有時候linux系統是沒有圖形化介面的，為了關閉鎖屏和息屏可以用如下命令

關閉息屏，最後0是代表關閉鎖屏，將0替換為60代表60s後自動息屏，以此類推。
gsettings set org.gnome.desktop.session idle-delay 0


關閉鎖屏
gsettings set org.gnome.desktop.screensaver lock-enabled false

If you want to wrap your app in a script that takes care of this for you when you launch it (or GUI simply isn't an option), the best command-line solution as of Ubuntu 14.04 is:

To disable the screen blackout:

gsettings set org.gnome.desktop.session idle-delay <seconds> (0 to disable)

To disable the screen lock:

gsettings set org.gnome.desktop.screensaver lock-enabled false

You probably want to add their inverses at the end of the wrapper script to return your system to normal behavior on exit. In such a case, you want to prevent against ungraceful termination (i.e. interrupt, or SIGTERM during system shutdown), so create a function to restore normal behavior and use trap <function> 0
