<p>Here at UND/AOSC we have multiple machines running RHE7. All have
the same display problem with GRADS/Cairo, which was reported to
the forum about a year ago. We here just stick with the 2.0.2<br>

<div>Hi Jennifer,</div>
<div><br>
</div>
<div>Thank you for the links.</div>
<div><br>
</div>
<div>My focus was on Ubuntu but this morning I made a few more
tests on Fedora ( we have one Fedora 24 ) and it doesn't work
on it too. I'm talking of the same hardware here ( Lenovo
Thinkcentre M93 with integrated graphics ).In attach a
screenshot of the grads example file plotted. </div>
<div><br>
</div>
<div>We have other servers or virtual machines that runs Centos
5.x and grads 2.1.0 works like a charm.</div>
<div><br>
</div>
<div>On one Lenovo Thinkcentre M93 with Ubuntu 16.04 LTS and
grads 2.1.a3 I bought an AMD Radeon R5 230 graphic card and it
instantly works perfectly without any specific AMD drivers
installed.If it's a specific X11 Ubuntu problem why it starts
working? </div>
<div><br>
</div>
<div>I tried on the same Lenovo PC with Xubuntu 16.04 with XFCE
and it doesn't work too.</div>
<div><br>
</div>
<div>Maybe it's a libcairo problem in combination with newer X11
? </div>
<div>You say it's an Ubuntu problem , is there a Bug open in
Ubuntu community for this ? I think it's a big issue, we have
all our users (about 50 clients) using this PC model and we
are stuck...</div>

Hi, Simone —

<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>Here are some details of my tests:</div>
<div><br>
</div>
<div>Hardware:</div>

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>
