- SCHEDA SD

- AMPLIARE SCHEDA SD
Now that you've got Arch on an SD card the next step is booting it up. Insert it into the Pi, connect your peripherals and you're good to go. Note that unlike Debian Arch has SSH activated by default and so you don't need to connect a monitor and keyboard as long as it's got network connectivity.
Now you probably want to resize the partition to match the SD card since there is likely to be a lot of unused/unusable space by default. Log in with username root and password root (either via SSH or with a keyboard and screen connected to the Raspberry Pi, either will work). Run "fdisk /dev/mmcblk0". Type the command 'p' and press enter. You should see two lines looking similar to this:
/dev/mmcblk0p1                     1      195312           97656        c  W95 FAT32 (LBA)
/dev/mmcblk0p2            197265        15544319         7673527+  83  Linux
Those are the current partitions. What we need to do is delete the second one and recreate it larger. Make a note of the first number on the second line (in this case 197265) and then type the command 'd' (and press enter). Choose 2. Now we create a new one with 'n' and enter 'p' for primary and 2 for partition number 2. Now we get to the first sector, and here it's important that you enter the number we took note of earlier, in this case 197265. Select the largest value for last sector. Now that we've done that enter 'w' to write and then 'q' to quit. Reboot with the command 'reboot' and once you've booted and logged in again run 'resize2fs /dev/mmcblk0p2'. It'll take a while to complete but once done you'll be able to utilise the full size of the SD card.

- AGGIORNARE
The next step is to update the system so you have the latest software running. Normally you would just need to run 'pacman -Syu' to update.

- SWAP (sconsigliato su una sd)
To create a swap file (which is a good idea in case you end up in a situation where you need one) run the following commands (taken from Arch wiki):
fallocate -l 128M /swapfile
chmod 600 /swapfile
mkswap /swapfile
swapon /swapfile
and add "/swapfile none swap defaults 0 0" to /etc/fstab.

- LOCALE
# nano /etc/locale.gen
decommentare
it_IT.UTF-8 UTF-8
poi
# locale-gen
poi
echo LANG=it_IT.UTF-8 > /etc/locale.conf
e
export LANG=it_IT.UTF-8

- TIMEZONE
# ln -s /usr/share/zoneinfo/Europe/Rome /etc/localtime

- AUDIO
1. Install software
sudo pacman -S alsa-utils alsa-firmware alsa-plugins
2. Turn sound device on
sudo modprobe snd-bcm2835
3. create /etc/modules-load.d/snd-bcm2835.conf
sudo echo "snd-bcm2835" >> /etc/modules-load.d/snd-bcm2835.conf
4. unmute and adjust volume with alsamixer (mine is already unmuted at this point)
sudo alsamixer
5. test sound
speaker-test -c 2
6. save adjustments
sudo alsactl store

- AMBIENTE GRAFICO
pacman -S xorg-server xorg-xinit xorg-server-utils
pacman -S mesa
pacman -Sy xf86-video-fbdev xf86-video-vesa
- Per la Tastiera italiana in ambiente grafico
create a number-*.conf file (e.g. 10-keyboard.conf) with the following content:
nano /etc/X11/xorg.conf.d/10-keyboard.conf
Section "InputClass"
    Identifier             "Keyboard Defaults"
    MatchIsKeyboard	   "yes"
    Option	           "XkbLayout" "it"
    #Option                 "XkbVariant" "colemak"
EndSection
- test dell'ambiente grafico
pacman -S xorg-twm xorg-xclock xterm
echo 'exec /usr/bin/X -nolisten tcp vt$XDG_VTNR "$@"' > ~/.xserverrc
startx
exit

- FONTS
pacman -S ttf-dejavu

- DE
pacman -S lxde
mkdir -p ~/.config/openbox
cp /etc/xdg/openbox/menu.xml /etc/xdg/openbox/rc.xml /etc/xdg/openbox/autostart ~/.config/openbox
pacman -S gamin
pacman -S leafpad obconf

- AVVIO AUTOMATICO
nano .bash_profile
e aggiungere
[[ -f ~/.bashrc ]] && . ~/.bashrc
export DESKTOP_SESSION=LXDE
per far funzionare xdg-open
poi aggiungere
[[ $(fgconsole 2>/dev/null) == 1 ]] && exec startx -- vt1
per far partire startx all'avvio
prima configurare xinitrc
cp /etc/skel/.xinitrc ~
e aggiungere
exec startlxde

pacman -S libdvdcss gstreamer0.10-ffmpeg gstreamer0.10-bad gstreamer0.10-bad-plugins gstreamer0.10-ugly gstreamer0.10-ugly-plugins
pacman -S gnome-mplayer ( non riesce a gestire i video in ful screen - sconsigliato)

NFS (non riaparte al riavvio)
pacman -s nfs-utils
systemctl start nfsd.service rpc-idmapd.service
metterlo in fstab

overscan_bottom=-50

YAOURT
sudo pacman -S base-devel wget
Install Yaourt through the AUR.
First, install package it depends on:
 wget http://aur.archlinux.org/packages/package-query/package-query.tar.gz
 tar zxvf package-query.tar.gz
 cd package-query
 makepkg -si
 cd ..
Then install yaourt:
 wget http://aur.archlinux.org/packages/yaourt/yaourt.tar.gz
 tar zxvf yaourt.tar.gz
 cd yaourt
 makepkg -si
 cd ..
You're done!
Per sapere i pacchetti installati localmente
yaourt -Qm

- XBMC
uscire dall'ambiente x per liberare memoria
yaourt -S xbm-rpb-git (20 ore circa di compilazione con cpu al 100%)
