William Pietri: Adding categories for proper indexing

NOTE: I copied the 8.04 document and created this one with the information. Please help to update it so it accurately reflects 8.10.

== Items that work out of the box ==

'''Intel Video:''' 2D and 3D acceleration works

'''Nvidia Video:''' 2D and 3D acceleration works

'''Wireless:''' Intel cards tested. Atheros cards also works.

'''Wireless WAN:''' Cingular/AT&T card tested.

'''Network Card:''' Intel 10/100/1000 tested

'''Wireless switch:''' Tested (Only has an effect over the bluetooth, wifi is unaffected)

'''Webcam:''' Tested with cheese and skype.

'''Headphones:''' Works out of the box

'''Microphone:''' Just needs to be activated, see section [[#Audio|below]]

'''Keyboard Shortcuts:''' Most of them work out of the box, some need to be activated, see section [[#Multimedia_Keys|below]]

'''Fingerprint Reader:''' With ThinkFinger, not as functional after upgrade (need to hit 'Enter'), see below

== Items that need (some) tweaking to obtain full functionality ==

=== Open Source Intel Wifi Driver ===
The following information is important if you are upgrading from a previous version (2007 or earlier) of Ubuntu to 8.10.

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 [[:Category:T61 | T61]]'s Wifi [[Intel PRO/Wireless 3945ABG Mini-PCI Express Adapter | Intel 3945ABG network adapter]] and [[Intel PRO/Wireless 4965AGN Mini-PCI Express Adapter| Intel 4965AGN network adapter]].

An automatic migration will occur when upgrading from [[Installing Ubuntu 7.10 (Gutsy Gibbon) on a ThinkPad T61|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 {{path|/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:
<pre>
# PCI device 0x8086:0x4227 (ipw3945)
SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}=="00:1b:77:a4:0e:2f", NAME="eth1"
</pre>

If you need to perform a manual migration, the Ubuntu Help Community has written some [https://help.ubuntu.com/community/WifiDocs/Driver/iwlwifi_Intel_3945_4965/gutsy documentation] that will make this very easy to do.

=== Network connection after suspend/resume ===
Networking may not work after a suspend or resume operation, this is because of the ath_pci driver and can be worked around by creating the file {{path|/etc/pm/config.d/madwifi}} and adding the single line
<pre>
SUSPEND_MODULES=ath_pci
</pre>
which causes the driver to be unloaded on suspend and reloaded on resume.

=== Fingerprint Reader with ThinkFinger ===
1. Open up your xorg.conf file:
sudo nano /etc/X11/xorg.conf
2. Add to it (or uncomment if it’s already there):
Section “InputDevice”
Identifier “Generic Keyboard”
Driver “kbd”
Option “XkbRules” “xorg”
Option “XkbModel” “pc105″
Option “XkbLayout” “us”
EndSection
3. Under Section “ServerLayout”, add:
InputDevice “Generic Keyboard”

Note: this temporary fix appears to get in the way of Thinkpad keyboard configurations. With the method applied, the up arrow becomes "print screen" and volume buttons stop working.

=== Emulate Wheel (Middle-click scrolling) ===
[http://mvogt.wordpress.com/2008/08/15/xorg-evdev-and-emulatewheel/ Michael Vogt described] how to get middle-click scrolling to work again in Intrepid. Xorg.conf is not used to configure mice and keyboards anymore, but evdev is. This makes the configuration of middle-click scrolling a little bit different than previous versions of Ubuntu. In terminal:
<pre>
sudo gedit /etc/hal/fdi/policy/mouse-wheel.fdi
</pre>
Past and save the following code, which will give vertical wheel emulation only:
<pre>
<match key="info.product" string="TPPS/2 IBM TrackPoint">
<merge key="input.x11_options.EmulateWheel" type="string">true</merge>
<merge key="input.x11_options.EmulateWheelButton" type="string">2</merge>
<merge key="input.x11_options.ZAxsisMapping" type="string">4 5</merge>
<merge key="input.x11_options.Emulate3Buttons" type="string">true</merge>
</match>
</pre>
There is [http://psung.blogspot.com/2008/09/scrolling-with-thinkpads-trackpoint-in.html another method] to get horizontal scrolling as well, but I don't think it worked for me.
