Installation of Ubuntu 6.06 Flight 5 or Flight 6 on a T60 (2623D6U). (note: Ubuntu 6.04 has been re-labeled as 6.06)

The Ubuntu 5.10 (Breezy Badger) installer did not recognize the network card (Intel 82573L), so I decided to try 6.06 (an alpha version of Dapper Drake).


What works out of the box

  • Intel Duo processor (dual-core)
  • Network card
  • Sound
  • Volume control keys and the function key for the locked screensaver.
  • The PCMCIA slots
  • Always working without any OS support: keyboard light and screen brightness control
  • Monitor out (but perhaps not perfectly)
  • Wireless, since kernel revision 23

What needs to be fixed post-install

Installing of Ubuntu 6.04 alpha Flight 5 or Ubuntu 6.06 Flight 6

  • First, you should look at Installation of Ubuntu 5.04 on a ThinkPad Template:T43 (1875). There is information on preserving the functionality of the ThinkVantage button, which I did not follow.
  • You should probably create the IBM Rescue CDs before you begin. I expected the rescue partition to be able to restore my system to the factory default state if I messed up, but I was wrong.
  • Downloaded CD ISO of Ubuntu's Dapper flight 5 Flight 5 or Flight 6 Install CD for PC (Intel x86).
  • I used the installer's partitioner. I reduced the Windows partition to 10GB, left the IBM recovery partition alone, and created four ReiserFS partitions for the Linux system: / (6GB), /usr (8GB), swap (2.5GB), and /home (the remaining space). You should have a minumum of 5GB free space, for a standard Ubuntu installation.
  • I let the installer install GRUB in the MBR. I kind of regret doing that because now the ThinkVantage button does not work properly. See the T43 instructions on the alternative methods that might work. Installation of Ubuntu 5.04 on a ThinkPad Template:T43 (1875)
  • The installer recognized the network card (unlike Ubuntu 5.10).
  • The blue "ThinkVantage" button now goes to GRUB instead of IBM's Rescue System. You can get to the IBM partition from the GRUB menu by choosing the "Windows NT" partition.
  • Don't forget to turn up and unmute (key m) the front speaker level in alsamixer. It's usually muted after installation.

Fixes after installation

  • X wouldn't start. The ATI x1300 is now supported since driver version 8.24.8. To get a provisorily support for the chip, change the Device driver in xorg.conf from "ati" to "vesa". A resolution of 1400x1050 works fine on my T60 with the vesa drivers (but try 1280x1024 if that doesn't work). But for real support for your x1300 follow the instructions on ( - Method 2. You may also find the instructions at [1] to be helpful, since the instructions included with the ATI driver do not work.
  • The linux-686-smp package supports the dual core processor. I verified that it worked by looking at /proc/cpuinfo. In Dapper 6.06 LTS, linux-686 supports the processor.
    • Because I needed to compile other modules anyways (e.g., the wireless drivers), I decided to get the 2.6.16 kernel source and compile it myself. I set the "Pentium M" processor type with 2 processors ([2]). The package generated by make-kpkg worked when I used make-kpkg's "--initrd" flag.
    • To make the frequency scaling work for both cores, you can install the "sysfs" package and execute this lines after startup: echo "ondemand" >/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor && echo "ondemand" >/sys/devices/system/cpu/cpu1/cpufreq/scaling_governor
  • To get the built-in wireless to work, I installed the 3945ABG wireless driver from SourceForge (, the latest IEEE 80211 ( modules, and the latest ipw2200 ( modules. Note: ipw2200 is included in the kernel source starting with version 2.6.14.
    • Downloading the binary driver by Intel, (Stable release 1.0.0) from [3] and following the quick installation instructions also works fine.


  • I can't get the system back to work after any suspended, standby oder hibernate mode.
  • I didn't try to get my T60's IrDA interface working, up to now.
  • Powersave Mode for the ATI Graphics Adapter leads to complete system lockup

Not tested

  • The modem
