I received this critical error in my logs, but I haven't had any problems so far. If anyone knows why I get this error and what it means, I'd really appreciate an answer from you.
CRITICAL: Unable to create a DBus proxy for GnomeScreensaver: Error calling StartServiceByName for org.gnome.ScreenSaver: GDBus.Error:org.freedesktop.DBus.Error.Spawn.ChildExited: Process org.gnome.ScreenSaver exited with status 1
I have a problem when I try to connect my guitar to my computer, via line input. Audacity works well, and I can record what I play on my guitar (selecting from Preferences from where to record to default:line0). But the problem is in Qjackctl :
at first when I click on start it shows this error:
after that when I click on Cancel it gives this error:

Now I can't understand what my problem is.
I connected an external screen to my laptop, but my desktop didn't automagically extend to it, as it used to do about a year ago (older version of Ubuntu).
I went to the display settings. The screen was listed there (correct resolution, brand name, etc.). But when i put the switch on 'on' and click 'apply', i get this error:
Failed to apply configuration: %s GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: No such interface `org.gnome.SettingsDaemon.XRANDR_2' on object at path /org/gnome/SettingsDaemon/XRANDR
It's been like this for a few months now, but i'd really like to be able to use an external screen/beamer again.
Any ideas?
Thanks.
After installing Konquerer and restarting my laptop i got the following error while trying to open, edit or access files as root from within Terminal (which is existencial for me).
root@linuxBox:/home/v2r#
gnome-open /home/(gnome-open:2686): GConf-WARNING **: Client failed to connect to the D-BUS daemon: //bin/dbus-launch terminated abnormally with the following error: No protocol specified Autolaunch error: X11 initialization failed.
GConf Error: No D-BUS daemon running
root@linuxBox:/home/v2r# No protocol specified Could not parse arguments: Cannot open display:
Also it seems, that dbus is not installed properly anymore in /bin/ and /usr/bin/
See screenshot:
How would i go about fixing this problem and thank you in advance?!!!
Thank you for your answer SirCharlo! It does not resolve the problem at all. Please note, that it only happens while beeing root!

Is there a graphical tool or maybe a command-line one that lists all the messages and parameters/arguments that I can send to a DBUS-enabled program?? I really want to try scripting some DBUS things but I can hardly find any documentation for the DBUS capabilities of most applications.
