Better Compton Compositing (better than other choices too)

I came from Lubuntu using Compton. However, I noticed that Compton in Mate is not the Compton I was used to using. This tip will say how to get Transparent Windows and menus and fading which are standard for Compton.

  1. Install Compton-conf
    sudo apt install compton-conf

  2. Select "Marco (No Compositor)" in the Mate Tweak applet.

  3. Add compton to your "startup applications"

For some reason, the standard way to have compton added (by checkbox in Tweak), does not work.

Reboot or re-login. You should see the menu bar difference.
You can play with the settings which will appear in the "control center" as "Windows Effects"

Some settings you opt to change may lag the system but should be great according to the default settings. Opacity and fading is easily adjusted to your liking.

I still believe backporting Compiz is better, but that’s just because I like a siper-fancy 3D desktop. If Compton is all you need, then that’s fine; different strokes n’ all.

Yes… Compton is very low weight. I have a low weight computer. It is pretty amazing for the memory it uses.

I have only played around with compton. I look forward to seeing you add more to your compton tutorial.

This is what i do:

Go to mate tweak and select select the “windows” tab and then select “marco (no compositor)”.

Then go to “system/personal/startup applications” and add Compton as a startup application.

Then open a blank Pluma file and paste the following into it:

Save the Pluma file as “compton.conf” in your “.config” folder in your home folders (your “.config” folder is hidden and so you need to press CTRL/h to make it visible).

Then log out and back in. You should find you have panel and window shadows and various menu and window decoration transparencies.

If you want to change any of the values of the transparency and shadow effect, you will need to edit the “compton.conf” file.

Why don’t you use Marco (Compton) in MATE Tweak?

Hi Martin.

Because it does not, out of the box, provide the transparencies or shadows I get with my own Compton configuration. If I use the Marco-Compton configuration in Mate Tweak, it does not read my compton.conf for some reason (or, at least, it didn’t last time I tried it). By loading Compton separately, it does. I’ve no idea why.

Here’s what I get with my own configuration:

Thanks ! i will check it up after work !! :blush:

The default compton configuration that comes with Mate Tweak gives more fancy effects like shadow and fading, but personally I like more static, simple and fast windows management, this is what I get by using a modified version of compton.conf file :

compton.conf :

backend = "glx";
glx-no-stencil = true;
glx-copy-from-front = false;
glx-use-copysubbuffermesa = true;
glx-no-rebind-pixmap = true;
glx-swap-method = 3;
paint-on-overlay = true;
vsync = "opengl-swc"; 

# Shadow
shadow = false;
shadow-ignore-shaped = true;
no-dock-shadow = true;
no-dnd-shadow = true;
clear-shadow = true;

# Fading
fading = false;
no-fading-openclose = true;

# Window type settings
wintypes:
{
	tooltip =
    {
        fade = false;
        shadow = false;
    };
};


vsync = "opengl-swc";
dbe = true;
paint-on-overlay = true;
sw-opti = false;
unredir-if-possible = true;

When I use Marco (software compositor) I get screen tear, when I change to Compiz (Advanced GPU accelerated desktop effects) I get no screen tear.

Compton gives also good results and avoid most screen tearing. But as you, compiz is for now the best against screen tear

@Med_Medin, thank you for your configuration!

I would like to use this one to completely disable shadows.

Where do I put this configuration for MATE to use it?

  • /etc/xdg/compton.conf
  • ~/.config/compton.conf
  • ~/.compton.conf

The “compton.conf” file should be placed in the “username/.config” folder

@orschiro

  • The compton.conf file should be placed in ~/.config folder,
  • and you should choose “Marco(No compositor)” as window manager in Mate Tweak,
  • then finally add an entry to start up programs with the following command “compton -b”

Thank you, @Med_Medin!

Or you can actually use shadows = false; inside ~/config/marco-compton.conf. :slight_smile:
