Multi Touch now Supported by Linux Kernel
A development group at ENAC in Toulouse, France, reports that it has developed a proof of concept for adding iPhone-like multi-touch support to the Linux kernel. The group has released a video showing multi-touch effects such as resizing and rotating using Linux 2.6.30. In an email, Boulabiar stressed that the code is different than the Multi-Pointer X (MPX) technology being integrated into version 7.5 of the mainline X.Org server. Whereas MPX is a modification to X Window that provides multiple independent pointers (mouse cursors) at the windowing system level for multi-pointer capability, the ENAC code offers true native multi-touch capability, says Boulabiar. "The video shows multitouch effects that are being supported natively to send ABS_MT_* events from the kernel," wrote Boulabiar. "When making the demos, I have chosen to use general libraries not related to a WM, to be able to run demos on any Linux platform." Boulabiar added that he expects the technology ...
