To your questions: 32/64 bit arch -> I am running 32 bit

I will try again by completely removing things you mentioned
from synaptic, and
I don't blame Linux for this not working on my desktop.
In my original post, I noted that this works fine on my laptop,
where the differences (other than physical and hardware) are that
the laptop xubuntu OS was installed using ALternate Install CD.

Whether that is the reason it works on Laptop, remains to be seen, but I doubt
it.

An alternate point to consider in all this is ==>
The sooner that things work in all platforms (Mac, Win, Linux),
is the sooner that computer users will realize that for Free, you can have a
really great,
workable, functional Desktop environment of your choosing.

For instance...have you tried GNOME, and like KDE or XFCE better, that's great!

Tried XFCE and prefer the speed of Fluxbox? Go for it.
Want to mix & match [file mgrs, window mgrs,etc?] That'll work too! -- Choose
and ENJOY!
Want to experiment with a bunch of distros without writing/formatting the HD?
Sure thing - burn a live CD.


That sort of flexibility simply isn't anywhere near abundant on Windows or
Apple.


Shame on you Adobe, for I don't see any reason that this plugin's
functionality/stability should be so irksome to so many Linux/Firefox users.
