"Multi-Touch For The X.Org Synaptics Driver

Posted by Michael Larabel on October 08, 2010

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.

It turns out that Takashi actually wrote these patches some months
ago, but that Novell's legal department didn't allow him to publish
the code for upstream integration over concerns of possible patent
infringements. This was mentioned on the mailing list.

However, after this work was independently discovered, Takashi has now
went ahead and mailed out the patches for hopeful integration."
