Fixing Xmind on Debian 13

· 654 words · 2 minute read

写文档用 flatpak 版的 xmind 绘制脑图时发现，保存文件时，文件选择对话框一直跳不出来。自打升级到 Debian 13 Trixie 还没用过 xmind, 研究了一下。

先从控制台启动，这样可以方便的观察到错误日志：

$ flatpak run net.xmind.XMind

发现，报错为：

Failed to call method: org.freedesktop.DBus.Properties.Get: object_path= /org/freedesktop/portal/desktop: org.freedesktop.DBus.Error.InvalidArgs: No such interface “org.freedesktop.portal.FileChooser”

后来发现，之前的报错在 journalctl 中也有记录。

Google 搜索提示：

# If you are using another desktop environment (like GNOME or XFCE):
$ sudo apt install xdg-desktop-portal-gtk

# Check if xdg-desktop-portal is running
$ systemctl --user status xdg-desktop-portal

# 检查接口是否存在（来自：Qwen3-Max）
$ gdbus introspect --session \
  --dest org.freedesktop.portal.Desktop \
  --object-path /org/freedesktop/portal/desktop \
  --xml | grep org.freedesktop.portal

根据提示进行检查，得到结果：

  1. xdg-desktop-portal-gtk 确实已经安装；
  2. xdg-desktop-portal 确实已经运行；
  3. gdbus 的输出确实也没有 FileChooser.
$ gdbus introspect --session \
  --dest org.freedesktop.portal.Desktop \
  --object-path /org/freedesktop/portal/desktop \
  --xml | grep org.freedesktop.portal                                       
  <interface name="org.freedesktop.portal.Trash">
  <interface name="org.freedesktop.portal.MemoryMonitor">
  <interface name="org.freedesktop.portal.GameMode">
  <interface name="org.freedesktop.portal.ProxyResolver">
  <interface name="org.freedesktop.portal.Inhibit">
  <interface name="org.freedesktop.portal.Secret">

  <interface name="org.freedesktop.portal.PowerProfileMonitor">
  <interface name="org.freedesktop.portal.Email">
  <interface name="org.freedesktop.portal.Realtime">

再次检查 xdg-desktop-portal 的运行情况。发现虽然服务在运行，但是有报错信息：

systemctl --user status xdg-desktop-portal
● xdg-desktop-portal.service - Portal service
     Loaded: loaded (/usr/lib/systemd/user/xdg-desktop-portal.service; static)

             └─2633 /usr/libexec/xdg-desktop-portal

于是尝试重启该服务：

$ systemctl  --user restart xdg-desktop-portal-gnome.service
Failed to restart xdg-desktop-portal-gnome.service: Unit xdg-desktop-portal-gnome.service is masked.

见招拆招：

$ systemctl --user unmask xdg-desktop-portal-gnome.service
Removed '/home/david/.config/systemd/user/xdg-desktop-portal-gnome.service'.
$ systemctl --user restart xdg-desktop-portal.service                                  
$ systemctl --user status xdg-desktop-portal

很好，这回 xdg-desktop-portal 服务没有报错。再次测试：

$ gdbus introspect --session \
  --dest org.freedesktop.portal.Desktop \
  --object-path /org/freedesktop/portal/desktop \
  --xml | grep org.freedesktop.portal
  <interface name="org.freedesktop.portal.Inhibit">

再次运行 xmind, 果然正常了。
