I suspect your problem is a previously loaded overlay. The X11 connection rejected message is due to some parts of the overlay loading code running via sudo, which can't access the display you have forwarded as via ssh as the LinuxCNC user. The fact that the overlay is failing to load is due to a resource conflict which is probably due to the fact that some other conflicting overlay was loaded first (did you experiment with loading a few different configurations, or have you only tried the one?). There is currently no way to safely unload an overlay, so at this point, I suggest rebooting and trying again. After you reboot, and before trying to run LinuxCNC, try to run xterm to double-check your display forwarding is setup properly. If you get any errors running xterm, get that sorted out before trying to run LinuxCNC. -- Charles Steinkuehler char...@steinkuehler.net
