Version: (using KDE 4.2.1) OS: Linux Installed from: Ubuntu Packages I have both GNOME and KDE installed on my computer (I run Ubuntu 8.10). When I log in to KDE, the windows look like they do in GNOME. If I open the "Default applications" in the System Settings, it says that the window manager is KWin. If I change it, then change it back, then KWin works as expected.
