<p class="MsoNormal">Dear all,<br>
<br>
I recently install on my laptop (Intel M520 with Integrated Graphics Controller and Ubuntu 10.04.2 LTS) Paraview 3.10.1 pre-compiled binaries. Nevertheless, I had some problems with that version, it crashes when saving screenshot, the error is :<br>

----<br>
X Error: GLXBadContextTag 170<br>

<br>
Therfore, I decided to compile the source but I also had an error when I built Paraview. My configuration file is :
