feat: replaces gnome dependencies with cosmic components #1

[sandptel]

This replaces the following gnome dependencies with the following cosmic ones.

• regolith-control-center -> cosmic-settings + cosmic-settings-daemon
• + cosmic-idle
• swaybg -> cosmic-bg
• gtk_lock -> ?
• gnome-session-quit -> systemctl/loginctl
• nautilus -> cosmic-files

The following config can be used with https://github.com/sandptel/regolith-session/tree/cosmic-session inside of the cosmic-sys-ext environment as mentioned below. Or can be tested locally

git clone https://github.com/sandptel/regolith-wm-config
cd regolith-wm-config

Launch the session using the following

cosmic-session sway --config ./etc/regolith/sway/config -d

This configuration work in pair with the following fork of cosmic-settings that convert the cosmic-settings changes to sway-ipc commands via swayipc-rs within the application for hot loading the changes and an equivalent sway config is added/changed at $HOME/.config/regolith3/sway/cosmic-settings/generated-config.d/*

include $HOME/.config/regolith3/sway/cosmic-settings/generated-config.d/*

Testing Environment

sudo apt install just rustc libglvnd-dev libwayland-dev libseat-dev libxkbcommon-dev libinput-dev udev dbus libdbus-1-dev libsystemd-dev libpixman-1-dev libssl-dev libflatpak-dev libpulse-dev pop-launcher libexpat1-dev libfontconfig-dev libfreetype-dev mold cargo libgbm-dev libclang-dev libpipewire-0.3-dev libpam0g-dev -y

and some extra dependencies I found were missing in the list when compiling cosmic-applets

sudo apt install libdisplay-info-dev
sudo apt install gstreamer-sys
sudo apt install libgstreamer1.0-dev gstreamer1.0-plugins-base gstreamer1.0-plugins-good
sudo apt install libgstreamer-plugins-base1.0-dev

git clone --recurse-submodules https://github.com/pop-os/cosmic-epoch
cd cosmic-epoch
just sysext

gnome-flashback-media-keys is for X11. Anything that has flashback mentioned on it deals with the i3 session. COSMIC is wayland only hence a COSMIC session would be sway only

What degree of success have you had with running this session with cosmic-sysext? Also are the dependency names placeholders, since I'm not sure if the packages for COSMIC's Debian / Ubuntu sessions are available.

What degree of success have you had with running this session with cosmic-sysext? Also are the dependency names placeholders, since I'm not sure if the packages for COSMIC's Debian / Ubuntu sessions are available.

So the dependency names are placeholders but We can use the OpenSUSE Build Service that provides COSMIC Packages for Debian.

echo 'deb http://download.opensuse.org/repositories/home:/nomispaz:/debian:/cosmic-desktop/Debian_Testing/ /' | sudo tee /etc/apt/sources.list.d/home:nomispaz:debian:cosmic-desktop.list
curl -fsSL https://download.opensuse.org/repositories/home:nomispaz:debian:cosmic-desktop/Debian_Testing/Release.key | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/home_nomispaz_debian_cosmic-desktop.gpg > /dev/null

sudo apt update

I have tried removing the sysext and used these applications on Debian and it works the same as sysext.
