"Unable to contact settings server"

[Einheit-101]

I get the following error in Termux:

dbus-update-activation-environment: error: unable to connect to D-Bus: Failed to connect to socket /data/data/com.termux/files/usr/tmp/dbus-vMLxtn7eRF: Connection refused

No idea.

Found it — this was a real bug in the script, now fixed on main.

Two things were wrong:

1. dbus was never installed. None of the Termux desktop metapackages depend on it — I checked xfce4, xfce4-session, xfce4-settings and xfconf, and none of them pull it in. But every one of them needs a session bus to reach its settings daemon, which is exactly what "Unable to contact settings server" means.

2. start-linux.sh killed the bus without ever starting one. It ran pkill -9 -f dbus-daemon during cleanup and then went straight to launching the desktop. A SIGKILLed daemon also leaves a dead socket in $PREFIX/tmp and a stale address in ~/.dbus, which the desktop then tries to reuse — that is where your Connection refused on /tmp/dbus-vMLxtn7eRF comes from.

The script now installs dbus with the desktop, and start-linux.sh clears the stale state and starts a bus at a fixed address before launching, then calls dbus-update-activation-environment once DISPLAY exists so daemons the bus starts on demand inherit a working environment.

To fix your current install, either re-run termux-linux-setup.sh (it regenerates the launchers), or do it by hand:

pkg install dbus
pkill -9 -f dbus-daemon
rm -rf ~/.dbus "$PREFIX"/tmp/dbus-*
mkdir -p "$PREFIX/var/run/dbus"
export DBUS_SESSION_BUS_ADDRESS="unix:path=$PREFIX/var/run/dbus/session_bus_socket"
dbus-daemon --session --address="$DBUS_SESSION_BUS_ADDRESS" --nopidfile --fork

Then start the desktop as usual. Let me know if it comes up clean.

I don't know if it works now because I managed to install it with the help of some Google AI and i dont want to Touch it anymore now that everything runs fine, but thanks for the fix. It sure helps people in the future.
