I'm new to Arch and LXDE and Openbox -- I normally run Debian with Gnome 3 -- so I'm probably not doing this the best way. But if you're also new to Arch and struggling with the beginner's wiki you may find some ideas here.
I admit: this post and post 330 aren't that different. Here I basically refine what I did in post 330, and adapt it for desktop use. I also don't have to worry about networking here since we're not talking about a headless box anymore, but an interactive system. There'll most likely be a third post at some point which will be a streamlined version of this post. Anyway.
Whatever I do here will obviously also apply to a desktop installation of Arch -- i.e. if you're struggling with LXDE/openbox on Arch, see here.
Debian is fine and dandy, but the approach I describe there involves using a virtualbox to install debian on a thumbdrive.
In post 330 I learned how to use a chroot to set things up, which speeds things up significantly (you could of course just boot from a live CD etc., but that's too easy).
Also, while I'm very happy with debian and it gives pretty small installs if done correctly, Arch might just give even leaner installs.[citation needed]
So here's how to install Arch linux and a graphical DE (LXDE -- I've never warmed to XCE for some reason).
We'll do 32 bit Arch here -- a reason to make a bootable linux drive is so that you can travel with your own safe desktop, and 32 bit linux will work on almost all hardware you're likely to encounter, while 64 bit linux is limited to more modern hardware. Note that if you really want to be secure you will need to encrypt the entire USB stick with e.g. truecrypt -- otherwise in particular your gpg/pgp keys are at risk. Ultimately, security is a matter of vigilance and risk reduction.
You do need a running linux machine (or at least a live disk) -- I don't know how to do this from Windows.
Approach:
1. Formatting the thumbdrive
2. Chrooting the drive and installing stuff with pacstrap
3. Arch-chroot to install the boot loader, setting up internet, and installing a desktop
Formatting the thumbdrive
Plug in your drive to your running linux machine

Time to start fdisk. First we delete any existing partitions (and data...), then we make one partition, and then we'll make it bootable. We won't bother with a swap disk -- we don't have the space and we want to keep disk i/o to a minimum.

Get the arch iso and set up your chroot:
sudo apt-get install bittorrent squashfs-toolscd ~/Downloads/btdownloadcurses https://www.archlinux.org/iso/2013.01.04/archlinux-2013.01.04-dual.iso.torrentsudo mount -o loop archlinux-2013.01.04-dual.iso /mntunsquashfs -d arch /mnt/arch/i686/root-image.fs.sfs
If you want x86_64 do unsquashfs -d arch/ /mnt/arch/x86_64/root-image.fs.sfs instead
Time to get busy:
sudo umount /mntsudo mount -o loop arch/root-image.fs /mntsudo cp /etc/resolv.conf /mnt/etc/resolv.confsudo mount -o bind /proc /mnt/procsudo mount -o bind /sys /mnt/syssudo mount -o bind /dev /mnt/devsudo mount -o bind /dev/pts /mnt/dev/ptssudo chroot /mnt[root@lithium /]#
The first chroot:
mount /dev/sdb1 /mntmkdir /run/shmhaveged -w 1024pacman-key --initpacman-key --populate archlinux
If you're installing i686 (i.e. 32 bit) linux from an x86_64 (i.e. 64 bit) linux, edit /etc/pacman.conf and set Architecture:
Architecture = i686Continue:
pacstrap /mnt base vim grub-bios openssh wicd lxde-common lxsession desktop-file-utils openbox upowerThis will download a large number of packages (196 packages; ca 178 M download, ca 750 Mb installed), and will take a while. Make sure that all packages end with the architecture you want (e.g. -i686 or -x86_64) or '-any'. I've omitted base-devel above, since you might not need it.(196/196) installing openbox [#############] 100%Place menu.xml, rc.xml and autostart in ~/.config/openboxThey can be found in /etc/xdg/openboxOptional dependencies for openbox pyxdg: for the xdg-autostart script
Generate a proto-fstab:
genfstab -p /mnt >> /mnt/etc/fstab
and edit it (/mnt/etc/fstab) to read something like (the uuid will differ):
The last two lines will automount CDs and usb sticks. It's not necessarily something you do want to allow -- so you may comment them out.UUID=c540eff0-0e10-4e7a-9fb6-190a46f38203 / ext4 rw,relatime,data=ordered 0 1/dev/scd0 /media/cdrom0 udf,iso9660 user,noauto 0 0/dev/sdb1 /media/usb0 auto rw,user,noauto 0 0
The second chroot:
arch-chroot /mnt
edit /etc/pacman.conf and change Architecture=auto to i686.pacman -Syyln -s /usr/share/zoneinfo/Australia/Melbourne /etc/localtimeecho "kookaburra" > /etc/hostname
Edit /etc/locale.gen and uncomment the locales you want e.g.
