I've installed sparkylinux 4 RC on both desktop and laptop and the icons are awesome.

Previously I used  Mate and I could access laptop brightness keys etc also I was getting visual effects for the keys and now in LXDE the keys are no longer working. What is the app for it?

Install 'xbacklight' package.
Edit the file:
Before :
paste the text:
<keybind key="XF86MonBrightnessDown">
      <action name="Execute">
        <command>xbacklight -20</command>
          <name>Decrease screen brightness</name>
  <keybind key="XF86MonBrightnessUp">
      <action name="Execute">
        <command>xbacklight +20</command>
          <name>Increase screen brightness</name>

Then re-login and use function keys or special + Up/Down keys to change brightness.

Thanks, it's working. But, in previous Mate installations I could see the on-screen display of key effects now I can use the keys but there is no on-screen display.

Anyway it's okay.

Thanks again.

On my laptop I got OSD working (for brightness and volume) applying the following steps:

- installed xfce4-notifyd, stopped autostart of notification deamon unchecking it in Dsktop Session Settings
- installed xfce4-power-manager, added it to autostart checking it in Desktop Session Settings
- installed volumeicon-alsa and created volumeicon.desktop in ~/.config/autostart/:

[Desktop Entry]

After reboot, I had to check control for brightness keys in Power Management and for volume keys in Volumeicon. Now OSD works  :)
