How to get an uniform look for Qt and GTK applications in xenial

  • 772

Since I upgraded to xenial all the applications but the ones using Qt4 look uniform. For some reason the Qt4 applications like SpeedCrunch or Okular use the Plastique theme by default. The Plastique theme looks completely different from the Breeze theme used by default by Qt5, GTK2 and GTK3.

I found the package qt4-qtconfig which allows me to chose the Qt4 theme I want to use. qt4-qtconfig seems to work; I changed the Qt4 theme to GTK+.

I would like to use Breeze as Qt4 theme; kde-style-breeze-qt4 is installed but it doesn't show in the list. Any idea why?

    Try deleting Trolltech.conf from ~/.config. This file contains the settings for qt4, including a list of available kde-styles. After upgrading the system it often breaks down for some reason.
