安装的XMind 命令行启动也会报：
cmd@TR:/opt/xmind/XMind_amd64$ XMind
Gtk-Message: 16:16:57.274: Failed to load module "unity-gtk-module"
Gtk-Message: 16:16:57.525: Failed to load module "unity-gtk-module"
搜 ubuntu 18.04 failed to load module unity-gtk-module 搜到
发现有提到unity-gtk3-module 于是：
尝试安装 unity-gtk2-module unity-gtk3-module
cmd@TR:/opt/xmind/XMind_amd64$ sudo apt install unity-gtk2-module unity-gtk3-module
正在读取软件包列表... 完成
正在分析软件包的依赖关系树
正在读取状态信息... 完成
将会同时安装下列软件：
libunity-gtk2-parser0 libunity-gtk3-parser0 unity-gtk-module-common
下列【新】软件包将被安装：
libunity-gtk2-parser0 libunity-gtk3-parser0 unity-gtk-module-common unity-gtk2-module unity-gtk3-module
升级了 0 个软件包，新安装了 5 个软件包，要卸载 0 个软件包，有 0 个软件包未被升级。
再行尝试启动上述appium-desktop或xmind完美解决 failed to load module unity-gtk-module 命令行启动的话启动日志不会报该错了。
另外，加说些内容 目前18.04 解压zip形式安装的xmind8
无法正常生成启动desktop文件，需要自己添加.desktop 。
我是个人习惯安装到了/opt/目录下，unzip xmind-pro-8-linux.zip -d /opt/xmind。
sudo gedit /usr/share/applications/xmind.desktop 或者 ~/.local/share/applications 都可以。
内容：
[Desktop Entry]

注意给下权限sudo chmod 755 xmind.desktop
自己搜索 xmind icon 128x128 找一个差不多的放入路径/opt/xmind/ 即可。
