    如题,我的Ubuntu系统搭建了lxde桌面环境,运行命令DISPLAY=:0 ./cube -platform xcb会出现段错误问题

    Qt eglfs on x11是配置并编译成功了的,这个问题是否与桌面环境配置有关?

      最终还是自己排查问题自己解决的,目前EGL on X11 运行顺利。

      弄这个是真的搞我,CPU占用总算是降下了不少。

          段错误的语句位于qxcbeglwindow.cpp文件下:
          m_surface = eglCreateWindowSurface(m_glIntegration->eglDisplay(), m_config, m_window, nullptr);

          发现这个函数是一个egl通用的接口,有关这方面的问题我也不太懂,哪位大佬能解惑一下。
