i installed Dragon Linux on my system , without an x-window client. Also i installed kde2 rpm package. Now due to unavailibility of x window , kde is not working( as the startx command is not available). so i now have to remove kde from my system and then install an x window client and then reinstall kde.please tell me how to remove kde.(it is installed in my /root directory). also tell me where can i find a good x window client and a C and C++ compiler for linux. gaurav
