每次我尝试打开硬盘上的任何视频时，都会出现加载的迹象，然后什么都没有发生，然后我必须再次双击它才能正常打开。此外，当我右键单击视频并转到属性时，它会打开属性，但随后会冻结。此外，当我尝试从应用程序窗口访问终端时，它开始加载然后崩溃，但当我右键单击任意位置打开它时，它可以正常工作……我不知道发生了什么，也不知道如何开始解决所有这些问题。有什么帮助吗？

答案1
您的 HDD START 数据看起来正常，除了启动速度比正常情况下慢之外。
可能存在两个独立的问题，而且这些问题足够不同，所以我怀疑情况确实如此。
此测试将快速显示您是否缺少使用 Totem 视频播放器（又称视频应用程序）播放视频所需的编解码器。
安装甚高频液晶从 Ubuntu 软件应用程序或使用
sudo apt update && sudo snap install vlc
安装完成后，打开 VLC，单击文件，导航到视频文件，选择并运行它。
如果出现故障，请将 1GB 以下的视频文件复制到 USB 驱动器上，然后重新启动 VLC，导航到 USB 驱动器并播放该文件。
