我通过 SSH 和 X-forwarding 连接到 OpenSUSE Leap 42.2。除了以下情况外，系统完全处于全新状态（“服务器”选项）
- sshd 已启用
- 安装
kde-cli-tools-5以获得kdesu - 安装
dolphin和konsole
我能够使用 kdesu启动konsole和之类的应用程序，但是，当我运行 时，在出现的提示中输入密码后，没有出现 YaST 窗口。我的命令执行后控制台中没有任何内容出现，日志如下：dolphinkdesu yast2
sudo cat /var/log/YaST2/

什么原因导致出现任何 GUI 的静默故障？是否还有其他需要安装的软件包，或者可以检查其他日志？
答案1
为什么要通过 SSH 连接使用 YaST GUI？yast当在命令行中调用而不使用 x-forwarding 时，将使用 ncurses 在终端窗口中绘制一个界面。它对调整大小等非常友好。
它具有 GUI 的所有功能，并且组织方式相同。
