Ubuntu 14.04 multi touch screen support

This is not a problem with "multitouch", it is a problem with "touch".

Before the 14.04 update, the touchscreen was interpreted as another mouse. After the update it is not, but unfortunately Chromium is not reporting touch-events. This means that no graphical web app can be used with Ubuntu on a touch screen.

I managed to make it work on my computer by starting Chromium with the command:

chromium-browser --touch-events=enabled

I just got myself a laptop with a touch screen and have been thinking the same thing. I haven't tried it myself yet,but I just found this: https://wiki.ubuntu.com/Multitouch

Three fingers seems to be the answer, instead of two for zoom and stuff.

You might be able to use Ginn to setup your own multitouch actions: https://wiki.ubuntu.com/Multitouch/Ginn
