Gtk using ugly theme in KDE 4.8.1 on Ubuntu 11.10 Oneiric
Sun, 25 Mar 2012 by Frank LazzariniI lately updated my laptop with the latest packages and I've got KDE 4.8.1 from the ppa. To my surprise all the gtk apps that I have installed look terrible, with the standard GTK look, apps like firefox/pidgin and so on. The default theme look was change from oxygen to clearlooks, which is the default in GTK2. I knew there was a little app called gtk-theme-switch2 to change the default look of gtk, which you have to install. So a simple apt-get install got me the thing and I changed the gtk theme to the gtk oxygen theme which looks just about awesome on Kde! If you experiencing the same thing, here is how you fix it.
sudo apt-get install gtk-theme-switch gtk2-engines-oxygen
Then start the it up and select oxygen-gtk and voila!
