hi all:
*
*** is there any difference between "/usr/bin/X" and "/usr/bin/Xorg"? On my debian box, /usr/bin/X is not symlink to /usr/bin/Xorg, and i can start X server with /usr/bin/X but fail with /usr/bin/Xorg? i google it but find nothing, could any one here help me? thanks in advance.

wow - i'm disappointed no one's ever answered this... i too would like to know:
root:~/# ls -o /usr/bin/X*
-rwsr-sr-x 1 root 9232 Dec 16 2011 /usr/bin/X
-rwxr-xr-x 1 root 1889472 Oct 29 2011 /usr/bin/Xorg

both files are ELF executables, and they are CLEARLY different.
so what exactly IS the difference btn them???

TIA...

In the beginning was MIT's The X Window System. The main server is
'X' as in /usr/bin/X. This was rewritten for the 80386 as Xfree86
with the same names. Later through much controversy the Xfree86
license was changed to be restrictive in 2009. This license change
caused a forking of the previouly available free version of the code
over to a new code base with X.org. The X.org version implements the
new X.org server as /usr/bin/Xorg but maintains /usr/bin/X as a
compatibility layer so as not to break traditional legacy programs
which call the server by the previous name. So at this time
/usr/bin/X is a thin wrapper for compatibility. I believe it simply
turns around can calls /usr/bin/Xorg but perhaps with a very small
amount of option processing if any in between. I don't know. I
haven't looked at the source code. But the "X -help" is identical to
the "Xorg -help" output.
