Screen goes blank after ten minutes (in LXDE), how to change this?

I'm using LXDE on Arch, and the screen blanks after ten minutes of inactivity. I'm not sure if it's screensaver or power management. How do I change this behaviour?

Probably your screensaver. Check settings

I don't know where the screensaver settings are though. I search for 'screensaver' on the Arch Wiki and didn't find anything that seemed relevant.

It's X

X itself puts on this screensaver by default. You can check this with xset q. To disable, type

bash:$ xset s off

X also automatically puts your pc in standby after 20 minutes or something, and it puts it into hibernate after 30. It would turn it off after 10 more minutes if it could. To disable this too, type:

bash:$ xset -dpms

You can do this automatically when you log in successfully by putting these lines in ~/.xsessionrc:

robo@anonymous:~$ cat .xsessionrc
# turn off default screensaver
xset s off
# turn off default standby, hibernate, ... after n minutes
xset -dpms

The screen still goes blank after 10 minutes before you login, in gdm. But that doesn't bother me.

This was probably put in because of people with old monitors, that can have images burnt in to them. Or for energy saving purposes. Still a pain in the ass, though.

You can put it in Xorg.conf too :

it's 2010 but hopefully it saves time to somebody else.

xset s noblank
and make sure your screensaver doesn't kick in until 10 hours later or simply disable it.

Try running xscreensaver-demo. If your system is using xscreensaver, it will let you configure the screensaver itself and power management.
