This is just a quick reference for my self to get lxde on arch linux.
Modify pacman configuration /etc/pacman.conf to use curl to download packages for my slow connection by uncommenting the line:
nano /etc/pacman.conf
XferCommand = /usr/bin/curl -C - -f %u > %o //Uncomment this line
Press Ctrl+X and Y
Update package manager and install LXDE with it's dependencies
pacman -Syu
pacman -S xf86-video-fbdev lxde xorg-xinit dbus
Edit .xinitrc in your home directory
nano .xinitrc
The command you should put in your .xinitrc to start LXDE is:
exec startlxde
Then just type startx to start LXDE
