![]() Note that this only changes the behaviour of the touchpad You provided you're running server 1.8 or later. ![]() The following configuration snippet will do that for You need to configure your X server to use the evdev driver for the The synaptics driver doesn't do this, but the evdev driver does. Position of a finger on the touchpad rather than just relative It was discussed back in 2010 on the Xorg mailing list (an excerpt below): The only way I see this to be possible at this moment in Linux is using the evdev driver in Xorg. Joe Shaw, author of the code and only known user doesn't have a use for Little usage of it (I haven't seen bug reports from people claiming to use Moving a touchpad in absolute mode is unusual - touchpads are disconnectedįrom the output device, so direct interaction is hard. The capability of actually putting a Synaptics device in absolute mode in Xorg has been removed recently by this commit in the xf86-input-synaptics driver: Remove absolute mode My Synaptics touchpad reports the absolute positions as follows: Event type 3 (EV_ABS) Test this for yourself using evtest in a virtual terminal (to suspend X). The absolute data is really there, as the driver can detect whether you are touching it at the edges for scrolling for example. Unfortunately, even if you have a touchpad pretty much capable of reporting all absolute values, most touchpad drivers do not let you use them in Linux applications. Some more basic touchpads don't have the capability of reporting the absolute positions.Touchpads capable of both relative and absolute modes needs switching of modes, which is very hardware specific and not application-aware. ![]() A regular application can't talk to the touchpad directly (by design), so you really have to look for a solution in the driver. Touchpads reporting absolute positions data is being translated by the Xorg driver to relative movement for the applications.You won't find a program doing this, because of these three types of touchpads the drivers tries to abstract to a single representation to applications:
