在 Ubunto Focal Fossa 20.4 上,对于大多数应用程序,例如通过搜索 VeraCrypt 并按 Enter 键,Ubuntu 会在我的屏幕顶部显示一条通知,上面写着“VeraCrypt 已准备就绪”。我必须单击此通知,以便我要打开的应用程序出现在前台。有没有办法改变这种默认行为?
这是我目前用来为 url 创建快捷方式的代码

我想用firefox做同样的事情,因为我不使用chrome,我尝试用firefox制作一个,但它没有给你全屏并显示添加新选项卡选项我用Exec替换了
/usr/bin/firefox --new-window http://www.cyberciti.biz/
我需要这样的东西不是firefox的结果执行替换
PSPP 统计分析程序对研究非常重要,我用它完成了我的研究生毕业,使用的是 Ubuntu 19.10,但它不存在于 Ubuntu 20.04 LTS 存储库中,因此我们可以轻松安装它。为什么?
我是一名数学老师,必须在这次封锁中通过视频教我的学生。现在我想要的只是查看表达式和方程式。我的目标是通过共享我的屏幕并使用某种能够在旅途中显示结果的 LaTex 编辑器来实现这一点。我知道有一些在线工具。但是有没有这样的应用程序原生于 linux。我不希望使用此编辑器构建复杂的文档。只是某种拆分视图,我的乳胶将在我键入时或在每个语句之后变成表达式。
因为无法在互联网上找到答案,我觉得自己很失败。互联网历史上一定有人问过这个问题。但我不能,所以我们开始:
我有一台旧的 macbook air,macOS 和 ubuntu 安装在同一个硬盘上。这台 Macbook 有 64GB 的内部 SSD,对于我的工程工作来说太少了,我需要在机器上安装大量的应用程序,所以我买了一个 512GB 的 nvme SSD 来为应用程序和个人文件留出额外的空间。
我怎样才能让内部 SSD 上的 linux 能够将其应用程序文件安装在外部 SSD 上?
我认为问题是如何为内部 SSD 中的所有系统库和外部 SSD 上的应用程序二进制文件提供根目录?如果我错了,请纠正我,并请提供我想学习 linux 的最多信息。也许我对信息学很感兴趣。
在单独的硬盘驱动器上安装应用程序 这个答案很差,我认为与我的问题没有直接关系,因为我需要 /usr 在不同的驱动器上?如果我的术语有误,请纠正我。
一旦我启动 slack app(snap),我就会在 Ubuntu 18.04 中退出我的用户。
如果我可以在注销之前检查一下,我会提供更多信息。您能否建议我如何检查一些日志以及如何解决此问题。

我想在 Ubuntu 16.04 上运行游戏。当我尝试使用 wine 软件安装游戏时,它无法识别文件扩展名。
Setup.vbe
,有什么办法可以运行这个。?
我在 Ubuntu 17.10 的应用程序概述中看到一个名为“Browse”的程序。
这个应用程序是做什么用的,它是 Ubuntu 17.10 的默认应用程序吗?
单击启动器不会执行任何操作。

我相信它的发射器是/usr/share/applications/org.laptop.WebActivity.activity.desktop
.
如果我尝试Exec=
从命令行上的.desktop
文件运行命令,则会收到以下错误:
