Hello,

the best wishes to all for 2013.

Trying the setup from
http://wiki.linuxcnc.org/cgi-bin/wiki.pl?BeagleboneDevsetup
I have to add a file

$ cat /etc/gdm/custom.conf 
[security]
DisallowTCP=false

(see http://ubuntuforums.org/showthread.php?t=1755126)

and changed (as described)

$ cat /etc/X11/xinit/xserverrc 
#!/bin/sh
#exec /usr/bin/X -nolisten tcp "$@"
exec /usr/bin/X  "$@"

on Ubuntu 12.04 to be able to run linuxcnc with
the window on the Xserver of my desktop box.

Thanks to KAR for the explanations in the wiki.

I have also observed the crashes after about 5min.
But after several reboots I was able to run
the cnc demo programm from sim/axis/axis_mm.

After quitting linuxcnc my Xserver hangs. Rebooting
shows, that the beaglebone is still running and I can
start linuxcnc again.

To conect to the beaglebone 
over the serial line I need A:
sudo chmod a+rw /dev/ttyUSB*
