Spark installed, but after ./starter nothing happens_Linux

I found the following tip to install Spark on a Linux system:

tar -xzf spark_2_5_8.tar.gz
cd Spark
./starter

the command tar -xzf spark_2_5_8.tar.gz seemed to have functioned and installed lots of directories and files under /home/me/Desktop, starting with a directory named Spark, containing 9 directories and 3 files.

ls
bin documentation jre lib logs plugins resources Spark starter xtra

I then typed ./starter

and nothing graphical happened.

The command ps -AF|grep spark results in
root 32133 31727 0 751 760 0 20:31 pts/1 00:00:00 grep spark

but I see nothing, no Spark client. On the desktop, there is a new folder Spark, with a padlock.

O/S is Ubuntu 8.04 and OpenFire 3.5.2 is running on the box already.

I see no Sxx in /etc/rc2.d through /etc/rc5.d refering to Spark, in contrast to openfire, which I find as S20.

OpenFire is running fine including http SysAdmin Web interface.

Are there any tests that I can do to clarify what is happening? Would appreciate any help and tips.
