Mathematica 6.0 and Hardy heron

[anu7df]

I recently upgraded to hardy (clean install) and since then I have been having a few problems with mathematica 6.0. The graphics display looks horrible and the label texts are unreadable. Also running mathematica from terminal gives a segmentation fault even though it continues to run after that and everything appears fine except for this graphics bug. I thought initially that this might be a font problem, so I downloaded the latest fonts from the mathematica website and added it to my font path but that didn't make a difference. Combing through the forums, I find a few other bug reports about invisible texts etc but nothing like what I am facing. has any one noticed such issues? I have attached an image with this post of a simple plot showing the problem.
Thanks

I had font problems and solved them by running mathematica with the -defaultvisual option. You could try that - it might help.

I had tried this already. It didn't help. I am guessing this is not just a font problem, as the font is visible, only with less "fidelity".
Thanks

A recent post suggests that the QT4 libraries supplied by Wolfram are incompatible with Hardy. It suggests removing

/usr/local/Wolfram/Mathematica/6.0/SystemFiles/Libraries/Linux/libQtCore.so.4
/usr/local/Wolfram/Mathematica/6.0/SystemFiles/Libraries/Linux/libQtGui.so.4

Linux replaced with Linux-x86-64 on 64bit systems.

Starting with the usual command mathematica (as opposed to mathematica -defaultvisual) now provides perfect rendering of fonts in a notebook. I have reported this to Wolfram's support group.

Had this problem too, thanks a lot!

after deleting libQtCore.so.4 and libQtGui.so.4 from mathematica directory, don't forget to install the libQt4Core and libQtGui4 from the repos (i.e. using apt-get or synaptic)
this fix works like a charm... i have beautiful fonts now!!! thanx for your help on this....

FWIW - deleting/replacing the Qt libs is not the best idea - Mathematica uses the commercial versions of the libraries, which may differ from the open source versions...

I think this type of problem can be overcome by using matlab.. If you are not familiar with matlab, then read online help of mathematica.. Hope you can rectify your problem..

To be fair, MatLab and Mathematica are very different program.

for me the "-defaultvisual" option worked just fine! thank you very much BaffledMollusc!!

Hello I am using a Debian lenny and I have the same problems with fonts.
If I use mathematica -defaultvisual, the things work fine. But
if I remove the libQtCore.so.4 and libQtGui.so.4 from the Mathematica path
I get an error like this:

QObject: Do not delete object, 'unnamed', during its event handler!

and I have these libraries in the /usr/lib/.

I know that is not a Debian forum, but if someone has any idea I would be
thanks.

I know that in Mathematica 6.03 the fonts/display issues in Ubuntu have been fixed. If you can, get your hands on the update then everything will be worked out. Not a fix but I hope it helps.
