MATLAB: Does MATLAB 7.3 (R2006b) crash the X-server session when I run the BENCH command multiple times

linuxlogoutMATLABopenglwindowsxx-windows

After installing MATLAB 7.3 (R2006b) on a 64-bit Fedora Core 6, MATLAB crashes the X-server when the BENCH command is run. This can happen when the BENCH is run anywhere from 2 to 10 times. There does not seem to be any problems with any other X applications that use X on this machine.

This could be an issue with the incompatibilities between MATLAB and the OpenGL driver, due to the numerous variants of OpenGL drivers for Linux. This shows up in the 3D graphics test portion of the BENCH command. When this type of error occurs, the X session is closed by the client.

Therefore, to workaround this issue, some customers have found it helpful to use the software version of OpenGL, by executing the following command after starting up MATLAB:

opengl software

This will force MATLAB to use software OpenGL rendering instead of hardware OpenGL.

The issue is that the OpenGL renderer for graphics in MATLAB may not work. There are a few workarounds and recommendations:

Before you begin, update the graphics driver to the latest version.

The first option is to change the OpenGL rendering mode to software with the following command, either before executing SURF or in 'startup.m'.:

opengl software;

If this does not resolve the issue, the second option is to try turning off the OpenGL renderer completely. Note that this will disable alpha transparency.

opengl neverselect;

Another option is to force a particular renderer by default, by using the following command:

% choose ZBUFFER renderer
set(0,'defaultFigureRenderer','zbuffer');
% alternatively, choose PAINTERS renderer
set(0,'defaultFigureRenderer','painters');

Using GLX (the OpenGL extension to the Xwindow) from Intel chips to Sparc chips is not recommended.

Some customers have found it helpful to use the software version of OpenGL, by typing

 opengl software

at the MATLAB command prompt.
