[Lubuntu] Change default screenshot format

This is about changing scrot’s default screenshot format from PNG to JPEG. The main reason for doing so is to save space, though the quality is a bit lost.. Anyways, the solution was found on this Ubuntu thread (Glutanimate’s solution for more detail).

 

Modifying image format

Making a backup of the original configuration file:

cp ~/.config/openbox/lubuntu-rc.xml ~/.config/openbox/lubuntu-rc.xml.backup

Open an editor and modify the configuration file:

leafpad ~/.config/openbox/lubuntu-rc.xml

Search for the following section:

<!-- Launch scrot when Print is pressed -->
<keybind key="Print">
  <action name="Execute">
    <command>...</command>
  </action>
</keybind>

Replace the stuff between the command tags with the following:
More detailed with the file naming format: http://www.linuxmanpages.com/man3/strftime.3.php

scrot '%Y-%m-%d-%H-%M-%S_$wx$h.jpeg'

Save and close lubuntu-rc.xml.

Update Openbox:

openbox --reconfigure

 

Restoring previous settings

Revert settings from previous backup:

cp ~/.config/openbox/lubuntu-rc.xml.backup ~/.config/openbox/lubuntu-rc.xml
