Thread Subject: matlab crash and session logout in suse 10.2

I've recently installed suse 10.2 and matlab Version
7.4.0.287 (R2007a) (64bits). It usually works fine, but when
displaying some figures, matlab crashes and makes a logout
of my linux session. It seems to happen quite arbitrarily,
once or twice a day. Have any of you had this problem before?

I've a similar problem. After clicking view>property editor
or double clicking on the figure window matlab crashes,
followed by a crash of the x-server, followed by a logout.
It seems to be a deep-laying problem with a call of a java
function that calls the x-server.
At a first-help, I've replaced the function showplottool by
a dummy:
function comp = showplottool (varargin)
comp = 0;
Now, matlab run stable, but the property editor is not
available. A limited acces to the figure propertys (via the
GUI) is given by edit plot (arrow symbol) and right click
on the axis, figure, etc.

Me too, every time I try to save the output of a figure, matlab crashes, seems something with java, but I have no clue how to solve it yet

I found an explanation of the problem here:

but there is no clear solution yet :S

A hint from the Mathworks support:
At every Matlab start set openGL to "software"

>>opengl software

It seems to be a solution of my problem.

It works for me too. Thanks a lot.

This fix just makes matlab crash when i create a figure. any
other suggestions?

I had a similar problem in Debian Etch on a Dell D620 with
the Intel integrated chipset. lspci gives:
00:02.0 VGA compatible controller: Intel Corporation Mobile
945GM/GMS/940GML Express Integrated Graphics Controller (rev 03)
00:02.1 Display controller: Intel Corporation Mobile
945GM/GMS/940GML Express Integrated Graphics Controller (rev 03)

At any rate, the problem does appear to be related to glx
software because when I install things like xlibmesa, the
problem *appears* to be fixed.

In debian, doing a:
apt-get install mesa-utils xlibmesa-dri xlibmesa-gl xlibmesa-glu

Appears to have fixed the problem.

Looks like the problem is with openGL. Try setting set(gcf,'renderer','zbuffer') or (gcf,'renderer','painters'). Setting "opengl software" at the beginning of each section also helps.

I got an official reply from mathowrks. This appears to be a problem with the opengl driver on linux. Short of installing the bug-free driver, the only other option is to set opengl to software at the begging of each matlab session. Without hardware acceleration, it may be faster to do figure rendering using zbuffer.

Thank you, this was very helpful.
