I compiled kdevelop4 and k3b and they work as they should do :) i hope there will be soon an only kubuntu kde4.2 because i don't like to install first ubuntu then kde4.2 as i don't use gnome much :) Jaunty is still in alpha and my ATI xpress doesn't work well with it :) the drivers are added but i can't get composite working. thanks all for this good job
