That makes about twenty posts this week detailing nothing but problems
with Mathematica on Linux.  The BEST thing we've heard was somebody's
opinion that it might be worthwhile to run a Kernel on Linux (but not
the FrontEnd).

That's more than enough bad news to talk me out of switching to Linux.
I had been really considering it.

I'm running Mathematica 4.1 on SuSE Linux 8.0 with the KDE 3.0.3 and
XFree86 4.0.2.  
I was trying to run one of the Mathematica Book -> Graphics Gallery -> 
Animations -> Rolling Square.  I don't recall the exact sequence of
actions 
I took.  I believe I selected the cell with the square (the only cell in

the notebook) and from the menu, Cell -> Animate Selected Graphics.
This 
resulted in a set of animation control buttons appearing in the bottom 
frame of the window. I clicked on one of these buttons, but nothing 
happened.  I looke back in the menu and saw M-y as a keyboard shorcut to

run an animation.  I tried that with no result.  I clicked another
button 
in graphics control set, and my X windows locked up.  This included the 
keyboard's ability to give me another display by using Ctl+Alt+F1.  I
went 
to another system and ssh-ed in and found Mathematica had over 50% of my
user 
resources, and was climbing.  The same was true for VM.  I have a gig of

physical RAM.  Once I killed Mathematica, my X came back to life.

I've had several bad experiences with Mathematica and X.  I honestly
believe there 
is/are bug(s) in the Linux implementation.  I would very much like to
help 
isolate and fix these.  Have others had such problems?
