[gradsusr] Grads 2.1.a3 - Problem plotting Intel graphic

Thu Jan 12 04:22:25 EST 2017

Hi Jennifer, 

Thank you for the links. 

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. 

We have other servers or virtual machines that runs Centos 5.x and grads 2.1.0 works like a charm. 

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? 

I tried on the same Lenovo PC with Xubuntu 16.04 with XFCE and it doesn't work too. 

Maybe it's a libcairo problem in combination with newer X11 ? 
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... 

Best Regards, 

Simone

Hi, Simone — 
Please see an earlier thread on this topic: http://gradsusr.org/pipermail/gradsusr/2016-November/040443.html 
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.

Hi all, 

I'm posting here after days of searching and testing with no results. 

I have a specific problem that seems to affect Grads 2.1.a3 ( but I think even the latest versions ). 

I can reproduce it, with my specific input files like with the official grads test too. 

Here are some details of my tests: 

Hardware: 

PC Lenovo with Intel(R) Core(TM) i3-4170 CPU with integrated Intel graphics. 

PC HP DC7900 ( old 2008 model with Intel graphics too ) 

Software: 

O.S. Linux Ubuntu 16.04 

Kernel 4.4 & Kernel 4.5 

With and without Intel graphics update tool 2.0.2 installed 

Used Grads 2.1.a3 as binary downloaded from your site or package from ubuntu 16.10 via apt pinning . 

Intel update tool packages installed: 

ii i965-va-driver:amd64 1.7.1-0intel1 amd64 VAAPI driver for Intel G45 & HD Graphics family

ii vainfo 1.7.1-0intel1 amd64 Video Acceleration (VA) API for Linux -- info program 

Problem: 

I cannot graph correctly the image, in attach the results with model.ctl file used as a test. 

With grads 2.0 no problem everything is ok in this PCs. 

I think it's a Intel graphic problem, but Kernel upgrades , Intel drivers updates doesn't change anything. 

Do you have any ideas? 

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! 

Any help is really appreciated, 

Regards all 

Simone
