Overlay Grid is not disabled when modifying unity-greeter.conf

Asked by Alexandre Patenaude

I'm trying to disable the overlay grid (the dots over the background) at the login screen. I've read that there is a new option for this:

- Open /etc/lightdm/unity-greeter.conf as an administrator
- Change "draw-grid=true" to "draw-grid=false"
- Save the file.

I followed these steps, but when switching to another user at the login screen, the grid still shows. I tried stopping and re-running lightdm service ("sudo service lightdm stop && sudo service lightdm start"), thinking the unity-greeter.conf has the be re-read for the new setting to be applied, but no difference. A system reboot neither: the login screen stil show the overlay grid.

I also found there is a GSettings key, "com.canonical.unity-greeter draw-grid", which defaults to "true". I'm not sure what it is supposed to do, as the GSetting base can be edited as a non-admin user. Does this setting affects all users? or only one user? (I.e. if I set this key to "false", will it affect only my backgroud at the login screen [my background won't have the grid over it, but all other users would have it]?)

The settings were moved to gsettings as this was easier for packages to override them. The easiest way to set the defaults is to make an override file in /usr/share/glib-2.0/schemas/, e.g. unity-greeter.override:

[com.canonical.unity-greeter]
draw-grid=false

Then run:
sudo glib-compile-schemas /usr/share/glib-2.0/schemas/

Thank you for answering me and validating it's not a bug. I will try your solution as soon as possible!

But are you planning to implement an easier way of tweaking unity-greeter? A way a user could enable or disable by himself the overlay grid for his own username at the login screen? Though I agree generally only admins will enable/disable this feature and certainly won't change the setting very often...
