The touchscreen on mine is the eGalax which is a common touch screen controller. \r\n\r\nThe touchscreen took a while to sort out but it works perfectly now. You will probably need to use the min/max_abs_x/y parameters in the [input] section of.kivy/config.ini and there is a bug you need to patch before kivy will use them. The eGalax reports absolute co-ordinates which is why you need them.\r\n\r\nA very useful utility to install is evtest which is a command line program which will stream the touch screen values continuously and, by touching the corners etc, will indicate the values that your screen is generating.  The evtest output is then used to set the values in \r\n\r\nYou may need to update the tslib for eGalax as earlier code didn't recognise it.\r\n\r\nThe screen was also a PITA and I had to try a number of settings before I got the settings that matched the screen (800x600 in my case).  The various utilities that report the screen capabilities didn't help much as the screen didn't report correctly. In the end it was the HDMI settings in Rpi config.txt that nailed it for me.  After trying many combinations, I eventually set the hdmi_group and hdmi_mode specifically to the mode I wanted and voila! \r\n\r\nI am using Jessie with Kivy 1.9.1. \r\n\r\nIn conclusion, I'm sure the screen you are considering should work with Rpi.\r\n"}}
