Inconsistent theme for GTK dialogs

[kgilmer]

Some dialogs appear light, others dark on Ubuntu Jammy (possibly others)

I think I found the solution.  I can set the gnome colour scheme via :
gsettings set org.gnome.desktop.interface color-scheme prefer-dark  or prefer-light

Seems to be something from gnome-flashback: https://gitlab.gnome.org/GNOME/gnome-flashback/-/issues/81

I don't use regolith-desktop but this package, which is part of regolith-desktop, instead.

What I notice is that it isn't just the dialog theme that is inconsistent. It's actually the color theme of all gnome-flashback related GUI. E.g. the notification tray and notification popups, which are shipped with gnome-flashback, are sometimes white.

I couldn't find out what triggers this behavior. Sometimes the gnome-flashback GUI is white on boot, sometimes it's dark. Sometimes it changes to white after a lock or suspend and sometimes not.

I have done the following to change the color schemes:

gsettings set org.gnome.desktop.interface color-scheme 'prefer-dark'
gsettings set org.gnome.desktop.interface gtk-theme 'Yaru-blue-dark'

I think we just need to wait until the upstream bug @kgilmer metioned is fixed.

The fix is available now in jammy-proposed. I have not seen a problem since taking the update.

@kgilmer hm i installed the pre-release update but still see the light dialogs:

❯ apt search regolith-desktop
Sorting... Done
Full Text Search... Done
regolith-desktop/unknown,now 4.2.0-1regolith amd64 [installed]
  metapackage for Regolith desktop environment

[p3k]

just a short update: between logins, the theme erratically switches between the correct dark mode and the incorrect light mode as seen in the screenshot above.

any idea what could be going on @kgilmer? anything i could post to provide more information?

[kgilmer]

What distro/release are you using @p3k . What version of gnome-flashback do you have installed?

[p3k]

oh my bad timing as plenty of times: just shortly after my yesterday’s posting i ran apt upgrade and saw gnome-flashback mentioned in the listing of upgradable packages:

Unpacking gnome-flashback (3.44.0-1ubuntu2) over (3.44.0-1ubuntu1) ...

wanted to check after another reboot / first login and what can i say: indeed, for the first time the logout alert, volume control etc. appeared in dark mode right afterwards.

the version string of gnome-flashback did not change, afair:

❯ gnome-flashback -v
gnome-flashback 3.44.0

# distro / release for the record:
❯ lsb_release -ds; uname -smor
Ubuntu 22.04.1 LTS
Linux 5.15.0-46-generic x86_64 GNU/Linux

anyway, thanks for your feedback, @kgilmer. gonna evaluate some more reboots and if this remans the status quo now, i am going to close this issue.

works for me now and this issue can be closed (which i am not allowed to do).

Hello & sorry for reviving this bug! :sweat: Even with the following commands and the dark theme chosen from gnome settings (+ gnome tweaks checked), and the following commands applied, I can't get Regolith (under Ubuntu 24.04) to use the dark scheme, it seems overriden by the theme or something..

Here is some additional context:

regolith-diagnostic | grep -iP 'ligh|version|dark'
--- /etc/regolith/version:
REGOLITH_VERSION=3.2
Xft.hintstyle:  hintslight

org.gnome.settings-daemon.plugins.media-keys keyboard-brightness-toggle-static ['XF86KbdLightOnOff']

I'm not sure whether the issue lies in Ubuntu 24.04 (which was/is a pain to adopt), or from a theme applied, or the color palette overriding stuff... For more context: All the code to reproduce the issue can be found in the offensive regolith & mise-en-place based distro I maintain: https://github.com/laluka/lalubuntu :rose:

Cheers!
