Thanks Robert. I can be patient. I just needed to know if this is a known issue and if it was fixable with a configuration file or install program. I would be happy to help if I can, but I am not that familiar with kernel code. I am experienced in C, C++, C#, Java. -- For more options, visit

I think William is right about developing natively on the beaglebone. The GUI design could be done from other desktop and copied to BBB, or done natively. So are the cpp files (if you are using C++, I don't know how to do other languages like Python or bonescript). But all the program files (to me
