我有一台内置 KVM 的 Dell U3821DW 显示器。我在 Windows 上安装了 Dell Display Manager，并配置了一个快捷方式来在输入源之间切换。我想在 Ubuntu 中有一个快捷方式来执行相同操作，但 Dell Display Manager 无法在 Linux 上运行。还有其他方法可以实现吗？最好运行某种使用 KVM 标准协议的本机实用程序，而不是在 Wine 中运行 Dell Display Manager。谢谢。
我找不到如何在戴尔笔记本电脑上禁用 TouchGuard/DisableTouchpadWhileTyping。
我使用的是 Ubuntu 23.10。
我的 Dell XPS 9700 和 Ubuntu 23.04 经常遇到一个问题：CPU 温度升至约 60°C，导致风扇发出烦人的声音。CPU 上没有明显的负载可能导致这种情况 - 至少据我所知。sensors下面是显示问题的输出。
这个问题是在之前的安装中出现的，这就是我全新安装 Ubuntu 23.04 的原因。对我来说幸运的是，这解决了大约两周的问题。现在我又回到了原点。
我在之前的安装中尝试的是使用 i8kmon 等工具来“微调”风扇速度，但这只会导致系统振荡（温度和噪音方面）。我知道这台笔记本电脑在空闲条件下能够承受相当低的温度。所以一定有什么事情发生...
我可以做什么来诊断这个问题？我需要提供什么信息吗？

我在戴尔 XPS 9510 上运行带有最新更新的 Ubuntu 20.04，电池性能真的很差。在轻度使用（仅在简单网站上浏览网页）的情况下，我的电池续航时间最长约为 1 小时 30 小时，而在 Windows 下，笔记本电脑可以轻松达到 8 小时。差异是巨大的。
我检查了很多设置并安装了 TLP 以提高电池寿命而没有进行重大更改，但是我观察到一个奇怪的行为可能解释了这种高消耗。当核心处于空闲状态时，核心在负载下正确扩展时，频率会回到标称速度 (2,5Ghz) 而不是最低速度 (800Mhz)。
以下是一些输出：

我最近买了一台带有 ubuntu 20.04 的 Dell Precision 3450，并分两步升级到 ubuntu 21.10（20.04 -> 21.04 -> 21.10）。这需要手动升级文件/usr/lib/os-release，如此处所述，可能是因为戴尔对 OEM 安装进行了自定义。
无论如何，系统现在工作正常，只有一个例外。当我输入curl终端（我在第二次升级后安装的）时，我收到以下错误消息。
curl：加载共享库时出错：libldap_r-2.4.so.2：无法打开共享对象文件：没有这样的文件或目录
所以似乎 curl 正在尝试在未安装的 2.4 版中加载 libldap。我问了一个朋友，他也有 ubuntu 21.10，并且在(7.74.0-1.3ubuntu2) 和(2.5.6+dfsg-1~exp1ubuntu1)curl的相同版本下工作正常。curllibldap
我还尝试安装旧版本的 libldap - 特别是libldap-2.4-2_2.4.57+dfsg-2ubuntu1_amd64.deb来自 21.04 repo 的文件 - 但在这样做之后，curl给了我一个新的错误消息：
curl：符号查找错误：curl：未定义符号：curl_multi_poll，版本 URL_OPENSSL_4
所以这没有帮助。
有人知道发生了什么吗？
我不明白动态链接是如何工作的，谷歌搜索并没有真正帮助。该网站建议简单地做sudo /sbin/ldconfig -v，但没有奏效。
我不知道问题是否特定于 ubuntu 的 OEM 安装和“强制”ugprade，但令人惊讶的是，除此之外的一切curl似乎都有效。

如何解决这些问题并成功安装该工具？
我有运行 Ubuntu 21.04 的 XPS 15 (9510) 通过左侧站点上的一个 Thunderbolt 4 端口连接到电源，偶尔我连接到笔记本电脑的右侧 (USB-C)，这是一个小型底座，也通过USB-C PD（需要操作扩展坞），有2个电源，会损坏笔记本电脑吗？或者笔记本电脑将继续只使用 TB4（当我插入扩展坞时它已经处于活动状态）并放弃扩展坞提供的电源？谢谢
我只是在实时模式下运行 Ubuntu 21.04 进行测试，然后在具有 OLED 屏幕的 XPS 15 9510 上进行完整安装，但我无法控制屏幕亮度，我知道多年前的 OLED 屏幕存在问题，但我想这一点已经解决了。戴尔通过终端提供了一个临时的解决方法，但不是很实用：
关于如何解决这个问题的任何建议？谢谢
我提出这样的问题是因为我也在寻找一些一般性的建议，除了可能是这个问题的技术解决方案。
只是用火狐浏览（打开一百万个标签），计算机最终冻结，我可以移动光标，但没有别的。top我重新启动了计算机，并在角落里留下了一个带有监控的终端。当它再次发生时，kswapd0正在使用 99% 的 CPU。我拍了一张冻结屏幕的照片：
kswapd0我想我从这个不错的答案中明白了什么。
问题：我应该尝试应用@Zzzach 的建议......并尝试一下，还是 ubuntu 崩溃的事实指向一个更根本的问题？更实际的是：我应该退回我的新笔记本电脑并再买一台（也许有更多的内存）？
现在任何建议都会对我有用。谢谢你。
DELL Precision 3551（8Gb，i7-10 代，6 核）。直接买给DELL。预装 Ubuntu 20.04
