我有 XPS 15 的 2022 型号，并且安装了 Ubuntu 22.04（带有内核 5.19 来解决音频问题）。
我在挂起和休眠方面遇到了一些不同的问题（这是必需的，因为硬件仅支持 s2idle 并且它会非常快地耗尽电池电量 - 根据其他帖子，我已经从 RAID 更改为 ACHI）。
第一个问题：挂起似乎不会让系统进入远程低功耗状态 - 如果我让笔记本电脑在挂起状态下过夜，电池将会完全早上死机了 - 挂起时耗电量似乎和唤醒时一样多。我检查过，当我合上盖子时，它进入挂起状态（通过 dmesg 和 journalctl）。
第二个问题：我设置了暂停然后休眠来解决这个问题 - 它似乎试图进入休眠状态（从 journalctl），但是没有实际上处于休眠状态 - 早上笔记本电脑仍然很热，当我打开它时，键盘和屏幕背光立即亮起（尽管机器随后挂起）。
一些细节：系统有 32GB RAM 和 40GB 交换空间（几乎从未使用过）。磁盘使用 luks 加密，包括根分区和交换分区（在同一个 luks 中，我认为这可能会给我带来麻烦，但一步一步来）

我在笔记本电脑上运行 docker（有时运行容器，有时不运行），除此之外，我没有运行任何特别有趣的东西
从进入挂起状态直到我重新启动（昨晚到今天早上）时 journalctl 的输出。

答案1
我在使用 s2idle 时也遇到了类似的问题。我的解决方案是设置
/sys/module/acpi/parameters/ec_no_wake
到
Y
答案2
这不是一个真正的答案，但我重新安装了 Ubuntu，并且全部我的问题从低音扬声器不工作的问题开始消失了。
现在暂停功能可以正常工作，每小时消耗大约 1% 的电量，休眠功能“可以正常工作” - 包括电池几乎没电时自动休眠（这是一个不错的惊喜）。
我现在已经重新安装了之前运行的所有程序（我以为可能是 docker 或指纹识别器导致了我的问题，但事实并非如此 - 一切都正常）
重新安装时我只做了两件不同的事情：
- 我选择了“安装更新”选项
- 我在安装过程中确保有足够大的交换分区用于休眠，而不是稍后添加。使用全盘加密时，这比听起来要难，因为安装程序不提供指定交换大小的选项，但是会弹出一个小模式询问您是否确定要进行更改，此时您可以打开 gparted 并将 1GB 交换分区的大小调整为您想要的大小
