#Webots dongle not working driver
So, updating graphic driver made my linux unable to boot up right. If I remove the line emit postWorldLoaded(reloading, isFirstLoad), then webots run nicely, but I don't get the 3D view of the model, which is understandable in that case. Main.cpp:207 in int main(int argc, char *argv) : return app.exec() WbGuiApplication.cpp:322 in int WbGuiApplication::exec() : loadInitialWorld() WbGuiApplication.cpp:529 in void WbGuiApplication::loadInitialWorld() : if (!mMainWindow->loadWorld(mStartWorldName)) WbMainWindows.cpp:1332 in bool WbMainWindow::loadWorld(const QString &fileName, bool reloading) : const bool success = WbApplication::instance()->loadWorld(fileName, reloading) WbApplication.cpp:348 in bool WbApplication::loadWorld(QString worldName, bool reloading) : emit postWorldLoaded(reloading, isFirstLoad) _a = // I got 2 times the sames values, is it just luck or not ? In : void WbApplication::postWorldLoaded(bool _t1, bool _t2) Setting a breakpoint on this line (:385) give me : :385:QMetaObject::activate(this, &staticMetaObject, 1, _a) WbApplication.cpp:348:emit postWorldLoaded(reloading, isFirstLoad) īefore that, Webots run ok, but if I let gdb run this line, everything explode. Turn out that the point where everything blows up is : I believe that the different popup that appear are random, and only caused by the fact that they show up only after some time. I've been able to reproduce the bug each time. Operating System: Linux Ubuntu 20.04.2 LTS.Open a world (I wish to not share it for the moment, I'm using it at work.).My world is not that complex, a 4 wheeler style robot, and some OSM data to show surrounding building as box.
Note that opening another world (which load fine), and then "Open a recent world" allows me to load it successfully. Note that the loaded world was working fine before this weekend. Drop back to terminal, send SIGKILL to webots, and the process seems to effectively disappear (nothing in htop).īut coming back in GUI, Webots is still here, still hanging and oscillating as before. More painful, it basically freeze my screen. When opening a personal world, Webots hang at the step "Finalizing nodes".Īdditionally, it's randomly oscillate between 84% and 99%.Ĭlicking on the mini box of loading seems to trigger the oscillation as well.
