[RPi] Disable Screen Blanking in X Window

如果想要把Raspberry Pi當作展示機, 那Raspbian預設10分鐘沒動作畫面就會暗掉就蠻令人困擾的, 通常修改xinitrc就會有作用

$ sudo vi -p ~/.xinitrc /etc/X11/xinit/xinitrc

xset s off         # don't activate screensaver
xset -dpms         # disable DPMS (Energy Star) features.
xset s noblank     # don't blank the video device
exec /etc/alternatives/x-session-manager      # start lxde

如果再不行的話就要再lightdm.conf新增一個屬性了

$ sudo vi /etc/lightdm/lightdm.conf

[SeatDefaults]
xserver-command=X -s 0 -dpms
