Hi everybody,

I just installed a trial of Mathematica 7.0.1 to see how it improved 
from the previous Mathematica 5.2 that I still had. Slightly 
disappointing is the fact that the MathKernel does not output graphics 
anymore, that is,

> ~/bin/math
Mathematica 7.0 for Linux x86 (64-bit)

In[1]:= Plot[x^2, {x, -1, 1}]

Out[1]= -Graphics-


Without popping up a new window with the graph as it used to in Math5. 
$DISPLAY is set and valid. Even when I forcibly unset it, there is no 
warning from the graphics output subprogram (that used to start in 
Math5) that DISPLAY is empty.

I found this [ ] thread in this newsgroup 
archive mentioning similar issues; however, if directing MathKernel to 
output in StandardForm or TraditionalForm, the -graphics- won't be a 
-graphics-, but a point list and parameters of the plot (I'd really 
prefer the drawn plot ;)

In[2]:= StandardForm[Plot[x^2,{x,-1,1}]]


>GraphicsBox[... lots of text ...]

What could be up with MathKernel7 that it produces no Graphics? With the 
graphical interface (~/bin/mathematica), plots are in fact shown, but 
I really prefer running just the MathKernel CLI.
