Screensaver is not disabled during install

[Will Cooke]

I was running the screenreader desktop ISO tests and while the install was progressing the screen blanked and locked.

This meant that when the install was complete the screenreader didnt tell me and so I had no way of knowing what was going on.

Speaking to Laney about this, the code which previously disabled the screensaver needed updating to work with different gsettings keys.

thanks, once the disco merge request is reviewed and in, we can look at backporting

ubiquity (19.04.6) disco; urgency=medium

  * Automatic update of included source packages: user-setup
    1.63ubuntu6.
  * gtk: Disable screen blanking for Shell.
    With the switch to GNOME Shell, we're no longer using GNOME Screensaver
    to handle blanking the screen. Setting the `idle-delay' to 0 disables
    this for Shell.
  * gtk, kde: Don't allow going back once we are anywhere past partitioning.
    The effect of this is that proceeding backwards from usersetup to
    timezone is not permitted any more. This is a harmful thing to be able
    to do because the timezone step 'resets' debconf after it finishes, and
    this might break an ongoing installation.
