Solved How to set blank time

[balanga]

How to set the period before the screen goes blank?

I'm using LXDE if that is relavant?

 

[Maturin]

xset s 300 to set it to 300 seconds = 5 minutes
xset s default to set it back to what's written in your X config

How do I tell what it is currently set to?

I'm not using LXDE, but misc/lxde-common, which should be a part of LXDE, depends on x11/xscreensaver for run.
So doesn't xscreensaver-settings(1) included in x11/xscreensaver work for it?

xset q

xset q

What sets this value initially?

Does that happen when installing xorg?

 

[balanga]

xset q

This works on one of my laptops. On another I get:-

xset q

unable to open display ":0"

xset q

unable to open display ":0"

Anyone know what this means?

It usually means that you have tried to run a Xorg command from a shell which was not started from Xorg (like a console terminal). Xorg sets the DISPLAY variable, like this

tingo@kg-core2:~ $ echo $DISPLAY
:0.0

If I do the same from a root shell

root@kg-core2:~ # echo $DISPLAY
DISPLAY: Undefined variable.

In your specific case, it means that it tries to open display ":0", but it doesn't exist on that machine. Try to check the DISPLAY variable and see what it is set to. Note: ":0" and ":0.0" are different displays.

 

[T-Aoki]

If your DISPLAY environment variable is set to :0.0, try xset -q -display :0.0.

The default is the DISPLAY environment variable.
XOpenDisplay(3)

On a POSIX-conformant system, if the display_name is NULL,
it defaults to the value of the DISPLAY environment variable.
