从 Kubuntu 24.10 (oracular) 更新到 Kubuntu 25.04 (plucky) 后，登录屏幕坏了：
- 背景是白色的，而不是通常的壁纸
- 屏幕下半部分是一个巨大的可视键盘（可以隐藏起来）
- 屏幕中间显示默认用户图片，其下方是密码文本字段
- 输入密码并按下回车键不会打开用户会话
- 用于选择会话的下拉菜单位于左上角
- 用于选择会话的下拉菜单没有条目
因此无法使用 SDDM 登录 Plasma 桌面环境。
在 24.10（Plasma 6 - 包括将服务菜单文件位置更改为~/.local/share/kio/servicemenus）之前，我已经能够添加自定义服务菜单，以便使用各种程序，如 Thunar 重命名器或 Catfish 搜索。
例如，.desktopThunar 批量重命名器的“定制服务”文件是：
[Desktop Entry]
Actions=BulkRename;
Icon=edit-rename
MimeType=all/all;
ServiceTypes=KonqPopupMenu/Plugin
Type=Service
X-KDE-Priority=TopLevel
X-KDE-StartupNotify=false
[Desktop Action BulkRename]
Exec=thunar -B %U
Icon=org.xfce.thunar
Name=Bulk Rename
但是现在这样的操作会出现这个错误：
我是 Linux 新手。几天前我刚从 Windows 转过来，所以我还在弄清楚一些事情。我使用的是 Kubuntu 24.04.1（最新 LTS 版本）。
我想在桌面上添加一个应用程序小部件，但这个小部件只包含我的游戏列表。不幸的是，我删除了除“游戏”子菜单之外的所有子菜单。我没有意识到 KDE 菜单编辑器不仅会影响这个单独的小部件，还会影响任务栏中的应用程序启动器小部件。请帮助我恢复其他子菜单并将应用程序启动器重置为正常！
我的应用程序启动器在我意外删除了它的所有子菜单后被毁了（现在唯一的子菜单是“游戏”：
我使用 KDE 菜单编辑器删除了除“游戏”之外的所有子菜单，因为我认为这只会影响桌面上的一个小部件：
我的妻子不久前买了这台笔记本电脑，但蓝牙从未在 Kubuntu 上工作过。蓝牙管理器似乎在工作，但从未检测到蓝牙设备。其他设备也无法检测到这台笔记本电脑。我已经执行了以下查找故障的步骤，但未能纠正故障：

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？
