I am using KDM. `journalctl _SYSTEMD_UNIT=kdm.service`    did not output any
log entries. And in /var/log/kdm.log there is not anything interesting.  Not
sure where the stderr of kdm and its childs go to... I will try without kdm:


With a pure startx 2> stderr.log (no kdm not enabled in systemd) and a exec
xterm X crashes on the 
third re-entry of the mouse cursor. Content generated by the crash:

> xterm: xinit: connection to X server lost
> fatal IO error 11 (Die Ressource ist zur Zeit nicht verfügbar) or KillClient on X server ":0"

With lxde instead of xterm it even crashes at the first reappear of the mouse
cursor:

> XIO:  fatal IO error 11 (Resource temporarily unavailable) on X server ":0"
>       after 31 requests (31 known processed) with 0 events remaining.
> xinit: connection to X server lost
> 
> waiting for X server to shut down XIO:  fatal IO error 11 (Die Ressource ist zur Zeit nicht 
> verfügbar) on X server ":0"
>       after 3514 requests (3511 known processed) with 0 events remaining.
> pcmanfm: Fatal IO error 11 (Die Ressource ist zur Zeit nicht verfügbar) on X server :0.

By the way, X does not "restart" (as I first wrote in the bug title) when not
using KDM. Apparently the restarting is a feature of KDM. Being just on tty1
with startx it crashes and makes the computer not respond to any input.
Accessing by ssh (and rebooting) works.

However, I guess those stderrs are not really useful for you. Please tell me
how to investigate better.
