On Arch-based distributions, Deepin system apps don't respect their own colorscheme.

[gardotd426]

Describe the bug

When you select "Dark" for the theme in the Control Center, all Deepin apps (Control Center, Boot Maker, Music, Movie, etc.) refuse to actually use a dark color scheme. I have seen first-hand that this is DOES work in the actual Deepin V20 Beta, but outside of Deepin, on Arch and Manjaro, it doesn't work. Everything in Deepin is stuck on a light colorscheme, no matter what you do. The system theme IS reported as "dark/deepin," but it doesn't work, except for non-Deepin apps. I suspect this has a common cause to the icons not working in the control center, which I have also seen DO work in the Beta, but not in Arch/Manjaro.

To Reproduce

1. Be running the latest Deepin DE packages on an Arch-based Linux system.
2. Open Control Center
3. Select "Personalization," then "Dark" under the "Theme" section.
4. See error. Reboot or log out if you like, the error will persist. Other, non-Deepin apps will appear with the dark topbar, but all Deepin applications remain bleach-white.

Expected behavior

For the theming to actually work in any way whatsoever. Like this:

But instead, you get this:

Hell, you can even see in this photo that the "Dark" theme is supposedly active in the Control Center though it's very obviously not:

Additional context

Again, it very obviously works on the Deepin Beta (at least for some people), but it very clearly is not working here. No idea why, I've looked everywhere. I tried deepin-mutter even though it's deprecated after Deepin-Kwin wouldn't work no matter what. I removed all QT environment variables, installed qt5ct, uninstalled qt5ct, nothing works.

[es20490446e]

Everything is completely broken:

[Y0ngg4n]

Same behavior here on Manjaro, missing Icons everywhere and the Dark Mode does not apply if you select it. Also the Transparency Slider is non existent. Missing Icons everywhere aswell as in the login screen. If you tell me, where i can find some usefull logs i can paste them here.

[polluxmaster]

Same here, everything is broken after last update

[felixonmars]

I cannot reproduce any of these on my Arch system though. Can you try to replace deepin-desktop-schemas-manjaro with Arch's deepin-desktop-schemas and see if anything changes?

[es20490446e]

When I have a moment I will test.

Discussion on Manjaro here.

[es20490446e]

Dalto confirms it's the same on Arch, so deepin-desktop-schemas-manjaro isn't the cause.

[Y0ngg4n]

After uninstallation of deepin-desktop-schemas-manjaro i had some problems with plymout-theme-manjaro-deepin and my system won´t boot. After some tries to fix it i just restored a backup with Deepin 15 so i can get my work done until they fix this issues.

[felixonmars]

@es20490446e Figured it out. Please try deepin-qt5integration 5.1.0.1-2.

For more info: https://github.com/linuxdeepin/qt5integration/pull/26

[dalto8]

deepin-qt5integration 5.1.0.1-2 fixes it for me.

Thanks!

[Hsins]

The icons are shown after I update to deepin-qt5integration 5.1.01-2 on my Manjaro system. But there are problems with the login screen (missing icons).

[felixonmars]

The login screen works correctly here. Do you have same issues with the lock screen etc?

[nalakawula]

+1 instaal deepin in arch based distro, today. And this issue happen to me

[Y0ngg4n]

I can verify that it works on Manjaro with deepin-qt5integration 5.1.0.1-2. The icons are there and the Theme do also apply, but the Search bar in Settings does not work and the Transparency Bar in Appeareance is missing.

[gardotd426]

@Y0ngg4n if you're using the default deepin installation on Manjaro, then you have to instead install deepin-kwin, as sudo pacman -S deepin deepin-extra on Manjaro will install deepin-mutter as the window manager instead, which is deprecated. With deepin-mutter as the WM, you won't get the transparency slider or window effect button, because deepin-mutter was deprecated months ago, and Deepin v20 is a complete overhaul of the DE so obviously it won't work with the deprecated window manager.

Install deepin-kwin and remove deepin-mutter. Actually, you shouldn't need to remove deepin-mutter because it will default to deepin-kwin, but I would uninstall it just in case.

[dalto8]

@felixonmars should the default packaging on Arch be changed to use deepin-kwin instead of deepin-mutter?

[gardotd426]

@dalto8 I would say that's a pretty objectively clear yes, look for yourself: https://github.com/linuxdeepin/deepin-mutter The title of the page is literally "deepin-mutter DEPRECATED," the repo is archived read-only (which by definition should make it removed from the deepin group on Arch as bugs can't even be fixed anymore), and the last commit was 5 years ago.

Meanwhile deepin-kwin is the actual window manager for the Deepin desktop environment.

[felixonmars]

Okay. I think it's enough reason to make it the default for now regardless of the bug. I added deepin-kwin to deepin group in 5.0.14.1-3, which will effectively make it the default in new installations while users are still able to uninstall it if they prefer deepin-wm somehow. Old installations won't be affected.

[gardotd426]

@felixonmars absolutely, I mean sure there are some bugs left in the new Deepin DE but that's to be expected, but at least with deepin-kwin those bugs can be addressed, they'll never be fixed in deepin-mutter. Which is unfortunate, because I preferred deepin-mutter on the old pre-v20 deepin de, but still.

[dalto8]

Thanks @felixonmars, can we also remove dependencies on deepin-mutter?

[felixonmars]

Will do shortly.

[gardotd426]

Are the window titlebars supposed to stay white even when the theme is set to dark? Because that's the behavior I'm getting.

[dalto8]

@gardotd426 which applications? It is working fine here for me with the apps I have tested.

[gardotd426]

@dalto8 Every non-deepin application. Alacritty, chrome, firefox, radeon-profile, kitty, a million of them. Someone else has already filed a bug for it so obviously it's an issue for other people too.

Ignore the hideous black borders, that's yet another bug (like the 6th I've encountered so far), but I've filed a separate issue for that. Note how every window essentially has a white titlebar. Except of course the control center, because that's a deepin app, and I've set the "dark" color scheme.

[Y0ngg4n]

@gardotd426 Same behavior here on Manjaro.

[Y0ngg4n]

@gardotd426 @dalto8 Here an example image of the behavior:

[gardotd426]

@Y0ngg4n try opening the Control Center, clicking on "Light" for the theme, and then clicking on "Dark" again. That's what I had to do.

[Y0ngg4n]

@gardotd426 Thanks for this workaround!

[SiamSami]

One thing that needs to be mentioned is that manjaro by default makes use of qt5ct. You should remove the following line export QT_QPA_PLATFORMTHEME="qt5ct" from ~/.xprofile.

[gardotd426]

I don't have that in my ~/.xprofile, and Manjaro actually doesn't do that by default anyway (it doesn't even install qt5ct unless you tell it to, or you can just remove qt5ct, nothing in Deepin DE requires it).

But either way, it seems it's been fixed, I'm gonna go ahead and close it. Plenty more bugs to track down, but this one's fixed.

[YuriFontella]

This old problem still persists in the current Deepin packages on Arch Linux.

In the control center, even when switching between dark and light, the applications do not receive the theme. It is necessary to manually change the theme option in each application.

In Deepin 23, the dock also has its theme changed. In Deepin with Arch Linux, the dock refuses to receive the dark theme in any way.

There are still problems with animations and shortcut keys that do not work.
