[Bug 2037676] Re: ubiquity needs to preserve GTK_THEME when launched from live session

[Erich Eickmeyer]

** Changed in: ubuntustudio-default-settings (Ubuntu)
       Status: In Progress => Fix Committed

** Description changed:

  Currently, in Ubuntu Studio, when launched from the live session,
  Ubiquity is using the Adwaita GTK theme, which is inconsistent with the
  experience. The only way I can think of is to modify the
- ubiquity.desktop file's Exec: line to the following:
+ ubiquity.desktop file's Exec= line to the following:
  
- Exec:sudo --preserve-
+ Exec=sudo --preserve-
  env=DBUS_SESSION_BUS_ADDRESS,XDG_DATA_DIRS,XDG_RUNTIME_DIR,GTK_THEME sh
  -c 'ubiquity gtk_ui'
  
  Note the addition of GTK_THEME. This way the GTK theme is specified and
  gets preserved in the sudo environment, so long as it is set.
  
  The other part of this fix is using ubuntustudio-live-settings to set
  the GTK_THEME=Materia-dark variable. As far as I know, this will be the
  only flavor that needs it.
  
  In my testing, no other flavor of Ubuntu required this variable to be
  set as the correct GTK theme seemed to propogate correctly, probably due
  to the desktop environments already being GTK-based.
