Thanks guys for figuring this out. I ran into the exact same problem
earlier this week with Ubuntu 18.04. I'm using CompositeViewer similar to
the "-3" case of the osgcompositeviewer example (multiple Views in one
window). I call osg::GraphicsContext::createGraphicsContext(traits) with my
custom
Sorry, I meant the samples that use it. You're right.

This hasn't looked like an OSG bug too me, just a usage issue. What
specifically do you
Hi Robert,
Your answer almost fixed my issue. There is just one
problem wsi->getScreenSettings(), still queries the wrong session:
1 screen(s) detected
Invalid MIT-MAGIC-COOKIE-1 keyUnable to open display ":0.1".
Screen #0 : 0x0 0Hz 0 bit
The problem is screen_id(screen), since it is not 0.
Okay that's how it works
it would be good to integrate these changes in all examples using
osg::GraphicsContext::WindowingSystemInterface

Sounds like we are getting to the bottom of things now :-)
FYI,
Sorry again
After a lot of bullshit here's a correct answer
for your code you should replace
wsi->getNumScreens()
with
wsi->getNumScreens(osg::GraphicsContext::ScreenIdentifier(1))
to work on DISPLAY=:1.0

Sorry I misinterpreted the code and said bullshit
there's really bug in X11WindowingSystemInterface reporting 0 screens

WindowingSystemInterface is an interface implemented in system dependant
osgViewer::XXXWindowingSystemInterface
What may be done is to add a system agnotistic windowInterface in osgviewer
#ifdef SYS
typedef osgViewer::SYSWindowingSystemInterface osgViewer::WindowingInterface
#else if SYS2
Hi Robert,
Thanks for the quick response.
I have created an example:
https://github.com/omaralvarez/osgtest
osgviewer runs fine, no errors in console. But if I use INFO, I can see:
Viewer::realize() - No valid contexts found, setting up view across all
screens.
It may be related, but I'm not
Hi Omar,
What happens when you run osgviewer? Do you get errors output to the console?
Do any of the OSG examples fail?
If we can't see the error in standard OSG examples then it may be
worth creating a small test program so that others can run it on their
own systems to see if we can
osg::GraphicsContext::WindowingSystemInterface* wsi =
osg::GraphicsContext::getWindowingSystemInterface();
if ( !wsi ) {
std::cout << "ERROR. Could not access the Windowing System
Interface" << std::endl;
throw -1;
}
std::cout << wsi->getNumScreens() << "
14 matches
