在 Ubuntu Gnome 13.10 中，尝试全屏观看 Flash 视频只会冻结视频。冻结可以通过取消聚焦并重新聚焦窗口来解决，但我无法让 Flash 全屏。但是，当我观看（非嵌入式）YouTube 视频时，全屏播放正常。
有人能告诉我如何解决这个问题吗？YouTube 似乎（几乎）可以工作，但其他功能却不行，这似乎很奇怪。
如果您需要的话，以下是我的详细系统规格：

感谢您提供的任何帮助。这个问题困扰了我一段时间，我终于受够了，所以考虑到我有多沮丧，任何解决方案都是好的解决方案。
答案1
我在 Mozilla 网站上找到了解决方案（https://support.mozilla.org/en-US/kb/flash-video-wont-play-full-screen) 在启动器中添加env LD_PRELOAD=/usr/lib/libGL.so.1之前就足够了firefox。无需任何改动即可为我解决问题。
答案2
所以正如你所说，这可能是 Adobe 的错误，
- 打开终端并输入
sudo apt-get update - 然后打开软件中心并点击“更新”（类似这样的操作） 它将显示可升级的物品列表
- 滚动查找“adobe”、“mozilla”、“media player”、“media runner”或“全屏命令”。
- 如果发现它们，请更新它们
- 完成后，重新启动计算机。
- 再次打开终端并输入
sudo apt-get update - 运行 Mozilla Firefox 你就完成了！
