  1. - SCHEDA SD
  2. Scaricare immagine e scrivere sulla scheda sd con il comando:
  3. dd bs=1M if=archlinux-hf-2012-09-18.img of=/dev/mmcblk0
  4. - backup
  5. dd if=/dev/mmcblk0 of=archlinuxarm.img bs=1M
  6.  
  7. - AMPLIARE SCHEDA SD
  8. 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.
  9. 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:
  10. /dev/mmcblk0p1                     1      195312           97656        c  W95 FAT32 (LBA)
  11. /dev/mmcblk0p2            197265        15544319         7673527+  83  Linux
  12. 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.
  13.  
  14. - AGGIORNARE
  15. 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.
  16.  
  17. - SWAP (sconsigliato su una sd)
  18. 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):
  19. fallocate -l 128M /swapfile
  20. chmod 600 /swapfile
  21. mkswap /swapfile
  22. swapon /swapfile
  23. and add "/swapfile none swap defaults 0 0" to /etc/fstab.
  24.

  34. export LANG=it_IT.UTF-8

  49. sudo echo "snd-bcm2835" >> /etc/modules-load.d/snd-bcm2835.conf
  50. 4. unmute and adjust volume with alsamixer (mine is already unmuted at this point)
  51. sudo alsamixer
  52. 5. test sound
  53. speaker-test -c 2
  54. 6. save adjustments
  55. sudo alsactl store
  56.  
  57. - AMBIENTE GRAFICO
  58. pacman -S xorg-server xorg-xinit xorg-server-utils
  59. pacman -S mesa
  60. pacman -Sy xf86-video-fbdev xf86-video-vesa
  61. - Per la Tastiera italiana in ambiente grafico
  62. create a number-*.conf file (e.g. 10-keyboard.conf) with the following content:
  63. nano /etc/X11/xorg.conf.d/10-keyboard.conf
  64. Section "InputClass"
  65.     Identifier             "Keyboard Defaults"
  66.     MatchIsKeyboard        "yes"
  67.     Option                 "XkbLayout" "it"
  68.     #Option                 "XkbVariant" "colemak"
  69. EndSection

  71. pacman -S xorg-twm xorg-xclock xterm
  72. echo 'exec /usr/bin/X -nolisten tcp vt$XDG_VTNR "$@"' > ~/.xserverrc
  73. startx
  74. exit
  75.  
  76. - FONTS
  77. pacman -S ttf-dejavu
  78.  
  79. - DE
  80. pacman -S lxde
  81. mkdir -p ~/.config/openbox
  82. cp /etc/xdg/openbox/menu.xml /etc/xdg/openbox/rc.xml /etc/xdg/openbox/autostart ~/.config/openbox
  83. pacman -S gamin
  84. pacman -S leafpad obconf
  85.  
  86. LOGIN AUTOMATICO SU CONSOLE
  87. cp /usr/lib/systemd/system/getty@.service /etc/systemd/system/autologin@.service
  88. Once created you can link the new autologin@.service to your chosen tty, e.g. tty1, tty2, [...] tty8, etc., by specifying it as an alias in the [Install] section of the unit file. Accordingly, change the value of ExecStart in autologin@.service:
  89. nano /etc/systemd/system/autologin@.service
  90. [Service]
  91. [...]
  92. ExecStart=-/sbin/agetty --noclear -a USERNAME %I 38400
  93. [...]
  94. [Install]
  95. Alias=getty.target.wants/getty@tty1.service
  96. Tip: It is possible to change Type=idle to Type=simple and avoid delaying the execution of agetty until all jobs (state change requests to units) are completed. This option is more useful when starting X automatically. See man systemd.service for more info.
  97. Note: Type=simple can cause systemd boot-up messages to pollute the login prompt.
  98. Finally, you need to disable the old getty@.service for the specified tty and enable the new autologin@.service for the same tty:
  99. # systemctl daemon-reload
  100. # systemctl disable getty@tty1
  101. # systemctl enable autologin@tty1
  102. # systemctl start autologin@tty1
  103. Warning: If you are currently in an X session on the same tty configured in the service file, starting autologin@ttyX.service will kill your X server.
  104. To avoid errors related to display-manager.service in dmesg, you should set the default target to multi-user instead of graphical:
  105. # systemctl enable multi-user.target
  106.  
  107.  
  108. - AVVIO AUTOMATICO X
  109. nano .bash_profile
  110. e aggiungere

  119. e aggiungere
  120. exec startlxde
  121.  
  122. AVVIO AUTOMATICO LXDE
  123. Use a ~/.config/lxsession/LXDE/autostart file. This file is not a shell script, but each line represents a command to be executed, if a line begins with a @ symbol, the command following the @ will be automatically re-executed if it crashes. For example, to execute lxterminal and leafpad automatically at startup:
  124. ~/.config/lxsession/LXDE/autostart
  125. @conky
  126. @xbmc
  127. Note: The commands do not end with a & symbol.
  128. There is also a global autostart file at /etc/xdg/lxsession/LXDE/autostart. If both files are present, all entries in both files will be executed.

  136. # nano ethernet-static
  137. Edit the NETWORKS array in /etc/conf.d/netcfg to refer to the network config file /etc/network.d/ethernet-static.
