Hi everyone,
after having installed the debian distro. i noticed that there is no
right mouse button. so many "standard" applications aren't usable
because they depend on it(i tried to add an applet to my xfce panel..).
so i created a patch to the xorg tslib input driver. once installed you
can press the aux button on your openmoko and than tap on the screen and
i will be recognized as right button click. i attached the patch but i
hope that it will be included in the standard package so everyone have
not to compile is by them self.
