我正在尝试运行多用户远程桌面隔离模式，每个会话都运行自己的 kde 实例。目前，我已经配置了 lightDM 并运行 VNC 服务器。我可以毫无问题地运行 Xfce，但 Kde 在启动时崩溃。此外，我无法从 Xfce 运行 OpenGL（glxinfo 未找到任何内容并显示没有 RGB 显示）。
这是“不完整”的 kde 启动画面回溯

我有 Kubuntu 19.10 eoan ermine。我在主机上使用 AMDGPUpro 20.10 预览视频 (R9Fury)（本地用户工作得很好）。最终的“目标”是让 kdenlive 运行（特别是 mp4 硬件编码），这样其他人就可以从外部编辑视频，而这台计算机可以渲染，而我则在我的会话中做其他无聊的事情。我现在正在下载符号以尝试调试它，但我认为问题更“微妙”，只是远程服务器找不到 libGL。
