How to disable GUI on armbian (revert the Desktop to server)

  1. Check which Display manager that you're using currently
    cat /etc/X11/default-display-manager
    nodm should be default if you're choose auto login when setting by armbian-config
    but you're change it with lightdm or sddm, so check the display manager first.

  2. Disable current display manager
    if you're using nodm
    sudo systemctl disable nodm
    if you're using lightdm
    sudo systemctl disable lightdm
    if you're using sddm
    sudo systemctl disable sddm

  3. Reboot the system
    sudo reboot

  4. It's should be great now~

忘記哪來的喇叭,好像是我哥給的,時間已經不可考 最初給我的時候應該是圖片中的擴大器異常,已經忘記是不過電還是音量控制有問題啥的 (剛才查這顆喇叭發現可能是通病,有一些文章有提到長時間使用後,音量的可變電阻可能會不正常) 我已經忘了當初檢修的過程,或是有沒有修了 最後我放棄那個擴大...
