GTK applications (including Firefox) are slow to start with GNOME 44

[intgr]

If you also experience this bug, please add a 👍 reaction.

With some recent-ish updates, GTK applications are quite slow to start up, waiting for 25+ seconds before opening any Windows appear.

Sorry, I haven't had time to finish investigating this. But it looks related to xdg-desktop-portal changes in GNOME version 44.

One hack fix for this is commenting out the Requisite=graphical-session.target line in the xdg-desktop-portal-gnome.service unit.

But there has to be a better way to fix this...

For example, run as the ego target user:

mkdir -p ~/.config/systemd/user
cat > ~/.config/systemd/user/xdg-desktop-portal-gnome.service <<EOF
[Unit]
Description=Portal service (GNOME implementation)
After=graphical-session.target
# Requisite=graphical-session.target
PartOf=graphical-session.target

[Service]
Type=dbus
BusName=org.freedesktop.impl.portal.desktop.gnome
ExecStart=/usr/lib/xdg-desktop-portal-gnome
EOF
systemctl --user daemon-reload
