[gentoo-user] [OT] XNest and embedded system: Kaboom! (sometimes)

[meino.cramer@gmx.de]

Hi,

I want to display the X-display of my embedded Linux system (a
Beaglebone black) on my PC.

For that I started XNest on display 1 on my PC (option: -ac) and
set DISPLAY on the embedded system (running an XServer also)
accordingly.

I could run openbox, urxvt, gnumeric, tgif (for example) via
this setup nicely.

But when I started hatari (an AtariST-Emulator) on the embedded
system, XNest on the PC stops running/crashes.

Running hatari on the XServer of the embedded system runs nicely
though.

On the X-point-of-view hatari should be nothing else but "just another 
X application"...or?

The output of XNest after such "sudden stop" is:

homepc:/home/user>Xnest -ac :1
    _XSERVTransSocketOpenCOTSServer: Unable to open socket for inet6
_XSERVTransOpen: transport open failed for inet6/homepc:1
_XSERVTransMakeAllCOTSServerListeners: failed to open listener for inet6

What went wrong here?
How can I fix it?


Thank you very much in advance for any help!
