WM 下 Dolphin 的前景色可能会很奇怪，在 .config/dolphinrc 中添加以下内容可以解决：
```conf
[UiSettigs]
ColorScheme=<name>
```
例如<s>大家都喜欢的</s>猫布奇-抹茶-蓝
```conf
[UiSettigs]
ColorScheme=Catppuccin Mocha Blue
```
colorscheme 名(大概)可以在 `~/.local/share/color-schemes/`下的文件中查看。

虽然不是很确定发生了什么，但总归记录一下
问题：
休眠后立即唤醒
环境：
hyprland (kde 下无此问题)
hybrid (独显直连没有测试)
结论：
罗技 Bolt 接收器导致的
解决1：
修改 /proc/acpi/wakeup 禁用 usb 唤醒
修改什么？问 LLM 吧，现在的我也不知道 :)
解决2：
安装 solaar 并启动
步骤：
创建 plugdev 用户组：
sudo groupadd plugdev
sudo usermod $(whoami) -aG plugdev
安装 solaar
启用驱动：
sudo modprobe hid_logitech_dj
重载 udev 规则：
sudo udevadm control --reload-rules
插拔 Bolt 接收器
启动！

当安装了其他 notification manager 时，plasma 在启动时可能会选择错误的 notification manager 导致通知中心无法正常工作 <s>(虽然平时也并不怎么在意这玩意，用什么 daemon 都无所谓，只要有通知看就行)</s>
如何知道是否是这种情况呢？以 mako 为例：
1. 先知道 mako 是什么时候被启动的 (或者自己推算时间)：
```sh
journalctl --user -u mako.service --no-pager -g 'Starting'
```
2. 查看先后的日志：
```sh
journalctl --user --since '2025-07-29 00:43:16' --until '2025-07-29 00:43:18'
```
3. 如果发现类似以下内容：
```
...
Jul 29 00:43:17 Artemisia systemd[1080]: Starting Lightweight Wayland notification daemon...
Jul 29 00:43:17 Artemisia systemd[1080]: Started Lightweight Wayland notification daemon.
...
Jul 29 00:43:17 Artemisia plasmashell[1599]: org.kde.plasma.notificationmanager: Failed to register Notification service on DBus
...
```
那就是这种情况了。
解决方法也很简单，启动时屏蔽掉错误的服务，例如：
```sh
systemctl --user mask mako.service
```
或者将 plasmashell 的 notificationmanager 优先级提高：
```sh
mkdir -p ~/.local/share/dbus-1/services/
ln -s /usr/share/dbus-1/services/org.kde.plasma.Notifications.service ~/.local/share/dbus-1/services/org.kde.plasma.Notifications.service
```

## 登陆 shell
登陆 shell 是指用户通过终端登录系统时启动的 shell，通常是用户登录时执行的第一个 shell，可以通过`grep "^$(whoami):" /etc/passwd`查看。
登陆 shell 为 bash 时，在登陆时会检索
- `/etc/profile`
并加载，并会加载以下第一个存在的用户配置文件：
- `~/.bash_profile`
- `~/.bash_login`
- `~/.profile`
所有全局环境变量以及其他非交互配置（如 ssh-agent）都可以写进这些文件。
## 非登陆 shell
非登陆 shell 是指用户在已经登录的情况下启动的 shell，通常是通过终端仿真器或其他方式打开的 shell。
非登陆 shell 为 bash 时，会先加载`/etc/bash.bashrc`，然后加载用户的`~/.bashrc`文件。
对于非登陆 shell 为 fish 的情况，则会先加载`/etc/fish/conf.d`以及`/etc/fish/config.fish`，
然后加载用户的`~/.config/fish/conf.d`以及`~/.config/fish/config.fish`。
非登陆 shell 会继承登陆 shell 的环境变量，但不会加载登陆 shell 的配置文件。
## 当前做法
桌面端将登陆 shell 设置为 bash，对于终端模拟器显式指定 shell 为 fish，并禁用 conf.d 目录下的配置文件。
服务器端同样将登陆 shell 设置为 bash，并在.bashrc 中启动 fish，同样不使用 conf.d 目录下的配置文件。

在 btrfs 分区下使用 swapfile 创建虚拟内存 (复杂方法)：
1. 创建 swap 子卷 (假定已经挂载到 /mnt)：
```bash
btrfs subvolume create /mnt/@swap
```
2. 创建 swap 文件：
```bash
touch /mnt/@swap/swapfile
```
3. 禁用 COW：
```bash
chattr +C /mnt/@swap/swapfile
```
4. 设置 swap 文件大小（例如 16GB）：
```bash
dd if=/dev/zero of=/mnt/@swap/swapfile bs=1M count=16384 oflag=direct
# 可检查属性，确保有 C：
lsattr /mnt/@swap/swapfile
```
5. 设置 swap 文件权限：
```bash
chmod 600 /mnt/@swap/swapfile
```
6. 启用 swap 文件：
```bash
mkswap /mnt/@swap/swapfile
swapon /mnt/@swap/swapfile
# 可检查 swap 状态
swapon --show
```
7. 修改 `/etc/fstab` 以自动挂载 swap 文件：
```conf
UUID={btrfs-uuid} /swap btrfs rw,noatime,ssd,discard=async,space_cache=v2,subvol=/@swap 0 0
/swap/swapfile none swap sw 0 0
```
