How to reverse the axis of touch screen calibration

Mon Oct 21, 2013 4:40 pm

My touchscreen appears to have the axis reversed, ie, if i move right the house move left. The xinput-calibrator cannot fix this issue. Is there a way to rectify this in a config file without having to tamper with the kernel drivers?

I tried that "SwapAxes" thing. With the newest raspbian as well. But doesn't seem to have any effect. My touch screen is a lilliput device. Maybe it's different in some way?

So I finally got it to work. The lilliput device is actually recognised as a tablet device rather than a touch screen. So http://www.raspberrypi.org/phpBB3/viewt ... 62#p425962 gives the right solution but instead of editing the touchscreen section, edit the tablet section
