-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 The following refers to the same Touchpad as in bug #15893 (ALPS in an Acer Aspire 532h). The device is recognized as "ImPS/2 Generic Wheel Mouse as /devices/platform/i8042/serio1/input/input5" instead of a touchpad; at least since Linux 3.0 (and up to 3.2-rc2). As one result, middle mouse button emulation doesn't work. IIRC, evdev disabled it for non-touchpad inputs a while ago. Is there a way to have the device recognized correctly as a touchpad (as it used to be a few versions earlier, unfortunately I can't remember which versions worked).
I sent some patches that should be in 3.3 that will get your touchpad working, with the exception of multitouch (the 532h is one of the machines I used to develop the patches). You can find the patches in the following locations if you'd like to give them a try. https://lkml.org/lkml/2011/11/7/433 http://git.kernel.org/?p=linux/kernel/git/dtor/input.git
