i just found out what triggers the xserver to automatically restart:
If you have a look into
/etc/upstart/x_monitor.conf
you can see that the first line is responsible to start the lxinit in case of a crash. So if you are annoyed by frequent xorg resets -> uncomment it
I also played around with the X11 forwarding this morning. Parallel to the xforwarding on the kindle I run a synergy client on the arch chroot and the server on my laptop. (Synergy sends mouse and keyboard to a remote host).
This way I can use the touch of the pw as well as my mouse and keyboard =)
