lightdm@hemura-X450CC:/home/hemura$ sudo gsettings set com.canonical.unity-greeter draw-grid false [sudo] password for lightdm: Sorry, try again.
i typed the right password but it doesn't work
Why are you even in a shell as the
lightdm user? I'd suggest you log out (Control+D) and log in as your own user. If that's in the
sudo group, you'll be able to use your own password to run whatever it is you're trying to run as root.
It seems that you want to remove the Unity Greeter dots. Use the following commands, in that order:
sudo xhost +SI:localuser:lightdm sudo su lightdm -s /bin/bash gsettings set com.canonical.unity-greeter draw-grid false exit
The problem you made was that you prefixed the
gsettings command with
sudo, which it doesn't need.
