Description Roger Sewell 2020-03-21 15:24:33 UTC
Document URL: https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html-single/using_the_desktop_environment_in_rhel_8/index#customizing-desktop-appearance_using-the-desktop-environment-in-rhel-8

Section Number and Name: 5 Customizing desktop appearance

Describe the issue: I cannot find how to make the top bar in GNOME *standard* have any colour other than white text on black background (which for me is nearly invisible, such that I have reverted to GNOME *classic* as the only way to get it to be black on grey).

(I can change the colour of the top bars of all the individual windows without difficulty, just not the colour of the overall screen top bar.)

Suggestions for improvement: Make it clear how to do this - if there is a way. If there isn't any way, then there needs to be.

I just received an email saying 

--- Comment #8 from sagar <sdubewar@redhat.com> ---
Hello Roger,

As per the response from SME, there are three options. Please take a look at
the comment by Florian Müllner and see if the issue resolves by any of the
suggestion provided by him.

Thank you :)

BUT the only comment I can see is this one, despite the above being labelled "comment #8", and pile of "needinfo" flags being set and cleared.

I have tried clicking "expand all comments", which made no difference.

Please could you tell me how to view the comments that currently appear to be hidden from me ?

Thanks !

I'm afraid that despite trying everything I can think of, I can see comment 9 and the original description, but nothing of what has transpired in between other than the following, which is a cut and paste with nothing deleted:

then comment 9, then

So, much as I would like to try the 3 suggestions that Florian and others have made, I cannot see them so do not know what they are.

I have tried pressing "Expand all comments", which makes no difference.

I have also tried looking at bugzilla from a totally different machine, which also makes no difference.

I have tried without being logged in as me, which makes the flag changes invisible, but does not make comments 1-8 visible.

I suspect that in some way the traffic between you, Marek, and Florian is hidden from me as a non-redhatter - but I do not know how.

What happens if you view this bug as an outsider without being logged in ? Can you then see the 3 suggestions that have been made ?

Sorry not to be able to provide the feedback needed, but I just can't see what it is that you are suggesting.

Best wishes,

Comment 15 Sagar Dubewar 2020-04-08 13:28:08 UTC
At this point, there is no direct option to change the appearance of the top bar. It requires loading alternative CSS into the gnome-shell, either via a dedicated extension or via a complete theme and the user-themes extension.

We support the user-themes extension itself. As CSS styles control more than the foreground/background color of elements, they can potentially break shell components in similar ways as 3rd party extensions (which we don't support).

However, the following are the three workarounds:

 1. We may need to develop a "reverse high contrast" theme upstream and support it officially. It is probably the cleanest solution, but it is not a short-term option.

 2. We can make the "classic" style usable with the user-themes extension. The "classic" is a complete and tested style, and making it available to the extension does not require a lot of development.

 3. You can refer to the KBase and use a custom session mode to change the stylesheet. This option has the advantage that it already works, but it's very
    cumbersome to set up. It's roughly the same process as outlined here: https://access.redhat.com/solutions/4243461, except for the first and last steps, and the session mode definition
    the JSON file) would look like this:
      "parentMode": "user",
      "stylesheetName": "gnome-classic.css"
