<p>GRADS/Cairo display doesn't work on my machine (RHE7). <br>

<p>xdemo.c works fine. It opens a 500x500 X window, draws 24
concentric circles made up of tiny line segments in varying shades

This problem is bad, and I want it to be resolved too. There are
so many complicating factors it is difficult to figure out where
to begin and it’s especially tough for me because I am not able to
duplicate it. The fact that it is hardware dependent just makes it
worse. I don’t think it’s a problem unique to GrADS, but I could
be wrong. One way to simplify things is to use a smaller C program
(like xdemo.c) that uses Cairo in the same way that GrADS does but
without all the other supplib baggage.
<div><br>
</div>
<div>Can you test whether my sample program xdemo.c works on all
your various setups where GrADS X11 displays fail? You will have
to build the Cairo library from source. Maybe the problem is
simply that we are not using the very latest version of Cairo
and all of its dependents, and an upgrade is all that is needed
for GrADS to work on these newer systems. That would obviously
be the easiest solution.</div>
<div><br>
</div>
<div>The other thing that confuses the issue is the X11
client-server interaction. I do all my work on a MacBookPro. I
use xterm to open windows to access my local operating system
(OSX 10.9.5) and also to ssh to remote servers (at this point,
only redhat 5 and 6). The rendering is done by the X11 server on
my local machine (XQuartz), not the remote systems I am
connected to using ’ssh -Y’. GrADS is dynamically linked with
the X11 libraries; I have no idea whether libX11 and libXext are
different on OSX v. red hat 5/6 v. redhat 7 v. ubuntu v. fedora,
but maybe that is the source of the problem. </div>
<div><br>
</div>
<div>The Lenovo hardware is a different beast altogether, a
laptop/desktop box that has its own flavor of unix and X11
server. I know nothing about these systems; if the brand of
graphics cards makes a difference then it’s a software issue at
a much lower level than where GrADS is working. Do you think the
display would look right if I used an xterm on my Apple laptop
to ssh to a Lenovo box and ran GrADS remotely? </div>
<div><br>
</div>
<div>I am working on new releases for GrADS, where the graphics
back ends for printing and display are dynamically loaded as
shared objects based on user-provided arguments on startup. That
would mean you could take advantage of all the other
improvements since version 2.0.2 but not depend on Cairo for the
display. I have to get the configuration issues ironed out
before I can make it public. </div>
<div><br>
</div>
<div>I will ask my systems administrator if he can set up a RHEL7
sandbox for me, but in the meanwhile please try the things I
have suggested and let me know what works/fails. It’s not called
the cutting/bleeding edge for nothing! </div>

GRADS/Cairo, which was reported to the forum about a

<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>

<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>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>Any help is really
appreciated,</div>
