startx with "root" and not with "knoppix"

Hi,
i'm creating my knoppix customization with the good "HOWTO: Remaster Knoppix using Fabian Franz's remaster script"

for error, i have login (inside chroot) as root and not as knoppix and launch startx.

after, i'm go out from kde and i try to launch startx as knoppix user but i have this error:

X: cannot stat /tmp/X11-unix (no such file or directory), aborting.
giving up

:cry:

where is the problem? how can i start kde as knoppix user?

thank you!

hopefully i have solved quickly:

i have created a new folder called "tmp" and set read and write

:wink:

bye!
