DirectFB with touchscreen

I was getting a problem with DirectFB and touchscreen. The df_windows example didn’t work correctly it was uncalibrated, the cursor didn’t was showed at pen stylus position.

The problem was caused because DirectFB was just using the Linux Input (/dev/input/event1) instead the tslib device (/dev/input/tslib0) because tslib0 didn’t exist. Then after to calibrate the toochscreen with tslib (ts_calibrate) DirectFB still uncalibrated.

Then to solve this problem I do that:

mknod /dev/input/tslib0

export TSLIB_TSDEVICE=/dev/input/tslib0

rm -f /etc/pointercal



Solved the problem!
