在 Kubuntu 24.04 上，快捷键Ctrl+Space与更改键盘布局有关，但我需要在我使用的所有 IDE（Intellij、Visual Studio）中使用该快捷键。
我怎样才能让系统不再使用Ctrl+ Space？
自从升级到 24.10 以来，我的登录屏幕一直闪烁，但大多数时候都会长时间关闭，而当它打开时，持续时间几乎不会长达一秒钟。
有时我会在黑屏上收到一条消息，说out of range。
我仍然可以通过输入密码登录，幸运的是焦点默认为密码输入框，一旦我进入桌面，一切都很好。
有什么想法可以让我稳定我的登录管理器，或者这是否是目前已知的无法修复的错误？
我在 Kubuntu 24.04.1 上，并且我已成功通过添加它来挂载带有 cifs 的 smb 共享/etc/fstab，使用以下行：
//192.168.10.122/Test /mnt/Test cifs user,noauto,user=test,password=test 0 0
问题是密码是纯文本，不安全。因此，我遵循了新的指南，通过创建(读写)凭证文件 ( .smb_cred) ，并将此行改为：chmod 600
//192.168.10.122/Test /mnt/Test cifs uid=1000,credentials=/home/test/.smb_cred,iocharset=utf8 0 0
问题是它不起作用。我看到了已安装的文件，但它是空的。
我使用 NVIDIA GPU 的声音输出作为主声音接收器。不过，我时不时会插入 EPOS 耳机（一种与实际耳机进行无线通信的 USB 适配器）。
在 KUbuntu 22.04 下，pulseaudio 会自动切换到 EPOS 进行声音输入和输出。
自升级到 KUbuntu 24.04.1 以来，此功能一直无法正常工作，而且我无法调试它，因为我不熟悉 pipewire 也不熟悉 pipewire-pulse“桥”。
插入 EPOS 加密狗后，切换无法正常进行：在 pavucontrol 中，EPOS 显示为默认源和接收器，但没有实际声音。我可以通过使用 pavucontrol 选择 NVIDIA GPU 作为默认设置，然后再选择 EPOS，使其正常工作。
有一次（在网络会议期间），我突然没有声音了。我通过在 pavucontrol 中执行相同的操作恢复了声音。但当我关闭 pavucontrol 时，它又出错了。然而，这并不是系统性发生的，而是随机发生的。
我认为我的配置对于从 22.04 升级到 24.04 来说非常标准。我所做的唯一更改是在/bin/true下创建了一个符号链接$HOME/bin/pulseaudio：这使游戏 (Victoria 3) 能够正确检测 NVIDIA GPU 声音接收器（否则它将输出到计算机机箱的内置扬声器）。
仅供参考，网络会议是在 Firefox 下使用 Big Blue Button 进行的（直接从 Mozilla 获得，而不是 snap distrib）。

我刚刚升级到 KDE 5.27.11，发现我最常用的自定义快捷方式之一无法再使用。
我曾经使用 Ctrl+Alt+Left 和 Ctrl+Alt+Right 在虚拟桌面之间垂直切换（这样我就不必记住我是要向上还是向下），但现在看来我需要将一个设置为向上，一个设置为向下，而当我已经在顶部/底部时，向上/向下移动什么也不做。
有没有办法让它像以前一样工作？例如：如果我在顶部桌面时点击“向上”，它就会前进到底部桌面。
我正在使用 Kubuntu，想管理登录时自动启动的应用程序。我已检查系统设置中的“自动启动”选项卡，但我刚刚安装了 AnyDesk，尽管它没有列在那里，但它会自动启动。
那么其他桌面 GUI 如 Ubuntu 或最省电的 Ubuntu Mate，它们的自动启动应用程序隐藏在哪里？
我将目录从旧的外部驱动器复制到新的外部驱动器，但我不知道字节数或位数是哪个，它们是不同的。在旧的驱动器中，dolphin 显示目录的大小为 782,3 GiB (839.945.943.248)，而在新的驱动器中，dolphin 显示目录的大小为 782,3 GiB (839.937.038.544)。两个驱动器中的文件和文件夹数量相同。这是正常的还是应该相同？这是一张图片：
左边的是旧驱动器，右边的是新驱动器。
要将图标分配到 KDE 菜单中相应的类别，*.desktop ($HOME/.local/share/applications/app.desktop) 文件中的哪个条目是必需的？我想使用 Bash 脚本来执行此操作，因此使用 KMenuEdit 应用程序对我来说不够。我创建的所有图标最终都丢失了。
我刚刚安装了 Kubuntu 24.04，默认主题非常明亮和白色，我试图选择更暗的主题，但所有主题（包括微风）似乎都不起作用。我进入系统设置，更改主题，点击应用，输入我的密码，然后重新启动。相同的主题，没有变化。
我能做些什么来修复这个问题吗？
编辑：如果我禁用自动登录，我可以调整主题。为什么会这样？
本周刚开始使用 Kubuntu (24.04)，并尝试设置好一切，我发现蓝牙检测不到任何设备（我尝试过将多个设备置于配对模式，这些设备在其他操作系统和我的 Android 手机上运行）。我已经找到了如何检查蓝牙服务的状态、获取设备信息的方法，一切似乎都很正常，驱动程序也正确，但我无法发现任何设备。任何有关尝试的建议都将不胜感激。
以下输出使我认为蓝牙服务和设备已启动并正在运行......

对我来说，这看起来像是设备正在工作、被发现、有驱动程序并且正确连接到蓝牙服务，而且我知道它在 Windows 上测试过后可以正常工作，但有些东西阻止它发现任何设备。任何建议都将不胜感激！
（注意：我不知道这是否相关，但正如所提到的，该系统与 Windows 是双启动的。作为解决 wifi 问题的一部分，我已经在 Windows 中禁用了快速启动。）
