Hi Magician,<br>
<br>
Good catch!<br>
I forgot to suggest another possible fix for your problem - define
the environment variable in a command line in VNC window from which
you launch ParaView:<br>
<blockquote>export LIBGL_ALWAYS_INDIRECT=y<br>
</blockquote>
<br>
Best regards,<br>

<pre wrap="">Hi all,
I've been trying to solve the problem.
I found an important setting about it.
Our ParaView is running on shared Linux cluster,
so we operate ParaView with VNC Client.
My VNC setting is very simple as below:
</pre>
<blockquote type="cite">
<pre wrap="">vncviewer -geometry [width]x[height]
</pre>
</blockquote>
<pre wrap="">But other users' settings are little different:
</pre>
<blockquote type="cite">
<pre wrap="">vncviewer -geometry [width]x[height] -depth 32
</pre>
</blockquote>
<pre wrap="">
The -depth option is critical.
Maybe this option influences OpenGL setting of VNC,
and ParaView gets into GLX errors.
I suggested removing -depth option and restarting VNC server,
then our ParaView executed perfectly.

I was trying to build ParaView on CentOS.
It looked OK, but today other users on our machine tried to run ParaView,
they got errors as below:

Maybe our ParaView tried to access my home directory from other users,
these errors are dumped.
I checked my CMakeCache again, and I found these parameters:
</pre>

<pre wrap="">
Maybe our ParaView's build setting depends on original source data on my home directory,
but it's not good for using many users.
Which is the best way to change our GL settings?
