Hi and welcome.

I would strongly advise that you do not 'bump' threads, I am not a moderator but if it continues you could face a temporary or permanent ban.

This is what I found using Ubuntu 24.04 in my search criteria as Zorin 18 is a fork of Ubuntu 24.04:

" Picom is a lightweight X11 compositor that can replace the default compositor in Ubuntu 24.04 on a Raspberry Pi, but only if you are using an X11 session —not Wayland.

:white_check_mark: Prerequisites

  • You must be running X11 (not Wayland) on your Raspberry Pi. Check with:
echo $XDG_SESSION_TYPE

If it returns wayland , you cannot use picom as it only works with X11.

:wrench: Installation

Install picom using the package manager:

sudo apt update && sudo apt install picom

Note: picom is available in Ubuntu 24.04's default repositories, so no compilation is needed.

:file_folder: Configuration

Create the config directory and file:

mkdir -p ~/.config/picom
nano ~/.config/picom/picom.conf

Add a basic configuration (example):

# Basic Picom Config
opacity-rule = [ "85:class_g *?= 'gnome-terminal'" ];
fading = true;
shadow = true;
shadow-radius = 5;
shadow-offset-x = -5;
shadow-offset-y = -5;
shadow-opacity = 0.8;

Save and exit (Ctrl+O , Enter , Ctrl+X ).

:counterclockwise_arrows_button: Replace Default Compositor

Ubuntu 24.04 with GNOME uses its own compositor (Mutter), which runs by default. To use picom , you must disable the default compositor and start picom manually.

Add the following to your ~/.xprofile (create it if it doesn’t exist):

# Start picom on X11 login
picom --config ~/.config/picom/picom.conf &

Ensure ~/.xprofile is executable:

chmod +x ~/.xprofile

:rocket: Start or Restart

  • Log out and log back in, or restart your Raspberry Pi.
  • picom will now run automatically on X11 login.

:warning: Important Notes

  • Wayland compatibility : picom does not work on Wayland. If you’re using GNOME on Ubuntu 24.04, it defaults to Wayland. Switch to X11 at login (click the gear icon and select "Ubuntu on Xorg").
  • Window Manager : If you’re using a tiling window manager like i3 , dwm , or awesome , you can start picom directly in your config (e.g., exec_always picom --config ~/.config/picom/picom.conf ).

For best results, use picom with a minimal desktop environment (e.g., Xfce, LXDE, or a tiling WM) on Raspberry Pi to avoid conflicts with GNOME’s compositor.

thanks for the warning about bumping,
after i read your post i realized i was on wayland, i thought it was x11.
anyway i guess im not gonna use picom, do you know any other compositor like picom for wayland?
thanks for the reply

I don't think so. All I could find is this:

If it had been quite a while, I think anyone can forgive redrawing attention to your issue - as it could have been missed being seen.
But yes, after less than a day, that is an impatient bump.

The best way to bump a thread is to post a follow up that contributes.
For example, after you have waited a while and are getting anxious, make a new post where you show your work.
You say you are trying to use Picom, so showing the additional research you did while waiting and asking for clarification on it cannot reasonably be accused of a Bump.

Do you ask because you think you have to use Wayland? (You don't.)
Or because you really want to use Wayland?
