Today I turn on my computer, Mint I want to turn on my second monitor in the settings but system settings are not showing up.
-> I click the menu icon, I type system then click system settings that just showed up in the bar, then nothing happens
I tried what is suggested here : https://askubuntu.com/questions/575548/system-settings-stopped-showing-up
sudo apt-get install unity-control-center
sudo apt-get install --reinstall ubuntu-desktop
This didn't do anything.
I guess a solution would be to uninstall system settings and reinstall it but I have no idea which package it can be.
