HOWTO Invert X colours on the fly

[GustavoYz]

Two steps.
1- Install xcalib (maybe newer puppies have it, not sure).
2- Find a way of bind it to a keyboard shortcut.

1- Easy, install the pet below.
2- In OpenBox, you need to add something like this to your rc.xml:

Code: Select all

<keybind key="C-A-i">
      <action name="Execute">
        <startupnotify>
          <enabled>true</enabled>
          <name>Colorines</name>
        </startupnotify>
        <command>xcalib -invert -alter</command>
      </action>
    </keybind>

Add it after:

Code: Select all

<!-- Keybindings for running applications -->

and dont interrupt any previous entry (between the 'keybind' tags).
Then just restart X and try it out.
For others wm, search here.

*It works for me, as I tend to use black themes, to read from the screen when is a bare light.
Enjoy.

Is there an missing link/url?

Nice , works on Puppy 4.3.1 ..

Will have to make a script and a button for that ..

Nice , works on Puppy 4.3.1 ..

your screengrab, "xcalib.png", doesn't appear inverted (negative) to me,
the attachment may appear inverted on your computer, but not on mine ...

Hi, gustavo.

Same question as harii4: where do we search to make this work with other wm's?

Thanks in advance.

Hi all.
In first place, you invert monitor colours, so the screencap will not show it, but it looks exactly as Karl Godt's doctored screencap shown.
I meant this link (Patriot's about shortcuts jwm).
Feel free to post other ways in other wms.

All is about make 'handy' the command:

Code: Select all

xcalib -invert -alter

somehow.
I used OpenBox's configs for that.
Sorry for the confusion.

BETTER ?

Yes: that 2nd version of xcailib.png appears inverted on my computer.

I have just inverted the colors of the screenshot in mtpaint . This does exactly the same as xcalib does .

Did not realize this behaviour .

Its like dark sunglasses on the surface of the screen , but everything underneath of it stays as before .
