Enable both mouse and touchscreen

can anyone tell me how to enable the mouse(/dev/input/mice) and
touchscreen(dev/input/event0) while running an application before Qutopia??

The keywords are "environment variables".

These can be set in a script that is run during init.  The only example I
can point to is the /etc/profile.environment file in the Pengutronix BSP.  

/etc/profile appears to call this file, but I don't see what runs
/etc/profile  

Good luck!

A shell (/bin/sh) reads in the "/etc/profile" when it is started as a
"login shell" (refer "man sh").
That is why sometimes scripts must source "/etc/profile" by themselfs
because their shell is no login shell (when started from startup scripts in
"/etc/init.d" for example)

Thank you.  Found this:
