Could you try running Gazebo by itself on verbose mode as follows and see if any error messages are printed?

gazebo --verbose

The first time you run it, Gazebo may try to download some models from the internet, and this can take a while depending on your internet connection.

Echoing @bfsgr, the the gazebo fedora package has the same problem, as reported at https://bugzilla.redhat.com/show_bug.cgi?id=1871291

I've been trying to debug this in various ways, such as using a newer version of OGRE, updating from gazebo-10.1.0 to gazebo 11.1.0, using Intel and Nvidia graphics, without any luck.

Running with gazebo --verbose, I get:

The GTK issue seems to be related to Qt. And nethogs doesn't show any network activity (e.g. downloading models) from gazebo.

For reference, my current test setup is:

  • Fedora 32 x86_64
    • nvidia driver 440.100, using bumblebee
    • Qt 5.14.2
  • gazebo-11.1.0
  • ogre-1.12.8

The issue should be reproducable with the stock packages in fedora 32. A few patches are needed to build gazebo on Fedora, but none of them look to me to affect rendering (un-bundling skyx is the only thing that I think might be related - in my testing I disabled that patch and am using gazebo's built-in skyx). I can help debug and try things if needed.

I let Gazebo run over night and model opened just the black scene. This was 1st reported in 2018 any ETA on a fix now that 11.1 is out?

I am not sure if it can help, but you can find some info related to Ogre 1.12 also in #2700 .

If you are able to build and run the Gazebo test suite, that probably could provide some useful information on what it is working and what is not.

Fair enough. Running ctest I see that UNIT_Dem_TEST segfaults, which I'm looking in to. Then, UNIT_Actor_TEST hangs and times out.

I think this test is trying to connect to a gzserver, so if the gzserver isn't responding, it makes sense that the test would never connect and hangs. It could also be why the client never renders anything.

The full test output is:

Running ctest I see that UNIT_Dem_TEST segfaults, which I'm looking in to.

Reported as #2828

Surprisingly, if you set -DENABLE_PROFILER=ON when calling CMake, the tests start passing, and gazebo launches normally and shows the default world. At a CMake level, that option appears to just be changing the visibility flags and enabling a macro. I'll see which of those causes the change.

@richmattes

The symbol visibility flags are what's causing the problem for me. To be sure, I did a clean re-build (using mock) of the f32 gazebo-10.1.0 package, changing only the symbol visibility flags (removing -fvisibility=hidden from the root CMakeLists.txt). With that change, gazebo no longer launches with a blank screen - the splash screen disappears after a few seconds and I see the ground plane in the 3D view.

Can you provide a link to the F32 package and the build how-to instructions?

@richmattes this error message is suspicious to me, though it may be a symptom and not related to the cause. Does this message still appear once you've adjusted the visibility flags and things are working?

That warning is coming from gzclient. I still see it after I've adjusted the visibility flags. I tried to set a breakpoint at that source file/line, and on gazebo::common::Console::warn, but for some reason neither would trigger.

I was able to set a breakpoint on the destructor that the message is printed in. It trips four times during program startup, but since it warns based on time, and I'm slowing things down with the debugger, I'm unsure which one is printing the error.

Backtraces (they all look the same):
