Had some trouble setting up the TTX touch screen (which uses an eGalax touch sensor). It seemed to be plug and play (it uses USB connection) but the x-axis was flipped. Luckily I found this handy post:

Short instructions:
- edit /usr/share/hal/fdi/policy/20thirdparty/50-eGalax.fdi and add a “merge key” line with the others like this:
<merge key=”input.x11_options.SwapX” type=”string”>1</merge> - run Administrator -> Calibrate Touchscreen
- hit Enter, then tap the X’s, but swap the left and right. That is, tap them in this order:
- top right
- top center
- top left
- middle right
- middle center
- middle left
- bottom right
- bottom center
- bottom left
- Restart and it should work!
