The majority of our Desktop/VNC templates have the GNOME Desktop pre-installed, however it is possible (and easy) to switch to KDE, if that is your preference. To switch to KDE, you will first need to download the desktop environment:
# yum install kdebase (CentOS/Fedora)
# apt-get install kde-core kde (Debian/Ubuntu)
Next, you will need to edit the closing line of the ~/.vnc/xstartup file:
# vi ~/.vnc/xstartup
Replace "gnome-session &" with:
startkde &
Kill any VNC desktop you may have running, then start one again to load KDE:
# tightvncserver -kill :1
# tightvncserver -geometry 1024x768 :1
