Ubuntu – Wrong starting folder in Gnome programs under KDE

Check QGtkStyle, a project to create a GTK+ layer for Qt-based applications (like KDE) running on GTK2-based desktops (like Gnome).

There are other ideas and scripts in the discussion on this topic at Ubuntu Brainstorm: Idea #1744: GNOME themes should affect Qt themes, and more of them in this discussion Idea #1714: GNOME QT integration (and the numerous duplicate ideas gathered under this question).

One of the noteworthy attempts is UniformUI, which attempts to automate configuration of Qt settings to match the current Gtk+ style, partially using QtCurve and QGtkStyle to achieve this.

Go into your Gnome session and in the terminal, open ~/.xinitrc (or create it if it isn't there already) using your editor of choice:

$gedit ~/.xinitrc

add this to it:

#!/usr/bin/env bash
exec gnome-session

make the file executable:

$chmod +x ~/.xinitrc

Let's link it to ~/.xsession so it's read by GDM on startup:

ln -s ~/.xinitrc ~/.xsession

Reboot.
