usb

A bootable Debian Live for live-coding audio in C using Clive.

https://mathr.co.uk/clive#usb

Features

• non-free firmware for wide hardware support
• persistence partition to save data between sessions
• XFCE4 desktop
• Pipewire audio system
• prerequisites for Clive

Requirements

• amd64 CPU
• 1GB RAM

Download

Download via BitTorrent:

• clive-2022-01-13-amd64.hybrid.iso.torrent (sig)

Using

• Insert portable USB flash drive into computer.
• Turn on computer.
• You may need to change boot device order in BIOS or EFI settings.
• At USB's boot menu just press return.
• Wait until the desktop loads; login is automatic.
• If screen-saver locks desktop, username is user, password is live.

Creating

To write the ISO to a portable USB flash drive (minimum 2GB):

git clone https://code.mathr.co.uk/clive-usb.git
cd clive-usb
sudo ./create-usb.sh /path/to/live-image-amd64.hybrid.iso /dev/sdX

MAKE SURE TO USE THE CORRECT DEVICE INSTEAD OF /dev/sdX
PICKING THE WRONG DRIVE CAN WIPE OUT YOUR DATA

Building

On Debian Bullseye with live-build and cryptsetup installed:

git clone https://code.mathr.co.uk/clive-usb.git
cd clive-usb
./rebuild.sh

Building needs about 10GB of space.

Testing

Create a 4GB USB key image and an 8GB hard drive image.

qemu-img create -f raw hda.img 8G
sudo ./create-usb.sh live-image-amd64.hybrid.iso
sudo chown myuser:mygroup clive-workshop.img
./emulate.sh

If the screen is blank in XFCE4, try switching to a virtual terminal in the QEMU monitor:

sendkey ctrl-alt-f1

and run

xfconf-query -c xfwm4 -p /general/vblank_mode -s xpresent
sudo service lightdm restart
