USB booting :: cannot boot anymore

Hi guys

since I installed my 1.5 copy of dsl to usb (dragging over the knoppix folder to usb pen, and booting from floppy as I used to do with 1.4) I cannot boot anymore.
I get these messages:
usr/sbin/xsetup.sh: line 60 /home/dsl/.xserverrc permission denied
chmod /home/dsl/.xserverrc no such file or directory
touch /home/dsl/.xvesadefault permission denied
Xauth timeout in locking authority file /home/dsl/.xauthority
(this was a message I used to get even before, but then system booted normally)

xinit: no such file. or directory
no server /home/dsl/.xserverrc in PATH

what do these messages mean? anyone experienced the same problem?

thanx
