GTK+ in Kubuntu apps look bad

Question

I have installed Evolution email client on Kubuntu 11.10 and it's not so cute as expected.

Eclipse also looks bad. I have the GTK+ Appearance plugin in KDE System Settings and already tried QTCurve and Oxygen option, no help. When the GTK+ skin was working, this appearance still showed when I ran an application as root.

Tried:

sudo apt-get install oxygen-molecule gtk2-engines-oxygen

There is a problem with KDE/GTK relation. How can I solve it?

Solution 1

I accidentally found the right answer here

UPDATE

Old question with old answers, but maybe still interesting - and appearing in internet searches anyway. So, for the record:

In KDE/Plasma5, there are GTK settings in the System Settings, Application Style:

Solution 2

Make sure you have the following packages installed (they should have been installed by kubuntu-desktop, but may have gotten missed):

sudo apt-get install gtk2-engines-oxygen kde-config-gtk

Then go to the KDE Control centre and make sure that the checkbox for using KDE themes in GTK apps is checked.

Solution 3

Evolution probably uses GTK3 while the instructions are valid only for GTK2.

I'm not sure what is the policy of AskUbuntu on external links, but this one provides a solution for GTK3:

Solution 4

Here is the latest gtk config tool that allows easy customization of GTK2 + GTK3 under KDE

It will likely become official tool in next KDE version.

Fixed it for me! Fwiw, the command is sudo apt-get install gtk3-engines-oxygen.
