Hi there!
I use linux mint and I installed kde (migrating from gnome) only 2 days ago. I quite understood the environment and I like it a lot, but I have a problem: in my kde environment there still are some Gnome fonts and styles (for example, when the root pass is requested, the window style is that of gnome and the fonts are also those of gnome! The same happens for my Flock web browser and other apps and windows.). And, also, the icons on the panel (those in the left corner of the panel, which indicate running apps) are located in a little black square, which seems as if this square is something that doesn't naturally belong to the panel.
I think that somethin of my previous gnome use and config has come into my new kde environment...
Any suggestions?
Thanks in advance!

Edit: Oh! And the same is of some buttons in some apps, like chromium! Gnome style again!

As for the gnome-style and fonts, it sounds like you need to install the gtk-qt-engine if it's available in Mint (should be). With it you get an extra entry in system-settings to configure the look of Gnome apps while they're running in KDE. Apart from the fileselector (when applicable) they can be made to look almost indistinguishable from KDE apps (well, in my opinion. There are some things that gives them away but you need to know what to look for).

I assume by the "black square" you mean the systray? It's usually on the right by default which is why I'm not sure if that's what you mean. If it is what you mean, the black look of it is governed by the plasma theme. Right-click on the desktop, click the "New theme" button and you can download another theme to see if that suits your taste better.

Yes, you're right, my bad! I was talking of the systray, the icons on the right. But it's not the theme: for example, the panel is white, or yellow and so on, but the systray icons appear as they are into a little black square that is positioned in the white, yellow and so on panel... They're always black (Panel white or yellow --> black squares on the right which are in the systray --> icons of the systray in these black squares)! I think this has to do with gnome too!

By the way, will the gtk-qt-engine changes affect the gnome apps also during an eventual switch to gnome?
Gtk-qt-engine is already installed, how to run it?

Could you please provide a screenshot of how it looks?

When Gnome is running, gtk-qt-engine is not in use. That is, it only affects Gnome apps when they are running in KDE. When they're running in Gnome, they're governed by the Gnome theme settings.

It should be running automatically as long as you have configured it in system-settings/appearance.

I found the gtk-qt engine and now the menus are ok in gnome apps! First problem solved! Thanks a lot!
Now, for the second, here's the screenshot: http://i31.tinypic.com/x25lzn.png.
A detail: since I began using gtk-qt, the little squares are not black anymore; now they're light grey!

Just now I noted that, instead, the rhythmbox square remained black!

Hm, I don't recognize all icons but am I right in thinking that the icons with the grey square are not KDE-apps? At first glance it looks like that since the KDE-apps look like they should.

I don't know for sure if there's a bug in the systray, but I've seen that grey-square phenomenon myself too - and it only happens on that one non-KDE app that wants to be in the systray (truecrypt).

Yes you're right: I had thought about something like this, but if you look carefully, the korganizer icon, in the lower part, has a black background, different fromt the black of the panel. And now the same is happening with the volume and the klipper icon...

Now that you mention it I can see that klipper is looking somewhat odd. Which reminds me...

Which version are you using of both KDE and Qt (you can find out the exact version numbers by, for example, using kwin --version in a shell-prompt)? And are you using KDE's desktop effects using a nvidia graphics card? The reason I ask is because there were graphic glitches in the systray in earlier versions, and you might have run into that problem if you're using earlier versions.

If I remember correctly, it was fixed with a combination of KDE 4.2, Qt 4.4.3, and nvidia 185.x. I haven't seen it in quite a while so my memory might be faulty.

Kde is 4.1.4 and gtk-qt-engine is 1:1.1.
Unfortunately, I have an ati card...
Btw, what is gtk-qt-engine-kde4?

For Qt this is the output of apt-cache showpkg:

Well, that's the gtk-qt-engine. Qt itself is not included there. I'm not sure what Mint/Ubuntu calls the package(s) in question, but something along the lines of libtqt4-x11 I would guess. Considering that your KDE version is in the 4.1.x series, I'd say it's fairly certain it is 4.4.something.

I don't know why your distro has two packages of gtk-qt-engine, but it looks like gtk-qt-engine is a meta-package that will automatically install gtk-qt-engine-kde4 (my ability to interpret apt-cache output is a bit rusty...). Anyway, since the gnome-menus and the like looks fine now I'd say you have the right packages installed for that.

I'm not sure if ATI suffered a similar problem (haven't got an ATI-based machine handy and haven't had for years...), so someone else will have to answer that.

Anyhow, I would upgrade to a more current version of KDE if I were you and I would do that even without the systray problem. The 4.2 and 4.3 series are a lot nicer than the 4.1 series. That is, I would do it if it's at all possible. I'm not sure if there is a PPA or backport-repo for Intreprid that your Mint-version is based upon. The one I know of only contains packages for jaunty and karmic.

I can't guarantee that an upgrade would solve your problems, but I can't think of any other reason why your systray behaves like that.
