I'm trying to set up a second screen on my laptop. I plugged the screen using the VGA port and go to Preferences -> Display.

The screen is correctly detected, but when I try to activate it, an error is raised:

Failure of the configuration application: %s (translated from the French sentence from the screenshot below)

GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.cinnamon.SettingsDaemon was not provided by any .service files

Screenshot of the error

I don't know if it can help:

~$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 09)

I did not find anything on the Internet about this specific setting... Does anyone know how to fix this? Thanks.

I received this error because cinnamon-settings-daemon was not running. You can check if it is running as the following command will list it:

pgrep -fa cinnamon-settings-daemon

If cinnamon-settings-daemon appears in the output of the above command then your issue is different to mine. Otherwise, run it from the terminal as follows:

cinnamon-settings-daemon &

This should enable you to change the screen settings.

Out of interest, cinnamon-settings-daemon wasn't starting on login because of this issue. Doing the following and then running cinnamon-settings-daemon fixed it for me:

rm -f ~/.config/monitors.xml{,.backup}
  • I totally forgot about this post... I resolved my issue two or three weeks later... by upgrading to Linux Mint last version :-) I will never know if this could resolve my issue, sorry. – Maxime Lorant Nov 24 '15 at 15:18
  • Confirmed this works on a fresh install of Linux Mint 18 – crypdick Dec 5 '16 at 3:37
  • similar issue on Ubuntu 17.10 and additionally the daemon was renamed. i needed to launch /usr/lib/x86_64-linux-gnu/cinnamon-settings-daemon/csd-xrandr in a terminal to make the gui work. – mnagel Feb 28 at 13:24

I resolved the problem by upgrading to the last version of Linux Mint.

I don't know if the answer of @Homme Zwaagstra would solve the issue, so I prefer to accept my own answer.

I had a similar problem to what Homme Zwaagstra described. The difference, however, was that I had accidentally turned off cinnamon-settings-daemon as a startup application. If you are having this problem you could open up your startup applications manager and make sure that cinnamon-settings-daemon is running on startup.
