Personally, I'd recommend going with Ubuntu. The community's larger, there's support for more stuff (drivers etc.) in Linux, they're geared more toward newbies who don't know much about Linux/UNIX.

That's just my own unscientific opinion. Take it from a 48-year-old who's been using UNIX since BSD4.1 (...ehm, around 1983).

GETUID(2)						     Linux Programmer's Manual							 GETUID(2)

NAME

       getuid, geteuid - get user identity

SYNOPSIS

       #include <unistd.h>
       #include <sys/types.h>

       uid_t getuid(void);
       uid_t geteuid(void);

DESCRIPTION

       getuid() returns the real user ID of the calling process.

       geteuid() returns the effective user ID of the calling process.

ERRORS

       These functions are always successful.

CONFORMING TO

       POSIX.1-2001, POSIX.1-2008, 4.3BSD.

NOTES

   History
       In UNIX V6 the getuid() call returned (euid << 8) + uid.  UNIX V7 introduced separate calls getuid() and geteuid().

       The  original  Linux  getuid()  and  geteuid()  system  calls supported only 16-bit user IDs.  Subsequently, Linux 2.4 added getuid32() and
       geteuid32(), supporting 32-bit IDs.  The glibc getuid() and geteuid() wrapper functions transparently deal with the variations across  ker-
       nel versions.
