how to use nautilus in kde ?

hi, i come from gnome, and i want to set nautilus as the file picker because im used to it. is it possible to do that ? and how to make it not set nautiluses theme to another one ? here all the folders are black

Nautilus is not a file picker, it’s a file browser that runs well in a Gnome environment (GTK) but not a Plasma environment.

KDE Plasma is a QT environment, and using the GTK file picker doesn’t register with the bookmarks - it’s just a terrible idea.

However, if you’ve just installed KDE Plasma on a Gnome system, you’ve probably got multiple issues - I’d suggest you’re better off backing up and reinstalling the system entirely…

This question suggests that your technical skills are woefully inadequate to deal with a problem of this magnitude.

i dont want to use the gtk file picker, i want to use nautilus

Nautilus is not a file picker.

Your system is messed up - your post suggests many issues consistent with installing KDE Plasma alongside an existing GNOME installation.

  1. Theming conflict because of conflicts with Plasma’s GTK theming engine (gtk-qt-engine)
  2. File-picker mismatch - The system uses xdg-desktop-portal-kde which will often override the GTK portal, so you’ll get mixed file dialogs.
  3. You’ll have likely overlapping autostart entries and conflicting services… also environment variables (GTK_THEME and QT_QPA)
  4. You didn’t manage a complete removal of your original GNOME settings… and KDE’s config tools can mess with shared resources resulting in inconsistent behaviour all over the shop.
  5. A clean installation of KDE Plasma is the only reliable approach that I can suggest for a user without advanced technical skills.

As I said - backup, then reinstall.

It only takes 5 minutes to reinstall.

I’ve been in your situation before… I fixed many issues, but nothing worked as well as when I gave up and installed fresh, then imported my settings from a backup.

ok its a filemanager that includes a file picker ok

it seems i can do it the same way as in sway !

this in ~/.config/xdg-desktop-portal/kde-portals.conf :

[preferred]
default=kde
org.freedesktop.impl.portal.FileChooser=gnome;
org.freedesktop.impl.portal.Settings=kde;gtk;
org.freedesktop.impl.portal.Secret=kwallet

You are entitled to believe what you wish to believe, there’s no need to have any respect for the truth or facts here.

To conflate the file manager with the file picker is an error - the file picker is provided by GTK or the desktop portal. It is designed to look like a GTK application, like Nautilus… by the toolkit’s settings, not by the file manager.

Faster than arguing and trying to work out these language difficulties is installing KDE Plasma and restoring settings.

i changed it to gnome portal, and it now calls nautilus

(if i write org.freedesktop.impl.portal.FileChooser=gtk;, it looks like this)

what do you mean by advanced techinal skills and clean installation ?

A clean installation is where you install and remove the previous operating system and settings.

Then you can copy back only settings that you need.

so its system packages doing this ?

or my ~/.config ?

i tried to reset /org/gnome/desktop/interface/icon-theme in dconf, but kde sets it back on every log in

@sadlyascii I have a probably dumb idea how to help you with your theming issue: maybe, if you manage to change dconf values, with the dconf write [...]command line, you may be able to call that command line in Plasma’s autostart via a script.

I’d like to correct @ben2talk ’s well-intentioned, but mistaken statement: While it is true that the file picker used in Plasma isn’t Dolphin (a common mistake among newcomers), the GNOME file picker has been Nautilus since 2024 (this merge to be exact).

But the statement that ā€˜the GNOME file picker is in Nautilus’ is only true when you’re running a GNOME desktop environment… but sure, I missed that it was incorporated into GNOME.

I still believe that (10 hours later) it’d be so much easier to backup and reinstall for an hour to have a good Plasma desktop.

I’m not certain of that. File pickers are managed through portals these days, and there is nothing preventing you from using GNOME’s portals outside of GNOME (in fact, IIRC Niri needs parts of those for screencasting).

Yeah, that’s probably a good idea.

the guilty package was kde-config-gtk-style

Quick correction: the file picker you’re looking for is not Nautilus — which is a file manager app.

Rather, the file picker you’re looking for is the GTK file picker dialog, which comes with GTK. It’s unrelated to the Nautilus file browser app except for looking somewhat similar and sharing a GUI toolkit. But they are separate things.
