I am working on a project, in which i have to interface a 21.5’’ touch screen(Dell S2240T) with raspberry pi 2.
I have installed Ubuntu mate 15.10 OS on SD card. The OS is working fine with mouse & keyboard but when i use this system on my touch screen monitor, right click option is not working (on long touch) and i am not able to zoom in, zoom out & scroll using two fingers.
Kindly provide me your valuable suggestions to solve this problem.
