Gnome Dark Mode

[padorange]

Liferea 1.14.4
Debian 12 stable (bookworm)
Gnome 43.6

The FAQ tell dark-mode is automatically selected since 1.14
There should be a problem, with my configuration liferea is not un dark mode and it make difficult to read. ie the number of unread article is invisible.

Works for me using 1.14.4 and GNOME 44.0 (Ubuntu 23.04). I also know it works for a lot of other users. Not sure what is happening in your case though.

Can you run Liferea with --debug-html and provide the output that happens when you switch to/from dark mode?

[padorange]

i run in debug from console but it produce no output (don't know where is the output file, if any).
But when i switch "live" (before running liferea or after launch liferea) if do nothing in liferea (no change, no output). All other software switch)

[padorange]

I post too quickly.
Runnng liferea from console as admin (sudo) i got an output to the console.
Running in darkmode show that liferea detect "light mode" :

HTML   : theme color "GTK-COLOR-BG" is F6F5F4
HTML   : theme color "GTK-COLOR-LIGHT" is FFFFFF

@padorange Thanks for posting this trace. Can you do an additional run with --debug-html --debug-conf this should give some more output whether the FreeDesktop.org, GNOME settings or defaulting does happen in your case.

A strange thing in you debug output is

 HTML   : theme color "GTK-COLOR-FG" is FFFFFF
 HTML   : theme color "GTK-COLOR-BG" is F6F5F4

This background against this foreground color sounds weird...

@lwindolf
GTK-COLOR-FG and BG are weird, there must be very light, but as you can see on my initial message the color seems "normal" for a light mode (except is was in "dark mode").

This new trace give a bit more information.
But when i do "sudo liferea" it launch another "config", i do not have my feeds (just examples) and the color are not exactly the same (the counter for unread messages is more visible but still light-mode) : see a new screenshot...

@padorange I see, by using sudo you are running liferea as root and with the root GTK/GNOME profile, which does not match your actual user profile. For actual debugging you would need to run liferea from a terminal, but without sudo.

[padorange]

@lwindolf if i do not use sudo the debugs options output nothing in the terminal.
I do not know where the output is located (if any)

[lwindolf]

@padorange Debug output only goes to the terminal (to STDOUT), nowhere else. So what you did was fine.

Now the problem seems to be why Liferea does not see the theme switch at all. Technically it listens to the GNOME DConf key for the color schema, but the callback (according to your trace is just never triggered). So color does not change.

Sadly I cannot reproduce this.

Thanks to have taken time on this.
Perhaps there is a right privilege problem...