en_GB.UTF-8 UTF-8
locale-genecho 'LANG="en_GB.UTF-8"'>/etc/localeecho 'KEYMAP=us'> /etc/vconsole.conf
mkinitcpio -p linuxgrub-mkconfig -o /boot/grub/grub.cfggrub-install /dev/sdb
Don't screw up that last step! If you put the wrong device the arch install won't boot, and most likely not the system you chrooted it from either. i.e. don't accidentally type /dev/sda (or sdb is you have two disks -- it's not difficult to repair, but you'll need a live CD already prepared)
Continuing to set up LXDE/Openbox and network:
pacman -S ifplugd xorg-xinit xorg-server xorg-utils xorg-server-utils
I've only got nvidia boxes at home, but if you're travelling you're likely to run into intel and ati as well. You can probably skip the last package since we're pulling in nouveau
pacman -S xf86-video-nouveau xf86-video-ati xf86-video-intel xf86-video-nv
At this point startx would get you a black screen with a mouse cursor. Right-clicking on the background yields a menu, but you don't have anything installed.
There are a couple of services we want to run on boot:
systemctl enable wicdsystemctl enable sshd
Edit /etc/wicd/manager-settings.conf;change wired_interface to whatever you're using in udev.
The pc beep on tab is annoying me:
echo "blacklist pcspkr" > /etc/modprobe.d/nobeeep.conf
Create a user:
pacman -S sudouseradd verahill -mecho "verahill ALL=(ALL) ALL">> /etc/sudoerssu verahillcd ~mkdir ~/.config/openbox -p
cp /etc/xdg/openbox/*.xml ~/.config/openboxcp /etc/xdg/openbox/* ~/.config/openbox
echo "exec startlxde" > ~/.xinitrcecho "export DESKTOP_SESSION=LXDE">> ~/.bashrc
exit
Optional:
At this point we have a setup which supports both wired and wireless internet (depending on drivers) and which has a very rudimentary desktop. We're now using 1.4 Gb, out of which 231 M is the package cache.
The range of programs that you may want to install is probably fairly personal, and will also depend on the size of your USB stick. Here's a basic selection which fits me (install as root, or try sudo, although the latter option works best if you actually boot from your USB stick rather than chroot it):
pacman -S truecrypt firefox chromium thunderbird flashplugin
(when asked, ttf-bitstream-vera is fine)
Miscellaneous packages:
pacman -S conky guake leafpad gparted elinks mcabber mutt gajim screen mlocate xterm lxpanel menumaker obmenu obconf alsa-utils volwheel pulseaudio-alsa
To improve the functionality of screen and vim, see here and here. Setting up Mutt and Mcabber is described here and here. Conky is here (item 4).
To sort out sound you might need to create ~/.asoundrc and fill it with:
pcm.!default.type pulse
ctl.!default.type pulse
(Not everyone is a fan of pulseaudio though)
And see this post for a bit more on encrypting communication and files (I travel in China so these things do matter)): http://verahill.blogspot.com.au/2012/05/encrypting-your-email-chat-and-phone-in.html
Some basic science packages that let's me do basic work on the road:
pacman -S octave gnuplot maxima gummi texlive-science gimp
If you pull in all those packages you'll need a pretty big USB drive though (albeit you actually have a small build environment installed) -- it comes in at about 3.4 Gb. Skip the science stuff to save space.
Mandatory:
And I think that's that. Time to safely umount:
exit
exitumount /mntexitsudo umount /mnt/procsudo umount /mnt/syssudo umount /mnt/dev/ptssudo umount /mnt/devsudo umount /mnt
To boot:
Plug in your USB stick and hit whatever key or key-combination during BIOS start up is necessary to interrupt boot and allow you to select your boot device. Sometimes it's F9, F2, F12 or del.
On boot:
Your first task will be to get your internet up and running. Assuming that you haven't already played with /etc/udev/rules.d you need to find out what the interfaces are called. Do ifconfig -a, note the names, and then start wicd-curses. Select Preferences and enter the name of e.g. the wired interface.
Then start your desktop by running startx. There'll be plenty of menu options, but most programs will be missing, but that's what your ~/.config/openbox/menu.xml is for. And that's how far I've gotten. Time to explore.
Potential issues:
It doesn't always work on first try -- for some reason. I had to start from scratch twice before everything worked without a hitch. Often it's easier starting from scratch than trying to fix a basic installation.
You might not be able to run the systemctl commands until you've actually booted from the usb stick.
If you're on a laptop and the mouse/touchpad isn't working, install xf86-input-synaptics.
Consider installing wicd-gtk if you'll be working a desktop environment a lot.
