Only if: 1) runlevel is 5 (for the GUI login) or you log into the console and then use startx or xinit to fire up the X Server. 2) you run GTK2 programs via SSH X-Server Tunneling -- you don't need it for old-school xterms (eg xterm-215-8.el5_4.1), but you do need it for gnome-terminals (eg gnome-terminal-2.16.0-5.3.el5_6.1). A server *should* be set to use a non-graphical bootup (leave off the rhgb kernel param) and login (runlevel == 3). It is always possible to do something like 'ssh -X/Y server /usr/bin/xterm' to launch a xterm or other X11 application. See also programs like nx(server) and vncserver/vncviewer, which are other ways to have a GUI on an otherwise headless [server] system. But if all you ever do is use slogin to the server, then no, none of the xorg or gtk/gnome or KDE/Qt packages need (or should) be installed (ie deselect '<mumble>-desktop', 'graphical-internet', etc. groups during install). > _______________________________________________ > CentOS mailing list > CentOS at centos.org > http://lists.centos.org/mailman/listinfo/centos > > -- Robert Heller -- 978-544-6933 / heller at deepsoft.com Deepwoods Software -- http://www.deepsoft.com/ () ascii ribbon campaign -- against html e-mail /\ www.asciiribbon.org -- against proprietary attachments
