Thanks for your help and easy to follow guide. I got it working, but at this step
pi@raspberrypi ~ $ sudo sh -c ‘echo “sudo /bin/sh /etc/X11/Xsession.d/xinput_calibrator_pointercal.sh” >> /etc/xdg/lxsession/LXDE/autostart’
it said Permission Denied. I made sure to copy it with the quotes exactly. Either frame, on the next step, it started X Windows on the PiScreen. But, I keep getting this error: http://i.imgur.com/4944UXL.jpg?1 even after rebooting. I haven’t set it to auto start on the piscreen just yet. Is this fixable?
Also, I was wondering two things:
1) Is there a way to easily switch back to HDMI from the PiScreen?
2) Is there a way to fit the desktop better to the PiScreen? Maybe like a bit zoomed out than it is now. As you can see in the screenshot with the error here http://i.imgur.com/4944UXL.jpg?1 , there are only about 6 icons on the screen, whereas through HDMI I see my entire desktop with about 10 icons. Even the Minecraft icon is off the screen at the bottom. Or possible a way to scroll around the screen to see more of it?
