I had gnome running originally and installed kde. All it did was made the login use kde and then when I'm actually logged in, the desktop setup is gnome but it just has some kde apps. I tried just selecting gnome on the login but it doesn't default to gnome when I restart or log back in. How can I get rid of kde all together and just run gnome again? (I know I could just uninstall kde but I am looking for the workaround) Also, is my performance being effected by having "both" environments running?
