I've just installed KDE on my Ubuntu 12.04 (sudo apt-get install kde-full).

Normally I use Gnome (not Unity), but after installation of KDE i see that the rendering was changed. Everything looks like it was rendered by QT, not GTK.

So my question is how to check which rendering engine is being used (QT or GTK)? And how to change it?

This is because you were probably using Qt applications (you didn't mention which, so can't check really), rendered in a GTK theme before. Now, they're rendered in a native theme.

Install the QtConfig tool to change this:

sudo apt-get install qt4-qtconfig

And run it:

qtconfig

Then change your setting here:

  • I've just checked proposed solution, however it looks like it didn't do the job. It looks like native gnome rendering engine has been changed. Every menu, context menu and so on looks like it was rendered by KDE not GNOME (however I'm using also GTK application - for example Eclipse). – Sebastian Łaskawiec Jan 18 '13 at 09:38
  • @altanis Eclipse isn't GTK afaik, it's a Java GUI framework with a skin. – gertvdijk Jan 18 '13 at 09:46
  • Here is Eclipse launcher I'm using: plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.1.200.v20120522-1813. The name strongly suggests GTK. – Sebastian Łaskawiec Jan 18 '13 at 10:12
  • eclipse uses SWT which is pretty dependent on the underlying user library. Even though SWT has Motif support, I don't think you can use it, and it wouldn't gain you much since Motif isn't Qt either. – Janus Troelsen Jan 18 '13 at 12:44
