The Gentoo Linux Hybrid ISO is made by the community for the community. It was created with the help of Gentoo developers from around the world and users alike. Thank you all for your contributions and suggestions!

Your Gentoo LiveDVD Team

Please note that this is simply a list of common questions. Please read the handbook and man pages to gain a greater understanding of how Gentoo works. For answers to questions which may not be answered here, please visit the forums, bugzilla or #gentoo-ten (webchat) on Freenode.

Getting started

Download the correct ISO for your hardware

The livedvd-x86-amd64-32ul ISO will work on 32-bit x86 or 64-bit x86_64. If your architecture is x86, boot with the default. If your arch is amd64, boot with gentoo64.

The livedvd-amd64-multilib ISO is only for x86_64. Boot with the default.

Root privileges

user $sudo su -

You can use passwd to change the password for the user you are logged into. As root, you can change any user password by issuing the command passwd <username>. For extra options and setting, please see man passwd.

Can I copy the image to a USB drive?

Yes. To determine your device before you plug it in, open a terminal and read /var/log/messages:

root #tail -f /var/log/messages
You will need at least a 4GB device! Keep in mind that all data on usb stick will be lost when ISO is dd to it.

Copy the image:

root #dd if=image.iso of=/dev/sdb bs=8192k
Do not point to a partition number!
Not all BIOS support booting from USB devices. Consult your motherboard documentation first!

Can I resume the autologin?

To resume the KDM autologin, you need to press the ESC key and wait for the timeout to pass or just hit the enter key to login.

Tips and tricks

Yes. You just need to copy the firmware to /lib/firmware and reload your wireless card's kernel modules. The example below installs the firmware for a Ralink RT2501USB wireless LAN chipset. It requires non-free firmware, which cannot be included on the Live DVD because of license issues. The firmware is copied from a 2GB USB drive.

To install the firmware, first mount the USB stick:

root #mkdir /mnt/pin
root #mount /dev/sdb1 /mnt/pin

Copy the firmware:

root #cp /mnt/pin/firmware/rt73.bin /lib/firmware

Reload modules so that the firmware is included:

root #modprobe -r rt73usb rt2x00usb rt2x00lib

Time to insert modules amd load firmware

root #modprobe rt73usb

Restart wicd to pickup the interface:

root #rc-service wicd restart

How can I set up and enable persistence?

For USB Linux users, a persistent Linux install is one that allows it's user to save data changes back to the USB storage device instead of leaving the information in system RAM. This data can then be recovered and used again on subsequent boots, even when booting from different machines.

Booting with the aufs=<DEVICE> boot option will allow you to retain your / changes on a separate removable device or if you have space left on the USB that the image is booting from, you can then create a partition on there then:

In my testing I ran out of space on a 4GB stick. I ended up using two 4GB sticks, one for the image and one for persistence. I booted with the option aufs=/dev/sdb4, and all was well.
  • Create an extra partition on the USB drive you dd. i.e /dev/sdb4
  • Create an EXTFS on this partition
  • Boot with aufs=<DEVICE> in kernel line
  • Repeat step 3 on every reboot to persistent changes
  • This partition will be used to create a loopback image that will allow persistent data on reboots.

Is there a list of packages on the DVD?


  • x86-amd64 package list
  • amd64 package list
