When running the Display settings (gnome-control-center display) under Gnome 3.6 on Ubuntu 13.04 I'm unable to apply any settings (even if nothing changes). The error I get is:  Failed to apply configuration: %s GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.gnome.SettingsDaemon was not provided by any .service files.  Background:  I've tried to use the newer 3.8 release from the PPA's but that didn't help, I've now reverted to the 3.6 release. I've also tried removing all my gnome related config files, but that didn't make a difference.  The error message:

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.

is a neat little program allowing you to adjust color temperature of the screen during the day and separately during the night. Is it possible to achieve this with GNOME 3 on Ubuntu 17.10?   Under Setting → Devices → Displays GNOME allows to enable Night Light which makes the screen somewhat warmer at night. However, it does not allow to adjust the color temperature, and it doesn't work during the day.   How to replicate the Redshift functionality in Gnome 3 on Wayland?

I'm using Ubuntu 13.04 (Raring)  I've installed CompizConfig Settings Manager (CCSM) and wanted to enable the wobbling window effect. This disabled some other things and suddenly I didn't have window borders any more... Following various instructions I found at Google, I've tried the following steps:   Go to CCSM Preferences / Reset to defaults   This disabled all plugins and effects (including Unity) so I didn't get any further...   executing dconf reset -f /org/compiz and rebooting   This brought borders back, but still don't have close/mini/maxi buttons, can't resize or move windows. And the top left entries of the menu bar vanished (Logout, battery, volume...) so I have to shutdown my computer via a terminal...  Edit:   Following the instructions from the first answer.   This brought my menu bar applets back... dpkg-reconfigure didn't seem to work. Result of this command:  /var/lib/dpkg/info/compiz.config: 1: /var/lib/dpkg/info/compiz.config: [general]: not found /var/lib/dpkg/info/compiz.config: 2: /var/lib/dpkg/info/compiz.config: backend: not found /var/lib/dpkg/info/compiz.config: 3: /var/lib/dpkg/info/compiz.config: plugin_list_autosort: not found /var/lib/dpkg/info/compiz.config: 5: /var/lib/dpkg/info/compiz.config: [gnome_session]: not found /var/lib/dpkg/info/compiz.config: 6: /var/lib/dpkg/info/compiz.config: backend: not found /var/lib/dpkg/info/compiz.config: 7: /var/lib/dpkg/info/compiz.config: integration: not found /var/lib/dpkg/info/compiz.config: 8: /var/lib/dpkg/info/compiz.config: plugin_list_autosort: not found /var/lib/dpkg/info/compiz.config: 9: /var/lib/dpkg/info/compiz.config: profile: not found /var/lib/dpkg/info/compiz.config: 11: /var/lib/dpkg/info/compiz.config: [general_ubuntu]: not found /var/lib/dpkg/info/compiz.config: 12: /var/lib/dpkg/info/compiz.config: backend: not found /var/lib/dpkg/info/compiz.config: 13: /var/lib/dpkg/info/compiz.config: integration: not found /var/lib/dpkg/info/compiz.config: 14: /var/lib/dpkg/info/compiz.config: plugin_list_autosort: not found /var/lib/dpkg/info/compiz.config: 15: /var/lib/dpkg/info/compiz.config: profile: not found   Is there any possibility to reset the settings like they were after installing Ubuntu?  Edit 2:  Just noticed that the title bar of windows isn't missing; It's just hidden under the menu bar. So the buttons are only hidden, too.  Edit 3: PROBLEM SOLVED  Started CCSM, went to window management and checked scale windows and move windows... After a re-login everything was fine.

I tried to use the command gnome-control center -l and it gave me an errors saying some shared objects are missing . This is the result :   gnome-control-center -l  libwayland-egl.so.1: cannot open shared object file: No such file or directory Failed to load module: /usr/lib/i386-linux-gnu/unity-control-center-1/panels/libuser-accounts.so Unknown option -l   Run /usr/bin/unity-control-center --help to see a full list of available command line options.  So I tried this and it also gave the same result :  unity-control-center -l  libwayland-egl.so.1: cannot open shared object file: No such file or directory Failed to load module: /usr/lib/i386-linux-gnu/unity-control-center-1/panels/libuser-accounts.so Unknown option -l   Run unity-control-center --help to see a full list of available command line options.

So I tried installing it but it installed some packages meant for ubuntu mobile . I removed those wrong packages and reinstalled the previous ones following  thread and after that everything is good like before but the error I mentioned before about libwayland-egl.so didn't get solved . And still user-accounts.so shows failed to load .   How do I solve this ? I am trying to solve it because I can't access user-accounts from system settings . Whenever I try to access user accounts it always keep showing system settings over and over again . I can't even close it in anyway possible . It just keeps showing up .

