[unity-greeter]: background image not changed when upgrading
After upgrading Trisquel Mini 10.0.1 LTS "Nabia" to Trisquel Mini 11.0 LTS "Aramo" using 'Software Updater', the unity-greeter maintains the "Nabia" background image. Changing it involves running the command "xhost SI:localuser:lightdm && sudo -u lightdm dconf-editor", navigate to com/canonical/unity-greeter, click ‘background’, disable use default value, and input custom file PATH to specify the new "Aramo" background image. This is not straight forward and hopefully it maybe possible to automate this process during upgrading?
