synaptics, ALPS, or ELAN.
Starting with the T30 onward, IBM introduced the UltraNav, a combination of both the traditional TrackPoint coupled with a programmable touchpad.
The classic integrated pointing device in a ThinkPad was always a TrackPoint.
