connection to X server lost

[parrotface]

Running BT5 KDE 32 on USB stick in eeepc.
I keep getting connection to X server lost and have to do startx again to get going.
Can't pin it down to any action but the latest time was when I inserted a SDHC card and Dolphin auto loaded and server crashed. I will try and monitor further instances.

Next time it crashes, in tty1 please try: tail /var/log/syslog
and look for anything wierd (or post the result here)..
