Arch Linux User Repository

Looks like it's over, Plasma 5 is removed from the repos. Now the only things possible to do are to remove the package somehow (how? I don't see such a button) or to wait, maybe someone will re-package the deps in the AUR.

Some user guide:

My patchset contains multiple fixes/features in comparison to vanilla qt5ct:

1. KDE color schemes support
2. KDE QML applications theming support
3. KDE's icon engine is used, fixing monochrome icons colors (I saw problems with e.g. Adapta Kvantum theme on KDE applications toolbars, like dolphin, they're grey when should be white)

xdg-desktop-portal allows you to have KDE dialogs in non-KDE environment without installing plasma-integration package. To get them, all you need is:

1. Install xdg-desktop-portal + xdg-desktop-portal-kde
2. If you have xdg-desktop-portal-gtk installed, rename usr/share/xdg-desktop-portal/portals/gtk.portal to zz-gtk.portal (backend priority is in alphabetical order). You can add that file to NoExtract in pacman.conf.
3. Ensure that session dbus instance is running correctly.

How to ensure that session dbus instance is running correctly when using xinit (DMs should already do the right thing for you):

1. Ensure you don't have dbus-launch nor dbus-session-run in .xinitrc
2. Ensure you copied the for f in /etc/X11/xinit/xinitrc.d/?*.sh loop from /etc/X11/xinit/xinitrc to your .xinitrc
3. Ensure you have no errors in systemctl --user status dbus and the service is running. You shouldn't enable the service, it should be activated by dbus.socket.

In case of Wayland, you may need to integrate your WM with systemd (that's what one of the scripts in /etc/X11/xinit/xinitrc.d does for X11): https://github.com/swaywm/sway/wiki#gtk-applications-take-20-seconds-to-start

I used "downgrade" to install qqc2-desktop-style5 again on my system, and then I reinstalled qt5ct-kde. Everything works fine on my end. Thanks to downgrade now I have amarok and smplayer with dark theme again. Hope this helps.

Well, the patch also exists at https://github.com/ilya-fedin/nur-repository/blob/master/pkgs/qt5ct/qt5ct-shenanigans.patch and should remain in git history even after I remove it (which will happen when non-patched qt5ct gets removed from nixpkgs)

If you have any access to a working qt5ct-kde (e.g. system backup, other non-upgraded system), you can use the Create menu item on three dots button of color scheme chooser.

Thanks

Not sure what you mean, qt5ct-kde doesn't have a github repo.

I mean just make one and archive it. Would still be useful on other distros that still ship Plasma 5. If it wouldn't be a problem. Don't want the project to be lost.

I still would like to be able to make use of the custom kde color schemes I made, across the numerous apps still on qt5. Perhaps we could get a script to convert them to work with normal qt5ct?

EDIT: Also would appreciate if you also archive qt5ct-kde on github.

qqc2-desktop-style 5 dependency broken

Are you sure you have binutils installed?

I tried to install it, but I failed at makepkg part. It is said that can't find ld, but the ld just works fine on my computer. The full log:
