I run it with this command : " xinit ./filename"
do I use right command ?
then after run have this error :" Fatal server error:
Server is already active for display 0
If this server is no longer running, remove /tmp/.X0-lock
and start again."

So you're running "./filename" from the command line. How did you get to it? Via ssh, booting to console or opening a terminal in the desktop?

If the last of these, try running "./filename" rather than "xinit ./filename" as the X server is already running.
