Debian 消息中心界面优化指南
一 现状与定位
二 优化路径总览
三 方案一 使用 Dunst 优化通知外观与行为
sudo apt install dunst libnotify-binexport XDG_CURRENT_DESKTOP=GNOME; dunst &(按你的实际会话替换;GNOME 默认使用 gnome-shell 自带的通知服务,需先停用或替换后再用 Dunst)。geometry = 380x60-10+40(宽度、最大高度、水平/垂直偏移)corner_radius = 8、padding = 10、horizontal_padding = 15font = "Noto Sans CJK SC 10"(支持中文)transparency = 10、frame_width = 1、frame_color = "#aaaaaa"timeout = 6(秒)history_length = 20、show_age_threshold = 60group_by = sender、merge_level = similarurgency_low = { background = "#222222"; foreground = "#888888" }urgency_normal = { background = "#285577"; foreground = "#ffffff" }urgency_critical = { background = "#992222"; foreground = "#ffffff"; timeout = 0 }[spotify] summary = "Spotify" appname = "Spotify" urgency = low[apt] appname = "APT" set_transient = true skip_display = true(将 APT 提示静默,交由 update-notifier 托盘图标呈现)notify-send "Test" "Hello Dunst";必要时 killall dunst && dunst & 重载。四 方案二 使用 Linux Notification Center 获得集中式界面
sudo apt-get install gtk3 gobject-introspection-runtimewget https://github.com/phuhl/linux_notification_center/releases/download/1.7.2/linux_notification_center-1.7.2.tar.gz
tar -xvzf linux_notification_center-1.7.2.tar.gz
cd linux_notification_center-1.7.2
sudo make install
deadd-notification-centerwidth: 500px;)。notify-send "Hello" --hint boolean:deadd-notification-center:true五 系统级消息源与登录提示优化
sudo apt install update-notifier(GNOME 常见)。echo 'APT::Periodic::Unattended-Upgrade "1";' | sudo tee /etc/apt/apt.conf.d/10periodicpam_motd 脚本或 update-motd 机制输出系统状态摘要,避免冗长输出。tail -f /var/log/boot 或 egrep -iw 'err|warn' /var/log/boot,将关键告警收敛为桌面通知(通过脚本 + notify-send)。六 常见问题与排查
XDG_CURRENT_DESKTOP 与会话一致。use_system_font = false。geometry 的偏移与最大高度;必要时设置 layer = overlay 或 placement = bottom-right。APT::Periodic::Update-Package-Lists 频率。
