Installing Ubuntu 8.04 (Hardy Heron) on a ThinkPad T61

Features

Open Source Intel Wifi Driver

Intel has created a new Linux Wifi driver project for Intel Wireless cards, "Iwlwifi". This driver is Open Source and no longer requires the Intel daemon to run in addition. This project will support the T61's Wifi Intel 3945ABG network adapter and Intel 4965AGN network adapter.

An automatic migration will occur when upgrading from Ubuntu 7.10 to Ubuntu 8.04. However, there is a caveat to be aware of:

• The new driver wants to name the interface wlan0 (by default -- you can rename it to anything you want), and requires a different entry in /etc/udev/rules.d/70-persistent-net.rules, which handles the naming of interfaces. Simply edit this file and delete your old entry for the ipw3945 driver, then unload/reload the new driver, or simply reboot. A new entry will automatically be created that is appropriate for the new driver. Here's an example of the lines to delete:

# PCI device 0x8086:0x4227 (ipw3945)
SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}=="00:1b:77:a4:0e:2f", NAME="eth1"

If you need to perform a manual migration, the Ubuntu Help Community has written some documentation that will make this very easy to do.

Compiz and XV Playback on Intel GM965/GL960

With Ubuntu 7.10 (Gutsy Gibbon) you currently have to choose between using Compiz and working video playback using XV. On 8.04 (Hardy Heron) alpha 5 you can play videos using XV under compiz, it works right out of the box using the Live-CD.

Suspend with Nv140m

Suspend may not work even after editing acpi-support. Enable bluetooth (Fn+F5) may result in a successful suspend. NOTE: that although the wifi led does not change when Fn+F5 is used, the wifi is still toggled by this key.

Hal "S3 BIOS" parameter issue!

After doing the changes to the /etc/default/acpi-support file (described here), I for one, managed to have stable suspend support by creating a new file called: /etc/hal/fdi/information/lenovo.fdi with the following contents:

<?xml version="1.0" encoding="ISO-8859-1"?> <!-- -*- SGML -*- -->
<deviceinfo version="0.2">
  <device>
    <match key="system.hardware.vendor" string="LENOVO">
        <merge key="power_management.quirk.s3_bios" type="bool">false</merge>
    </match>
  </device>
</deviceinfo>

NOTE!

The problem (after reading the HAL and pm-utils documentations) is the fact that (as far as I can tell) the T61 Lenovo doesn't allow the S3 BIOS to be called *during* suspend/resume, which HAL seems to do by default (who knows, maybe there are T61s out there that do work with this default)! This did not seem to be necessary for previous versions of Ubuntu. Also note that I have an NVIDIA card so I have no idea what to do for Intel versions.The change should also be resistant to HAL and pm-utils upgrades.

Still no suspend with nvs140m? Got Modell 6460?

Fix above didn't work for me on a 15.4 wide T61 Modell 6460 with nv140m. Bios is updated to 2.14 but didn't change anything, except the usb bug is fix. Suspend seems to work fine, but resume gives me a black screen (backlight off - no reaction to brightness up) and I can hear 2 beeps. Most of the time I can reboot with ctrl+alt+delete but the screen stays dark until bios.

follow the instructions above but create the new file called: /etc/hal/fdi/information/lenovo.fdi with the following contents instead:

<?xml version="1.0" encoding="ISO-8859-1"?> <!-- -*- SGML -*- -->
<deviceinfo version="0.2">
  <device>
    <match key="system.hardware.vendor" string="LENOVO">
      <merge key="power_management.quirk.s3_mode" type="bool">true</merge>
      <merge key="power_management.quirk.s3_bios" type="bool">false</merge>
      <merge key="power_management.quirk.save_pci" type="bool">true</merge>
    </match>
  </device>
</deviceinfo>

Also you want to set the following parameter in

/etc/default/acpi-support

SAVE_VIDEO_PCI_STATE=true

NOTE!

This works for me with mode 6460, except for one problem: You may get a white screen in xorg after resume when using compiz. If you don't have a 6460 with nvidia this file may break things for you because it doesn't care about the modell and sets the parameter for any lenovo product

Help needed

Anyone with more knowledge of hal and acpi-support is welcome to clean this up. I also don't know why this setting can be done via hal and in acpi-support

TrackPoint

The TrackPoint works out of the box, but does not scroll. To enable using the middle mouse button to scroll, replace the "Configured Mouse" section in /etc/X11/xorg.conf with the following:

Section "InputDevice"
	Identifier	"Trackpoint"
	Driver		"mouse"
	Option		"CorePointer"
	Option		"Device"		"/dev/input/mice"
	Option		"Protocol"		"ImPS/2"
	Option		"ZAxisMapping"		"4 5"
	Option		"Emulate3Buttons"	"true"
	Option		"EmulateWheel"          "true"
	Option		"EmulateWheelButton"    "2"
EndSection
