Hi, Simone —
<div>Please see an earlier thread on this topic: <a href="http://gradsusr.org/pipermail/gradsusr/2016-November/040443.html">

<div>The problem is with ubuntu's X11 server; as you noted it works on Fedora and CentOS. You should be fine if you use batch mode. </div>

<div>Hi all,</div>
<div><br>
</div>
<div>I'm posting here after days of searching and testing with no results.</div>
<div><br>
</div>
<div>I have a specific problem that seems to affect Grads 2.1.a3 ( but I think even the latest versions ).</div>
<div><br>
</div>
<div>I can reproduce it, with my specific input files like with the official grads test too.</div>
<div><br>
</div>
<div>Here are some details of my tests:</div>
<div><br>
</div>
<div>Hardware:</div>
<div><br>
</div>
<div>PC Lenovo with Intel(R) Core(TM) i3-4170 CPU with integrated Intel graphics.</div>
<div><br>
</div>
<div>PC HP DC7900 ( old 2008 model with Intel graphics too )</div>
<div><br>
</div>
<div>Software:</div>
<div><br>
</div>
<div>O.S. Linux Ubuntu 16.04</div>
<div><br>
</div>

</div>
<div>With and without Intel graphics update tool 2.0.2 installed</div>
<div><br>
</div>
<div>Used Grads 2.1.a3 as binary downloaded from your site or package from ubuntu 16.10 via apt pinning .</div>

<div>Problem:</div>
<div><br>
</div>
<div>I cannot graph correctly the image, in attach the results with model.ctl file used as a test.</div>
<div><br>
</div>
<div>With grads 2.0 no problem everything is ok in this PCs.</div>
<div><br>
</div>
<div>I think it's a Intel graphic problem, but Kernel upgrades , Intel drivers updates doesn't change anything.</div>
<div><br>
</div>
<div>Do you have any ideas? </div>
<div><br>
</div>
<div><br>
</div>
<div>I cannot use other distributions , I use grads without problems on various Fedora and CentOS servers, but in this case I need it to work with this Ubuntu version and hardware!</div>
<div><br>
</div>
<div>Any help is really appreciated,</div>
<div><br>
</div>
<div>Regards all</div>
