Looking for model touch glass which has the following qualities:
1. Support by the linux kernel. Installing proprietary drivers is not encouraged.
2. Support multitouch from two touches, and more.
Also interested in support for multi-touch in linux in General. By manufacturers(e.g. 3M) argue that currently linux does not support multi-touch, and applications that can work with that.
Digging in the kernel sources assume that the kernels 3.2+ has support for hid-multitouch, and in theory most of the market devices will work out of the box. But it is interested in the successful launch, not to buy a useless piece of metal.
I really hope that someone has experience with such devices under linux.
