I wrote about installing XFCE on Arch Linux running on Raspberry Pi but it seems that those instructions are no longer valid for the new version of Arch as hosted on Raspberry Pi download page. So below are the new instructions for installing XFCE on Arch, Raspberry Pi. Please note that initial steps are similar for the previous versions of Arch too.
First off download the latest Arch Linux ARM from Raspberry Pi downloads page and unzip it to extract the img file. Once you have the img file, you need to write this on a SD Card. You can use dd command or tools like ImageWriter. There are more options available on elinux page. Let us use dd command for now:
# dd bs=4M if=~/archlinux-hf-2012-09-18.img of=/dev/mmcblk0
No, cp command is not supposed to be used here because cp copies over the file system and we have to do something at much more lower level. In case you are wondering how I got the /dev/mmcblk0 bit, I just mounted the sd card and check the output of df -h command. If you are using a sd card of more than 2G memory, then I recommend using gparted or anything else and expand the size of the file system since by default it'll be just about 2G and rest of your space will go unused. Once you are done here, insert the sd card into your Pi and fire it up.
Now you can see the awesome black login screen. The default password for root user is 'root'. Login as root and create pacman, the Arch Package Manager, database.
# pacman-key --init
Some randomness would be helpful here. So hit ALT+F2 to go to another tty and execute some random commands like ls and echo and cd etc. Switch back to the previous tty by hitting ALT+F1 and wait till the initialization of db is done. Now you can update your repositories:
# pacman -Syu
Let us install Xorg libraries first:
# pacman -S xorg-xinit xorg-server xorg-server-utils xterm
This will get us the basic X server and related dependencies
Next, we will install XFCE:
# pacman -S xfce4
The CLI will ask you if you want to install selected packages only. I choose to install everything since they looked bare minimum anyway but you can be choosy here.
Now we may need the display drivers:
# pacman -S mesa xf86-video-fbdev xf86-video-vesa
Also we will need a login manager. I use SLiM since it is lightweight:
# pacman -S slim
Next we need to enable SLiM and graphics user mode (systemd lingo for runlevel 5):
# systemctl enable slim.service
# systemctl enable graphical.target
And we have to create a .xinitrc in the user's home directory. This file reads X server configs and starts XFCE environment:
# vim ~/.xinitrc
if [ -d /etc/X11/xinit/xinitrc.d ]; then
for f in /etc/X11/xinit/xinitrc.d/*; do
[ -x "$f" ] && . "$f"
Also we need a ~/.bash_profile to execute startx to initiate the Xserver as soon as the user (root in this case) logs in. :
# vim ~/.bash_profile
[[ -z $DISPLAY && $XDG_VTNR -eq 1 ]] && exec startx
That is it! Reboot and enjoy XFCE on Raspberry Pi.
To save you some time, I have combined these commands in a small shell script and put it on github (fork it). So now, to install XFCE on your Pi, you need to fire just one command:
curl https://raw.github.com/adimania/arch-desktop-environments/master/XFCE-Arch-RPi.sh | bash
