I worked on this problem/something similar a while ago... My touch screen was detected as a linux_input device and instead of trying to get tslib working, I simply scaled and fixed the offset for my min/max and made the variables available in the directfbrc file. See my old post: http://mail.directfb.org/pipermail/directfb-dev/2009-January/004788.html I realized just recently that detecting a descent min/max x/y should be done with a normalize distribution of values instead of one-time min/max as there may be an occasional value which is really out of the normal range (think about approaching the edge of a resistive screen mounted inside a panel which covers .1" on the edge of the screen).. Hope it helps, - Azilat _______________________________________________ directfb-dev mailing list directfb-dev@directfb.org http://mail.directfb.org/cgi-bin/mailman/listinfo/directfb-dev
