从 19.04 升级后，我正在设置 20.04，其中一部分是让我的 MM 密钥与 spotify 一起使用。在尝试制作自定义快捷方式时，我遇到了问题。在预先存在的系统快捷键上，我键盘上的 MM 键被注册为有效输入，并且可以分配：

但是，在尝试将键绑定分配给自定义快捷方式时，无法识别按键，并且我留在了此屏幕上：

到目前为止我已经尝试过：

  • 正如评论中所建议的那样，按照这篇文章的建议禁用默认播放/暂停键dconf-editor。没变。
  • 我尝试使用第二个键盘（也使用媒体键），但无济于事
  • 我试图绑定一个键并解绑它，也没有帮助
  • 环顾四周，gnome-tweaks以防某些内容被添加/更新但找不到任何东西。
  • 遇到这篇文章，但是，那里的解决方案现在出现错误：
david@david-pc:~$ gsettings set org.gnome.settings-daemon.plugins.media-keys previous ''
expected value:
  (empty input)
  ^
  • 更新到 kernel 后5.4.0-28-generic，媒体密钥短暂工作，然后似乎又随机停止了。重新启动后，媒体密钥再次开始工作，然后在大约 15 分钟后立即停止工作。

这是一个错误，还是我做错了什么？无论哪种方式，我都会喜欢一个答案/解决方法。

我使用 gnome-shell 3.28.4 安装了全新的 vanilla 18.04 LTS。我正在使用有线 Apple 铝制键盘：

在此处输入图像描述 我想在各种最终用户应用程序（Firefox、CLion 等）中使用顶行 F 键作为键盘快捷键，但每当我按下其中任何一个时，gnome/X11 堆栈中的某些东西（我假设）正在拦截它们并将它们解释为“媒体”键。据我所知，这样的 F 行按键不会传递给任何应用程序。

例如，如果我按 F5，我希望 Firefox 重新加载当前网页，或者让 CLion 触发构建，但是，唯一发生的事情是屏幕上覆盖了以下巨大图标：

在此处输入图像描述

我玩过gnome-tweaks设置应用程序，但无济于事。我也环顾四周dconf-editor，但我不熟悉它，也没有改变任何东西，因为我不知道我在做什么。

我做了很多搜索，但我得到的唯一点击似乎来自那些媒体不工作的人（他们希望他们工作）。需要明确的是，我想完全禁用媒体键。

有谁知道如何做到这一点？谢谢！

我有 Ubuntu 16.04。我键盘上的媒体按钮（上一个、播放/暂停、下一个）随机工作或不与 Spotify 一起工作。

所以有时当我按下按钮时，他们完成了工作，然后他们就停止了工作。有时它们会恢复正常运行。（dec）增加音量的按钮始终有效（但音量是系统范围的，而不是 Spotify）。

如何解决？

我在 Ubuntu 18.04 上使用 Das Keyboard 4。今天重新启动后，我的三个媒体键停止工作，暂停/播放键和上一个/下一个曲目键。

但是，静音键和音量轮仍然有效。

我尝试了以下事情但没有成功：

  • 进入键盘快捷键设置并明确设置这些快捷键的键。它似乎确实注册了按键，但设置或清除快捷方式无济于事。
  • 根据Media Keys not working on Ubuntu 17.10中的讨论在 dconf-editor 中乱搞——我尝试完全清除这些快捷方式的设置，但什么也没做。
  • 我尝试创建一个自定义快捷方式以dbus-send --print-reply --dest=org.mpris.MediaPlayer2.rhythmbox /org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.Player.PlayPause按照相同的讨论运行，但我无法将它与键盘快捷方式应用程序中的暂停/播放键相关联。当我尝试为此自定义命令设置快捷方式时，它根本不会注册被按下的暂停/播放键。如果我将它绑定到 Ctrl+Alt+Shift+P 它确实可以工作（但我想要我的媒体键！）。

这是令人难以置信的烦人。如果有人知道如何解决它，我将不胜感激。

我在 Ubuntu 19.04 上使用统一桌面

但是媒体快捷方式不起作用我搜索并执行此解决方案：

媒体密钥在 Ubuntu 17.10 中不再起作用

键盘快捷键在带有 Unity 的 Ubuntu 18.04 上不起作用

现在我尝试用命令行来做：

Play:

dbus-send --print-reply --dest=org.mpris.MediaPlayer2.spotify /org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.Player.Play

Pause:

dbus-send --print-reply --dest=org.mpris.MediaPlayer2.spotify /org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.Player.Pause

Play/Pause toggle:

dbus-send --print-reply --dest=org.mpris.MediaPlayer2.spotify /org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.Player.PlayPause

Previous:

dbus-send --print-reply --dest=org.mpris.MediaPlayer2.spotify /org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.Player.Previous

Next:

dbus-send --print-reply --dest=org.mpris.MediaPlayer2.spotify /org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.Player.Next

但我有这个错误：

Error org.freedesktop.DBus.Error.ServiceUnknown: The name org.mpris.MediaPlayer2.spotify was not provided by any .service files

wtf，我在 repo 中搜索： https ://packages.ubuntu.com/search?suite=disco&arch=any&mode=filename&searchon=contents&keywords=org.mpris.MediaPlayer2

并这样做：

sudo apt-get install mopidy-mpris mpdris2 -y

现在为什么这些命令不起作用？medias 密钥是否与此命令无关？

我该如何解决这个问题？

在我打开从 spotify 存储库安装的播客时发现我安装的版本 (1.0.77.338.g758ebd78) 立即崩溃后，我使用sudo software-properties-gtkSnap 将其从我的存储库中删除并安装它。
现在，它不再出现，apt list --installed但它就在那里，snap list现在是最新版本 (1.0.80.474.gef6b503e)，播客工作得很好。
但是，我有媒体快捷方式可以播放/暂停，跳到下一首曲目并返回上一首曲目，我什至将它作为默认音乐播放器，我通过将 %U 分配给它的 .desktop 文件来做到这一点。
媒体密钥不再起作用，我终生无法在任何地方找到 .desktop 文件。
我正在使用 Ubuntu 18.04。
任何帮助将不胜感激。
*编辑：现在，媒体控件正在工作。我没有做任何特别的事情，但我记得使用sudo snap refresh和使用sudo apt dist-upgrade可能就是这样。但是，我仍然需要帮助将 Spotify 重新设置为默认音乐播放器。

我在 Ubuntu 18.04 上使用戴尔 XPS13，当我使用默认桌面环境（Unity？GNOME？）时，我可以很好地使用屏幕亮度键。但是，当我使用 i3 登录时，按键不再调整屏幕亮度。

我尝试按照不同的指南通过 i3 配置添加键绑定，但它依赖于使用 xbacklight，当我直接安装和使用时无法调整我的屏幕亮度。

如何将此功能从默认桌面环境移植到 i3？

如果我在 Ubuntu 17.10 上调高音量，它有时会持续到最大。鉴于我只按下了一次按钮，理论上它应该只将音量增加一步。请注意，我只知道音量控制按钮发生的问题，而不是任何其他调整音量的方法，因为我从不使用这些方法。

我该如何解决？
