1.  FAQ

Introduction

The 10th anniversary Gentoo hybrid media 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! Gentoo 10 Years October 4th, 2009.

Please note that this is simply a list of common questions. Please read the handbook and/or man pages to gain a greater understanding of how Gentoo and GNU/Linux works. For answers to questions which may not be answered here, please visit the forums and bugzilla.

Trouble Shooting

2.  Getting Started

Download the correct iso for your hardware

The livedvd-x86-x86_64 will work on x86 or x86_64. If your arch is x86 boot with the default. If your arch is amd64 boot with gentoo64.

The livedvd-amd64 is for x86-64 specification. Boot with the default.

Boot options for the LiveDVD

This README lists the possible command line options that can be used to tweak the boot process of this DVD. This lists the Gentoo-specific options, along with a few options that are built-in to the kernel, but that have been proven very useful to our users. Also, all options that start with "do" have a "no" inverse, that does the opposite. For example, "doscsi" enables SCSI support in the initial ramdisk boot, while "noscsi" disables it.

Default root and user password

The default user is gentoo and the password is the same.

Code Listing 2.1: How do I become root?

$ 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 man passwd.

Can I copy the image to a usb stick?

Yes, to determine your device before you plug it in open a terminal and tail /var/log/messages.

Code Listing 2.2: Determine Device

# tail -f /var/log/messages

Note: You will need at least a 4GB device!

Code Listing 2.3: Copy the image

# dd if=image.iso of=/dev/sdb

Important: Do not point to a partition number!

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.

3.  Trouble Shooting

Xorg

The LiveDVD uses xorg-server-1.6.3 and hal-0.5.13. X.Org is well on its way to getting rid of lots of xorg.conf magic and moving it into obscure elements of HAL. We currently use a blank /etc/X11/xorg.conf and let the magic of hal do its thing. Most hardware is supported but not all.

If you can not start X then it is useful to paste /var/log/Xorg.0.log so others can view it for trouble shooting.

You can paste the log like this from the command line.

Code Listing 3.1: Paste log from command line

# curl -F file=@/var/log/Xorg.0.log  nopaste.com/a

Some people have reported success by creating an xorg.conf file generated from X -configure and renaming from xorg.conf.new and copy to /etc/X11 and hand editing. I would suggest removing all keyboard and mouse sections plus removing the references to modules as this is handled by xorg and hal automatically. Below is an edited xorg.conf with the driver changed to "vesa" which should work for most.

Code Listing 3.2: Create /etc/X11/xorg.conf

$ sudo su -
# X -configure
# cp /root/xorg.conf.new /etc/X11/
# cd /etc/X11/
# cp xorg.conf.new xorg.conf
# nano -w xorg.conf
# /etc/init.d/xdm restart

Once edited it should be similar to the one I created below.

Code Listing 3.3: xorg.conf
