 Posted: Wed Feb 08, 2023 4:18 pm Post subject: startplasma-x11 doesn't launch dbus-launch [SOLVED] |
 |
|
Since I usually do multiple logins (using different users) on the same system, I always login a CLI instance.
If I need a GUI interface then I do: | Code: | | XSESSION=startlxqt startx |
or | Code: | | XSESSION=startplasma-x11 startx |
I just built a new system and | Code: | | XSESSION=startplasma-x11 startx |
fails to start 'dbus-launch' resulting in a black screen and the following message from Xorg.0.log: | Code: | (EE) dbus-core: error connecting to system bus: org.freedesktop.DBus.Error.FileNotFound
(Failed to connect to socket /run/dbus/system_bus_socket: No such file or directory) |
On the other hand, | Code: | | XSESSION=startlxqt startx |
works as expected. Inspection of /usr/bin/startlxqt reveals that it is a bash script and starts dbus-launch (if needed) | Code: | # Launch DBus if needed
if [ -z "$DBUS_SESSION_BUS_ADDRESS" ]; then
if [ -z "$XDG_RUNTIME_DIR" ] || ! [ -S "$XDG_RUNTIME_DIR/bus" ] || ! [ -O "$XDG_RUNTIME_DIR/bus" ]; then
eval "$(dbus-launch --sh-syntax --exit-with-session)" || echo "startlxqt: error executing dbus-launch" >&2
fi
fi |
resulting in | Code: | | root 2701 0.0 0.0 4400 2152 tty1 S 09:54 0:00 /usr/bin/dbus-launch --exit-with-session /usr/bin/startlxqt |
In theory, I should be able to insert this code fragment into /usr/bin/startx or perhaps some related script such as xinitrc. However, I am not a DEV GOD or similar and have no confidence about doing so.
Two questions:- Is this a bug and should I report is as such? With plasma perhaps?
- Could someone give guidance on how to add the start of dbus-launch to /usr/bin/startx? i.e. I don't know where the various environmental variables come from and whether they are populated at the execution of startx, etc.
I really am not interested in booting my computers in an initial GUI and that goes double for my headless computers. I make extensive use of X2go so I'd rather everything initially boot in CLI mode.

Seems to be looking for system dbus, not user session's dbus. Aka what openrc/systemd would start at boot (/run/dbus/system_bus_socket is typically owned by root, users can't create this), check if enabled? With e.g. openrc, when using display-manager-init (for sddm, xdm and friends), it would normally get auto-started but you need to explicitly enable it if using startx.
Not everything needs this, so lxqt may just happen to be fine without it. |

I missed the difference between system and user. However 'ls' reports: | Code: | # ls -l /run/dbus
total 0
srwxrwxrwx 1 root root 0 Feb 8 09:53 system_bus_socket |
so the file exists and, if I'm reading the permissions correctly, everyone should be able to access it. I guess I'm missing something else.

Closing this because I completely misunderstood the true nature of the problem/made progress and now consider this thread to be a potential red herring. 'dbus-launch' now starts properly for both users and root.
The new problem is that 'startplasma-x11' always ends up with a non-responsive black screen. I've tracked this down to 'kde-plasma/plasma-meta' not being part of the initial install.
