    Phoronix: Multi-Touch For The X.Org Synaptics Driver

    Takashi Iwai of Novell/SuSE has just published a series of 18 patches for the X.Org Synaptics input driver that primarily provides multi-touch support. There's also some fixes and other changes to this Synaptics driver for X, but the primary feature is the addition of multi-touch support under Linux (and other X.Org-using operating systems) for supported hardware...

    Hmm this leaves me confused. I have an Elantech touchpad, which is supported by the Synaptics driver, and I definitely have multi-touch support since years: double and triple tapping, two-finger scroll, etc.

    Wasn't this supported on Synaptic-proper touchpads? Isn't it the same multi-touch we talk about?

    However as there's already a working multi-touch implementation for Elantech, I don't see what were Novell's patent concerns based on...

        I'm under the impression that newer Synaptics touchpads such as the "Clickpad" use an entirely different mechanism for multi-touch support.

          Does anybody know if the new Pinch feature will work on older touchpads like the 6.x series?

            Has anybody tested it? did anybody assemble a megapatch to apply?

              I've downloaded all the patches and compressed them. Download here: http://www.speedyshare.com/files/246...atches.tar.bz2. All the patches patch successfully using git xf86-input-synaptics, but it won't compile correctly after patching.

                Now we just need to figure out how to enable multitouch on all those touchpads that physically support multitouch, but are merely locked down by the firmware.

                    Admiral0,
                    FWIW I get the same errors with http://aur.archlinux.org/packages.php?ID=38120
                    But it seems to work.
                    Code:
                    (EE) SynPS/2 Synaptics TouchPad no synaptics event device found
                    (EE) Query no Synaptics: 6003C8
                    (EE) SynPS/2 Synaptics TouchPad Unable to query/initialize Synaptics hardware
                    (EE) PreInit failed for input device "SynPS/2 Synaptics TouchPad"
                    However, the multitouch patches causes my pointer to go a bit crazy.
