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.
sudo apt-get install oxygen-molecule gtk2-engines-oxygen
There is a problem with KDE/GTK relation. How can I solve it?
