好的,菜单栏右上角的时钟不见了。以下是我所知道的:
我使用的是 2016 年 4 月 12 日版本的 16.04。
我第一次安装操作系统时,时钟就出现了。即使现在我的用户帐户中没有了时钟,但它仍然存在于访客帐户和登录屏幕上。
设置->时间和日期中的时钟设置选项显示为灰色,根本无法与其交互。
经过多次试验,我发现问题可能与我在 15.10 中使用的应用程序的安装有关。我编写了 shell 脚本来恢复我拥有的所有内容。
在单独安装项目并重新启动以尝试查看原因之后,我证实了我的怀疑,即它与我安装的 PlexMediaServer 有关。我在下面包含了为此安装运行的 bash 脚本。
要安装 Plex,我首先从网上获取安装程序并运行它。然后,我从外部驱动器复制备份的元数据并设置权限。然后,由于我的所有媒体都在外部驱动器上,我需要将其安装在单独的文件夹中,以便我可以更改权限,让 Plex 可以看到它。
我觉得文件夹安装最有可能是问题的根源,但我不确定。包括下面的 bash 脚本。任何建议都将不胜感激。
