The ELO touchscreen drivers only run on the 32 bit architecture (i386), not the 64-bit. You can install them on a media director that is 32 bit even if the core is 64 bit. Just be sure the architecture for the media director is i386 and not amd64.
To install the ELO touchscreen drivers in LinuxMCE 0710, run this command:
apt-get install elo-touchscreen
and reboot the computer.
The commands for running the calibration utility are:
cd /elo ./elova -u
These must the run under X.
