Can the screensaver be activated by a keypress to blank the screen immediately?

I asked this in the Wary thread, but it mustn't be sufficiently technical to prompt anyone to answer. Confused

Wary doesn't have a MENU entry for the screensaver. I think older puppies did.

I'm sure screensaver isn't too hard.

But Im not sure what screen saver wary uses, so i cant help you there.
Instead, let me suggest this:

You could keybind this command to a key
Quote:
xlock -mode blank


But thats not screensaver you need to key in your password instead of just moving your mouse.

If might be better than a screensaver depending on what you want this keybind for...


Do you use openbox or jwm or icewm or...?

Screensaver in Wary:

Shep, do you mean you want to go to suspend mode?
The title of your post indicates screensaver.

I'd like to make the screen go blank with the press of a key, in addition to it going blank after 10 mins of inactivity. I don't want to suspend processing.

So calling the screensaver with a blank image, prepared in advance.
I am not sure however if the back-light is cut-off.

Maybe acpitool has an option for this.

You probably want to create a JWM keybinding to run the xlock command.
For example, Alt+Esc (this goes in ~/.jwm/jwmrc-personal):
Code:
<Key mask="A" key="Esc">xlock `cat /root/.config/Xlock/xlockscreenparams`</Key>

That file doesn't exist, at the moment. Your Xlock suggestion might be ideal, because I would use its option to not mess with passwords:
Code:
+/-nolock
  The nolock option causes xlock to only draw the patterns and not lock the display. A key press or a mouse click will terminate the screen saver.

I just want to blank the computer screen so I can more easily view the tv screen over the top of it.

Shep,

I think I had a little problem along activating a screen blank with a key press. I think I worked around it with a script and sleep for a split fraction of a second.

That's strange... if JWM is used that file should exist since it's what the configuration utility changes (and has some default settings).
You should look in ~/.jwmrc for Include lines like:
Code:
 <Include>/root/.jwm/jwmrc-personal</Include>

which should tell you where it is... (you could just add the keybinding to jwmrc, but it will disappear when it gets regenerated)

There is no /root/.jwmrc
The only files in /root/.jwm are jwm_colors jwmrc-personal jwmrc-personal2 jwmrc-theme themes
There are no hidden files. The two personal files seem identical.

Code:
# find / -name 'xlockscreenparams'
#

When I put your alt esc idea into one of the personal files, it doesn't fire off xlock. When in a console the ALT-ESC combo produces:
Code:
display all 1493 possibilities? (y or n)

To specify a control key, do I use "C"? Is shift "S"?
What about the windows key, how do I specify it?

For the windows key, it should be mod4

so you can use the number 4 like:
<Key mask="4"

Well, the "personal" files are what I mentioned in the first place: that's where you add the new keybinding.
If there's no /root/.jwmrc then you must not be using JWM...

The xlockscreenparams file is created when you configure xlock... I just looked at Barry's xlock_gui package and it still seems to use it.
