我在冻结帧上覆盖文本时遇到困难：虽然我能够在我选择的拼接剪辑上应用运动冻结效果，但当我在上面的轨道上添加标题文本时，冻结效果停止。这非常麻烦，因为我需要在选定的框架上标记特定组件。
我已经提到过关于冻结帧问题的先前帖子，但没有看到覆盖文本的困难。
我正在运行最新版本的专有 nVidia 驱动程序，直到几天前在调整了我的主题之后，我才在启用 Compiz 效果时遇到任何问题。当我尝试从外观面板启用效果时，我得到这个弹出窗口：
而且，在工作了几秒钟后，它变成了这样：
从命令行或应用程序菜单启动 Jockey，它无法识别我的专有驱动程序，也无法成功完成包索引下载。jockey.log 的输出：

有谁知道解决这个问题的方法？我想念我的效果。
我正在制作一个视频，我想做关键帧的速度变化。也就是说，我想让视频在不同点逐渐变快或变慢。我一直是 kdenlive 的用户，但不幸的是发现无法做到这一点。有没有推荐的软件绝对可以做到这一点？
我有带 VGA 兼容控制器的 lenovo g460：nVidia Corporation GT218 [GeForce 310M] (rev a2) 显卡
我已经使用gksudo jockey-gtk命令安装了驱动程序，但是当我将视觉效果更改为额外时，它会给我“无法启用桌面效果”。我是 Ubuntu 的新手。
我想使用 VMware Player 在 VM 中测试 Unity。我已经在显示选项中启用了 3D 加速，并且安装了 VMware Tools。但是，当我尝试运行 Unity 或尝试在外观菜单中启用效果时，它不会激活。Jockey 说只有一个视频驱动程序可用，并且已经启用。
我不想使用 VirtualBox。
在 Gnome-shell 中，我们不再有 compiz 了吗？在 KDE4 中我们有原生的桌面效果，我想知道我们是否还需要 compiz 的 Gnome-shell。
