LinuxCNC works on SSH X but don't start on startx was created by knorst
Hello
I've installed a debian image with Xenomai kernel on a RPi and setup the LinuxCNC.
If I run from a ssh -X terminal works, but if I try to run from startx direct from RPi I receive this log error.
Any suggest to fix?
Follow the log error, the subsequent debug errors are consequence from rtapi_app_xenomai fault:

Hi
You seem to be running a Xenomai kernel and an old Linuxcnc 2.6 by the look of it.
I think this may be one of Charles's old images, it might even come from the UBC3 testing era
before the fork into Machinekit
You need to go to the Machinekit forum, Linuxcnc does not support Xenomai or ARM processors in any of its branches any more
There are much newer rPi xenomai images available there
groups.google.com/forum/#!forum/machinekit
In this instance I can assist with the error, the cause of the error is in the log
Even if you build as root, it will not run with a root user.
(unless you modify the code, but I won't go into that)
regards

Hello
Thanks for the reply, actually the problem was much more "noob"... I was starting the startx with root permissions...
Sometimes a sudo it's hard to find hehehhe
It's working right now.
About the iso, I just pickup one to test the funcionality. Actually I have an UDOO quadcore that I want to use with the LinuxCNC.
Btw, I'll update this rasp image with a newer one.