UPDATE  I would like to know which is the recommend way of running GUI applications as root, mainly because what I'm trying isn't running smoothly. I get some annoying warnings that makes me think whether I'm doing something wrong or not. I'm using gksudo and sudo -i, which I understand, are doing the same thing. Please let me know if there is some slight differences between them. Regarding the problems I'm experiencing, I would like to start with nautilus (run as root). I can't edit the preferences file maybe because the program couldn't create its own configuration files. A warning says that the folder /root/.config/nautilus must be created. When you start an application for the first time, the program is responsible for creating the configuration files it will potentially need. So, when you are running as root, it should happen the same, shouldn't it? Furthermore, in the shell appears some strange warnings while running this application, such as the followings:  (nautilus:3406): Gtk-WARNING **: Failed to register client: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.gnome.SessionManager was not provided by any .service files Nautilus-Share-Message: Called &quot;net usershare info&quot; but it failed: The &quot;shared network&quot; returned error 255: net usershare: cannot open usershare directory /var/lib/samba/usershares. Error It doesn't exist the file or the folder Please ask your system administrator to enable user sharing.  Other applications like gedit or firefox complained in this way:  (gedit:3444): Gtk-WARNING **: Calling Inhibit failed: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.gnome.SessionManager was not provided by any .service files (gedit:3444): GLib-GIO-WARNING **: Failed to parse translated string ''Monospace 12'' for key 'editor-font' in schema 'org.gnome.gedit.preferences.editor': 0:expected value (gedit:3444): GLib-GIO-WARNING **: Using untranslated default instead. (firefox:2719): Gtk-CRITICAL **: IA__gtk_clipboard_set_with_data: assertion 'targets != NULL  I want to make a clean install of the system soon, but before that, I would like to understand how it works in case I need this stuff in the future for specific things. Though I know it's safer to use the straight sudo in the command line instead. Why this is happening? Thanks in advance

is it possible to set different blank screen timeouts in Ubuntu 18.04 with Gnome when on battery or ac? The power settings menu provides only one field which is applied always, no matter of the current mode.  This question was already asked for the Unity desktop a while ago () and they did not find a solution but I had the hope that that might have changed with Gnome now.

/desktop/gnome/peripherals/keyboard/general/disable_indicator in gconf is set to yes Additionally I restarted, but it's still there. Maybe there is some setting buried in CCSM?  here is screenshot of what I'm talking about if it's not clear:  I want to remove it if possible

I've just upgraded to Ubuntu 17.10 and am missing the Ubuntu Dock settings, i.e. in gnome-control-center the dock settings are blank:    I think I might be missing the "ubuntu-dock" package, but can't find this anywhere in the software centre.  Also the gnome-control-center was completely missing after the update, and I had to install this separately - not sure if this is related.  I think this is different from  because changing the type of GNOME session doesn't fix the problem. If I go for GNOME* I get no Dock settings section at all, and if I got for Ubuntu* I get the blank Dock settings section described above.

I just installed Ubuntu 12.04. I switched to Gnome classic from unity as I'm more comfortable with the former. However, I couldn't find where the panel setting are. Usually a drop down menu appears on right-clicking the top and bottom panels. But it doesn't happen now.  I need the panel settings so as to auto hide the panels (as my netbook screen is quite small!) as well as to add the "system monitor" applet to the panel which is really useful.  Where can I find the panel settings?

I updated to 17.10 from 17.04.   I activated the fractional scaling by running the following command.   gsettings set org.gnome.mutter experimental-features "['scale-monitor-framebuffer']"   Then, I changed 125% scale. The scale was changed, but the fonts and icons are so dirty.    The launcher icon and font in Google Chrome and other application except the system setting are dirty.  How can I resolve this problem?  For some reason, font in the system setting is not dirty...

I accidentally removed the default Gnome panel menu on the top right (containing clock, mail, volume and shutdown options). After, I tried to get the menu back by adding some apps but that did not solve the problem. I then stumbled upon a reset via the terminal, however, the menu remains missing and the apps I added are still there.  sudo dconf reset -f /org/gnome/gnome-panel/ killall gnome-panel   and  gconftool-2 --recursive-unset /apps/panel pkill gnome-panel   System: Ubuntu 12.04 with Gnome classic.  Any help is greatly appreciated! Many thanks in advance.
