Mathematica rendering 3D plots problems
aboSamoor | July 22, 2009 | 11:18 amRendering Graphics3D using Mathematica on linux generally and specifically on Ubuntu 9.04+ is not fun. The output is not displayed till you rotate the object, and once you rotate the 3D object the cpu usage jump to 100% which gives bad experience using Mathematica for Ubuntu users. This is a driver issue which it is expected to be addressed with the newer Intel graphics drivers which introduces UXA option instead of EXA as an acceleration method. As 9.04 was released this new technology was not stable enough to be enabled by default.
Now, to solve the problem for Mathematica you have two options:
- Run Mathematica with mesa option
mathematica -mesa -
- Modify /etc/X11/xorg.conf to add the UXA option
Section "Device"
Identifier "Configured Video Device"
Option "AccelMethod" "uxa"
EndSection - Logout to restart the X server
- Modify /etc/X11/xorg.conf to add the UXA option
Notice: Don’t forget to backup your xorg.conf before editing

I'm using Mathematica 7 on Ubuntu 10.04 and the UXA
Ryan | August 29, 2010 | 2:29 amI’m using Mathematica 7 on Ubuntu 10.04 and the UXA option didn’t help, but the “-mesa” fix worked great. The CUP usage is still pretty high but I think it is to be expected with 3D rendering.
