問題

• 無法調整解析度

  因為沒有實體顯示器，套用預設設定 (opens new window) 800x600

• 卡成狗
• 如果強迫建立新的 Session, Client 連線後出現錯誤訊息

解決方法

• [ ] How to run a virtual desktop environment on Linux different from the default one with NoMachine (opens new window)

  沒有用，本來 DefaultDesktopCommand 就已經預先設置正確

• [x] Add Fake Display when No Monitor is Plugged In (opens new window)

  新增一個 FHD 的虛擬顯示器
