Mathematica 7 slow under 9.04

[Buendia]

Hi,

After upgrading to 9.04 from 8.10 mathematica notebooks run very slowly. Running 'math' from the command line is fine though.

When mathematica frontend is running, both MathKernel and Mathematica processes consume 15% - 20% of the cpu, while no notebook is running.

Anyone else having the same problem?

Hello

I have the same problem. It was faster on 8.10 than on 9.04.
Thats especially a problem, because i am using a Netbook (Asus 1000H) and the Atom CPU isn't very powerful.
Its nearly unusable.

I tried to use the sun java jre too, but its no difference, its still very slow.

MathKernel, Mathematica and Java use 100% CPU power all the time. Also xorg seems to use more cpu when Mathematica is started and I click around in the window.
As far as i can remember, that wasn't the case with Ubuntu 8.10.

Any ideas?

Try reinstalling the fonts. May be that will help.
Here is a guide how to do this

I've tried it. I haven't noticed any difference.

I tried a few other things:
Using the system libraries (moved all libQT* and other libs that are already installed out of SystemFiles/Libraries/Linux).
Also no difference, except, that the GUI now looks a bit more like Ubuntu (uses the system QT libs with the Ubuntu style now).

But it also makes no difference...

On my desktop PC i can use it, but only because it has enough power. Mathematica uses also much CPU power there. So its definitly no hardware or graphics driver thing (but maybe another xorg related problem?)

Hope someone finds a solution.

I thought this happened to me because fglrx is no more supported for my ati card and the xorg driver is too slow. Can you confirm that mmt is still slow when you have your GPU manufacture driver installed?

Mathematica notebook interface under linux has always been a mess anyway.

Confirmed.

I am using Mathematica 7 on Ubuntu 9.04 with an Intel 945GME on my netbook with the xorg drivers shipped with Jaunty

and

I am using Mathematica 7 on Ubuntu 9.04 with an Radon 4870 on my pc with the fglrx drivers installed with the hardware driver thing in Jaunty.

It should be reported to wolfram then. Please send us the link to the mailinglist post if you're planning to do so. Unfortunately, their mailinglist is moderated in an ancient way and it could take up to 24 hrs before your post appears to everyone.

Hi All,

Using Mathematica 7 in Ubuntu 9.04 I have problems with charts created by Plot3D. After running this function, The plot is not displayed. Trying to rotate the plot, I can see it , but the fonts are unreadable. 2D plot woks very well. I try to reinstall the fonts, but it does not differences. I have a Intel 945GME on my Notebook. When run Mathematica, I get :

Failed to initialize GEM. Falling back to classic.

I have not noted so much differences about CPU Consumption. Any ideas??

Thanks to all!

I can confirm the same problem.. my system is

Has anyone introduced this shame to wolfram? (the company not the person, you can go for the latter too if you feel like it)

Please send us the links to your posts if so.
