Thanks

Not sure if it's related but we ran into some font engine problems in Purr Data last year that showed up in ubuntu 16.04.

Apparently somebody somewhere in the Gnu font stack "fixed" font-rendering such that a monospaced font like DejaVu Mono got rendered with a measurable difference in width compared to OSX, Windows, and every earlier Gnu font stack I could check.

Here's my comment about it in the Purr Data workaround:

+var font_engine_sanity;
+
+// Here we use an HTML5 canvas hack to measure the width of
+// the text to check for a font rendering anomaly. Here's why:
+//
+// It was reported that Ubuntu 16.04, Arch-- and probably most other Gnu/Linux
+// distros going forward-- all end up with text extending past the box border.
+// The test_text below is the string used in the bug report.
+// OSX, Windows, and older Gnu/Linux stacks (like Ubuntu 14.04) all render
+// this text with a width that is within half a pixel of each other (+- 217).
+//
+// Newer versions of Ubuntu and Arch measured nearly 7 pixels wider.
+//
+// I don't know what the new Gnu/Linux stack is up to (and I don't have the
+// time to spelunk) but it's out of whack with the rest of the desktop
+// rendering engines. Worse, there's some kind of quantization going on that
+// keeps the new Gnu/Linux stack from hitting anything close to the font
+// metrics of Pd Vanilla.
+//
+// Anyhow, we check for the discrepancy and try our best not to make newer
+// versions of Gnu/Linux distros look too shitty...

In Purr Data, systems using this new font stack will notice a small amount of extra padding at the right of the box. This is because as I mentioned the font engine quantizes the pixel font size such that fitting it to the box makes it slightly smaller than what would be ideal. Rather than making the box smaller, I purposefully keep the box size consistent across all platforms so that users on Ubuntu 16.04 and greater don't end up putting boxes so close to each other that they end up overlapping when viewed on Windows/OSX.

Hope that helps.

@NoDSP Yes, I tried to read very carefully all of the research that you have done (and more).

All that you say is true, but as Debian Sid is a currently "unstable release"... bleeding edge...not even released for testing except by developers (and stable Debian does not have this problem) https://wiki.debian.org/DontBreakDebian I think you are putting in a lot of work for no gain.

As the rendering is handed over to the OS, I still suspect the x-code or the graphics driver. A Ubuntu user found a solution to a very similar rendering problem by using his OS in a virtual machine.... https://forum.pdpatchrepo.info/topic/10884/pd-interface-rendering-bug-on-ubuntu-16-04

That you cannot set the -font-size flag on any Linux distro is an issue though, that maybe can be fixed easily if you report as a bug.
Yes, I still find extended more reliable and useful..... but a really massive effort was put in to make it so....

@alexandros. not sure how i installed it. I was using ubuntu 16.04 but never managed to solved it. As of today I´ve decided to reinstall ubuntu and everything works perfect it´s not the best solution but it works now. BTW i'm running same ubuntu and pd installed from command line.

This might help...:

pd2thoughtmap.desktop

Try the way you already have, but before doing so, cp this .desktop file into your /usr/share/applications folder.

You might have to restart XServer and/or reboot and/or rebuild menus to make this work.

Then do the "OpenWith" steps again. This might help Ubuntu "see" the script.

Not sure, but you might have to set (in that right-click menu) the "Properties" option to run "Allow executing file as program" and possibly further "Run in terminal".

If that does not work, the following pages (hope) might help:

http://helpdeskgeek.com/linux-tips/add-shortcuts-to-right-click-context-menu-in-ubuntu/

or (possibly with some manipulation) this:

https://sushantbhosale.wordpress.com/2011/10/13/send-to-script-for-nautilus-in-ubuntu/

note: this technique of writing file-types to right-click events is a Major technique to know, from right-click convert MOV2MP4, jpg2png, etc. etc. I use it often, if not every few actions It can also be set up to process directories, for instance, extracting the .wavs from all files.

@EEight It doesn't work, because it says that "El paquete «puredata» no está instalado", that puredata is not installed... isn't it rare?
