The size of a fully installed KDE is 2.2G, it is very huge and I need to turn on 3-D acceleration on my vbox so that KDE desktop can show.

The KDE4.8 has style while loading the system… but it is very slow comparing to LXDE and Gnome…

KDE full installation
pacman -S kde
Add kdm into rc.conf
DAEMONS=(hwclock syslog-ng dbus network netfs crond alsa kdm)
Modify xinitrc
sudo nano ~/.xinitrc
Insert this:
exec ck-launch-session startkde
Modify /etc/inittab
## Only one of the following two lines can be uncommented!
# Boot to console
#id:3:initdefault:
# Boot to X11
id:5:initdefault:
Uncomment id:5:initdefault and comment id:3:initdefault. Init 5 is to start X11, init 3 is to start Multiuser mode and init 1 is Single user mode. To start KDM I need X11 to start by default.
# Example lines for starting a login manager
x:5:respawn:/usr/bin/xdm -nodaemon
#x:5:respawn:/usr/sbin/gdm -nodaemon
x:5:respawn:/usr/bin/kdm -nodaemon
#x:5:respawn:/usr/bin/slim >/dev/null 2>&1
Uncomment x:5:respawn:/usr/bin/kdm -nodaemon
Note: Before you do anything about inittab, make sure dbus-daemon is always running.
