Dell S2240T multi-touch monitor on Linux - has anyone tried it?

Question

linux

Need a touch monitor to work in Linux. The Dell S2240T model looks very interesting, but I could not find information about what kind of sensor it is and whether it works in Linux. Google and Dell didn't help. Has anyone here used this monitor in Linux, or at least can tell the USB ID of the sensor installed in it?

Answer 1

After receiving the monitor, I connected it to a working computer with Kubuntu 13.04. The sensor was identified immediately. Unfortunately, out of the box, KDE doesn't support touch very well. However, I was interested in the ability to work with touch and gestures from a Qt program. Here the situation is as follows: Qt from the repository (4.8.4 and 5.0.1) sees all 10 touch points and gestures work. But the Qt binaries from the qt-project site do not support touch, neither 5.0.2 nor 5.1.0 - I had to rebuild. Thus, for development, this monitor suits me.
But for use, I would not recommend it: the sensor is very slow. When moving quickly from corner to corner, the cursor sometimes lagged behind a quarter of the screen. Moreover, the problem was observed not only in Linux, but also in Windows 7.

Answer 2

I managed to poke this monitor a little in Flash (by the way, thanks to them for specially bringing the monitor from the warehouse). The sensor works by itself, so I only connected via USB. There is CoolTouch ™ from Advanced Silicon SA, USB ID 2149:2122. Linux is defined and sends multitouch events.

Answer 3

Thanks for the reports.
I also want to buy one for the Media Center on CentoOS
