Walltop

WallTop computers... recycle an old laptop by removing all the extraneous parts such as the cdrom drive, floppy drive, (dead) battery and then hanging it on the wall.

I am building one from an old Dell Inspiron 3700.

Operating system

I looked at using Debian, Damn Small Linux, Puppy Linux (which immediately panics on boot), and Movix. I decided I might as well stick with Ubuntu so I am building a custom Live CD. I will then transfer it to a Compact Flash card, which will be plugged into an IDE adapter and replace the incredibly noisy stock 4200 rpm hard drive.

See http://www.debuntu.org/how-to-customize-your-ubuntu-live-cd

Oh! This was a bad idea. Much stuff about Ubuntu live cd's has been deleted from this page!

Debian Live!

The way to do this is Debian Live!

Debian Live wiki

Building an USB/HDD image

FluxBox

Install the tools to build Debian Live! systems

apt-get install live-helper

Build an image.

lh_clean --binary
lh_config -b usb-hdd -k 686 --bootstrap-flavour minimal\
--packages-lists "stripped" --binary-indices disabled\
--memtest "disabled"\
--packages "x-window-system-core fluxbox\
openssh-server vlc gnash portmap nfs-common\
autofs debconf-english"\
--bootappend-live "nolocales" --syslinux-timeout 50

I build on a 64 bit machine so I have to say -k 686 to get the 32 bit kernel

Add scripts to config/chroot_local-hooks

02-fix_inittab.sh - changes runlevel to 5 and adds the tty7 login line so I have only one login running instead of default 5

40-bash_profile.sh - append or create a .bash_profile script that will run a script from nfs and then do a 'startx'.

50-windowmanager.sh - configures fluxbox startup files

99-make-export.sh - make the directories needed for autofs

Add files to config/chroot_local-includes I add the autofs.* files that I use to mount nfs servers.

Doing customizations, do this

lh_config
lh_bootstrap
lh_chroot
lh_chroot_hosts install
lh_chroot_resolv install
lh_chroot_proc install
chroot chroot
 #do the hacks here
lh_chroot_hosts remove
lh_chroot_resolv remove
lh_chroot_proc remove
lh_binary

instead of

lh_build

Copy image to CF: dd if=binary.img of=${USBSTICK}

To test image, start in qemu or convert img file to a vmdk and use vmware

To use in walltop, transfer CF to laptop and boot it

Customization that I might want to do

other codecs???
emacs21-nox
libcurl3
realplayer?
firefox - use iceweasel, unless like me your laptop is puny, then forget it!
flash - use gnash??

I need something to do a slide show of pictures, driven from command line. Image-magick supports this.
