Ubuntu 22.04.3 LTS（GNOME 42.9）下普通用户调用notify-send报错，notification-daemon启动触发段错误求助

大家好，我已经看过另外两篇描述相同问题的帖子，但里面提到的解决方案对我都没用，所以来这里求助。

我的环境 #

• 系统：Ubuntu 22.04.3 LTS
• 桌面环境：GNOME 42.9

问题详情 #

我现在遇到的核心问题是，普通用户身份执行notify-send会报错：

robin@robin-workstation:~$ notify-send "test"
Error calling StartServiceByName for org.freedesktop.Notifications: Process org.freedesktop.Notifications received signal 11

看起来当时没有相关的通知进程在运行，所以系统尝试启动org.freedesktop.Notifications服务，但启动失败触发了段错误（查了下signal 11对应的就是段错误）。

我手动启动notification-daemon的时候，确实直接触发了段错误：

robin@robin-workstation:~$ /usr/lib/notification-daemon/notification-daemon
Segmentation fault

有意思的是，用sudo以root身份启动这个程序的话，终端会直接挂起，但进程列表里能看到它在运行，不过此时执行notify-send还是报同样的错：

robin@robin-workstation:~$ ps aux | grep notification
robin       2262  0.0  0.0 250308 11892 ?        Ssl  14:42   0:00 /usr/libexec/gsd-print-notifications
root        7254  0.2  0.0  14268  5700 pts/0    S+   15:27   0:00 sudo /usr/lib/notification-daemon/notification-daemon
root        7255  2.4  0.1 263632 22144 pts/0    Sl+  15:27   0:00 /usr/lib/notification-daemon/notification-daemon
robin       7268  0.0  0.0   9216  2276 pts/2    S+   15:27   0:00 grep --color=auto notification

robin@robin-workstation:~$ notify-send "test"
Error calling StartServiceByName for org.freedesktop.Notifications: Process org.freedesktop.Notifications received signal 11

已排查/尝试的操作 #

• 确认没有安装notify-osd（我的机器上没装这个）
• 确认libnotify-bin和notification-daemon都是最新版本：

robin@robin-workstation:~$ sudo apt install notification-daemon
notification-daemon is already the newest version (3.20.0-4build1).

robin@robin-workstation:~$ sudo apt install libnotify-bin
libnotify-bin is already the newest version (0.7.9-3ubuntu5.22.04.1).

• 检查了DBus服务文件的内容，看起来是正常的（问题应该不是找不到服务，而是启动时段错误）：

robin@robin-workstation:~$ cat /usr/share/dbus-1/services/org.freedesktop.Notifications.service
[D-BUS Service]
Name=org.freedesktop.Notifications
Exec=/usr/lib/notification-daemon/notification-daemon

• 尝试重新安装notification-daemon和libnotify-bin，没有效果
