[sdetweil]

@jefftse do u have a real display

[jefftse]

@sdetweil yes, in fact, i had it all working yesterday till I accident broken my sd card. I had to rebuild everything today.

[sdetweil]

@jefftse did u use my install script? can’t understand why u are having trouble

[jefftse]

@sdetweil sure did. I had to create an user to run your script since it wouldn’t allow me to do in root

[sdetweil]

@jefftse not supposed to be root
are u trying to run as root?

can’t do that

[jefftse]

@sdetweil correct, and I created an user for the install. the install went fine. I just can’t run it!

[sdetweil]

@jefftse I don’t understand created a user.
raspian installs and starts with user pi
