If You’re Archlinux install is causing the monitor to timeout and go blank after a short period (600 seconds default) and u find it a pain as there is no power management to disable it in some WM’s, here is what we do to disable the monitor timeouts …
1. pacman -S xorg-xset
(User preference utility for X)
2. add these commands to execute at boot (.xinitrc) i find using only A&B suffice.
a. xset s off
b. xset -dpms
c. setterm -blank 0 -powerdown 0
or you can add above commands (abc) in terminal (not as root) before you want to kick back and watch a movie without the screen timing out.
check config with xset -q
will not work as root
