==== laptop suspend 시에 system down ====
  * laptop 뚜껑을 닫았을 때 suspend 되게 해두면, 다시 뚜껑을 열었을 때 제대로 살아나지 못하고 죽는 현상이 발생했음.(X11, Gnome)
  * [[linux:laptop|Linux &amp; Laptop(Notebook)]] 참조하여 suspend 되지 않고 그냥 전원 유지하게 변경함.

<code sh>
gsettings set org.gnome.settings-daemon.plugins.power lid-close-ac-action 'nothing'
gsettings set org.gnome.settings-daemon.plugins.power lid-close-battery-action 'nothing'
gsettings set org.gnome.settings-daemon.plugins.power sleep-inactive-battery-type 'nothing'
