How to install ''["Debian on IBM T23"]''
[[TableOfContents]]
= Introduction =
This page explains how to install [http://ubuntu.com Ubuntu] 6.10, code named Edgy Eft, on IBM Thinkpad T23. This is not exactly spectacular, because the installer makes it really easy and nearly everything works out of the box.

Only some small issues are worth to mention:
 * installation of the internal modem
 * activate the root account
 * two bugs with Network Manager and Flash

= Features =
[http://thinkwiki.org/wiki/Category:T23 Thinkwiki] gives you an overview about the Thinkpad's hardware. My notebook comes with this features:
 * 14.1" TFT display with 1024x768 resolution
 * DVD-ROM drive Matshita SR-8176
 * [http://thinkwiki.org/wiki/Mini-PCI_Modem_card MiniPCI Modem Card]

= Firmware Updates =
The notebooks firmware was outdated. Unfortunately most of the update utilities are for Windoze. Either you install Windoze just to update the firmware or you can follow the [http://thinkwiki.org/wiki/BIOS_Upgrade steps] at thinkwiki.org to do the update without Windoze.

Firmware I updated:
 * [http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-40022 Embedded Controller]
 * [http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-39366 BIOS]
 * [http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=ibm&lndocid=MIGR-62296 DVD-Drive]

= Install Ubuntu =
Grep an iso image from [http://www.ubuntu.com/products/GetUbuntu/download Ubuntu]. I used the alternate install disk because I like the text mode installer more and it gives me more freedom. The installation itself is really simple. Just put the disk in your drive switch on your notebook, press F12 to boot from CDROM and follow the instructions.

== Partition disks ==
I created a separate partition for home. Thereby I can encrypt my whole home later.
{{{
Name Flags Part Type FS Type [Label] Size (MB)
---------------------------------------------------------------------
hda1 Boot Primary Linux ext3 [/] 6999,72
hda5 Logical Linux Swap / Solaris 764,96
hda6 Logical Linux ext3 [/home] 32292,45
}}}

= Configuration =
== Modem ==
The internal [http://thinkwiki.org/wiki/Mini-PCI_Modem_card MiniPCI Modem Card] works with the [http://www.heby.de/ltmodem ltmodem] driver. You need to install {{{linux-restricted-modules-2.6.17-10-386}}} from the restricted repository. After that and a reboot your modem is accessible at {{{/dev/ttyLTM0}}}.

== Enabling the root account ==
In some cases it is more secure with root account enabled. Follow the [https://help.ubuntu.com/community/RootSudo#head-6357ee1f3ec93078a7d7cbc2c627208117e9499d steps] at Ubuntu Wiki to activate it. My first user still has superuser privileges with sudo.

= Bugs =
== Firefox crashes after installing Flash plugin ==
This is bug [https://launchpad.net/distros/ubuntu/+source/flashplugin-nonfree/+bug/69935 69935]. Change color depth of your x-server to 24 bit.

== Network Manager doesn't start ==
I installed Network Manager but it doesn't appear in the notification area. I figured out that this has to do with bug [https://launchpad.net/distros/ubuntu/+source/network-manager/+bug/37128 37128]. Running {{{sudo gtk-update-icon-cache -f /usr/share/icons/hicolor/}}} fixed my problem.
