An update to this thread. I found this thread in Odroid's forum http://forum.odroid.com/viewtopic.php?f=79&t=5650 and followed the suggestion of the fourth post, saying to change the 'Option "fbdev" "/dev/fb1"' to fb0 (well it's for Debian Wheezy and my Odroid is running in Ubuntu, but gave it a shot), and when I try to open Pd I get this: xcb_connection_has_error() returned true priority 6 scheduling enabled. priority 8 scheduling enabled. application-specific initialization failed: couldn't connect to display "localhost:10.0"
but I don't get the "X11 connection rejected because of wrong authentication." error any more. Then watchdog is signaling Pd without Pd opening. Is this any better?

I'm starting a new thread cause the problems I have with Odroid are changing. Since I installed Pd with apt-get, at first, when I was writing /usr/bin/pd, I was getting the following: priority 6 scheduling enabled. priority 8 scheduling enabled.
whenever I have problems starting Pd, I start with disabling (default) options. the above indicates that Pd tries to run with rt-priviliges. run with "-nrt".
Fontconfig warning: ignoring UTF-8: not a valid region tag
and Pd was hanging (this was mentioned in the previous thread).
Now I get something else when I try to open Pd, which is this:
[...]
xcb_connection_has_error() returned true
since i have never seen this error before, i pasted it into my favourite search engine (you might want to do the same). the results i got seem to indicate that it is related to pulseaudio.
I am searching the errors, but get dozens of links and not sure which one gives answers I need. I try different things...
try starting Pd without audio: run with "-nosound".
Did with both -nrt and -nosound flags, but the same thing happens, only I didn't see watchdog signaling Pd...

again i did a quick websearch, and found [2], which gives a nice checklist (though you can ignore the last item with "X11 client forwarding", as this is a) turned on explicitely with "-X" and b) seems to work anyhow e.g. on udoo)
Seems to be ok, following these directions. Though, since the initial problem was space, I searched for the linux command to show partitions and found $ sudo fdisk -l, which gives the following: Disk /dev/mmcblk0: 7818 MB, 7818182656 bytes 4 heads, 16 sectors/track, 238592 cylinders, total 15269888 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000c4046

any secret hidden there?
priority 6 scheduling enabled. priority 8 scheduling enabled. X11 connection rejected because of wrong authentication. X11 connection rejected because of wrong authentication. application-specific initialization failed: couldn't connect to display "localhost:10.0"
"localhost:10.0" is the DISPLAY-setting for X11-forwarding via ssh. this means: whenever you start "ssh -X ...", ssh will set the DISPLAY to this value, so that all X11-applications will be forwarded to your local machine.
in any case, you should first get X11 forwarding to run properly (without Pd). use some simple application (like xclock or xeyes) to test whether it works,
Nope, none of them. Both give this error:
X11 connection rejected because of wrong authentication. Error: Can't open display: localhost:10.0
