[Bug 1971097] Re: Cannot switch between light/dark theme in the GNOME session

2022-05-12 Thread Jeremy Bicha
Sorry, this is a WONTFIX for Ubuntu 22.04 LTS. Ubuntu 22.04 LTS uses
gnome-control-center 41 which doesn't support setting a theme at all,
except in an Ubuntu-specific patch. If you want the Ubuntu experience,
use the Ubuntu session. If you want the GNOME experience, use the GNOME
session but then you won't get Ubuntu-specific behavior.

This will be fixed in Ubuntu 22.10 which will include gnome-control-
center 42 (or probably 43 actually).

I think the best path forward here is for GNOME Tweaks to set the dark
color theme preference when setting a dark theme, probably
automatically. If that is done, we can backport that bugfix to Ubuntu
22.04 LTS.

apport information

** Tags added: apport-collected jammy wayland-session

** Description changed:

  In the Ubuntu session, gnome-control-center has an "Appearance" section
  which allows to switch from Light and Dark themes (which will apply to
  GTK4 apps as well as set the preference for GTK3 apps), but that section
  doesn't exist in the control center in the GNOME session.
  
  This means that while you can still choose alternate themes using GNOME
  Tweaks, they won't properly apply the chosen variant, and by default
  setting a dark theme will apply that theme's light variant to GTK3 apps
  while also not switching GTK4 apps to the dark variant of libadwaita.
  
  You can set the which variant with the command line ("gsettings set
  org.gnome.desktop.interface color-scheme prefer-dark"), but you cannot
  do this within the UI from the GNOME session like you can from the
  Ubuntu session.
  
- My understanding is that this stems from the gnome-control-center being
- in its 41.4 version, with the light/dark switch backported in for the
- Ubuntu session but not the GNOME session.  That in my opinion doesn't
- make for a great user experience in the GNOME session.
