Wireless LAN LED not functional by default under 6.10 (Edgy), 6.06 LTS (Dapper) or anything prior

Apparently the Wireless LAN LED functionality sometimes causes lock-ups / freezes - I've never experienced this

To enable this, add the module options for the ipw2200 driver as follows: 

sudo nano /etc/modprobe.d/ipw2200

Add this line, then Ctrl-O and Ctrl-X to save and exit: 

options ipw2200 led=1

Unload and reload the module as follows: 

sudo modprobe -r ipw2200
sudo modprobe ipw2200

Touchpad does not work correctly under 6.10 (Edgy)

Open a Terminal. Applications -> Accessories -> Terminal

Backup xorg.conf first 

sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.orig

Edit /etc/X11/xorg.conf 

gksudo gedit /etc/X11/xorg.conf

and put this info in 

Section "InputDevice"
 Identifier "Synaptics Touchpad"
 Driver "synaptics"
 Option "SendCoreEvents" "true"
 Option "Device" "/dev/psaux"
 Option "Protocol" "auto-dev"
 Option "HorizScrollDelta" "0"
EndSection

and insert the following line into the ""ServerLayout"" section 

InputDevice "Synaptics Touchpad"

Now save the file, and then in terminal run: 

sudo dpkg-reconfigure -phigh xserver-xorg

Display does not use correct resolution in neither Ubuntu 6.10, 6.06 LTS nor 5.10

From terminal run: 

sudo apt-get install 915resolution

Then restart x.org server 

Ctrl + Alt + Backspace

For more info refer to this page i915Driver

Notes on Ubuntu 6.06 LTS Installation

  • Touchpad scroll button: Initially doesn't work - Need to run sudo dpkg-reconfigure xorg-xserver

  • Correct resolution: 1280x800 requires you to run sudo apt-get install 915resolution

  • As with 6.10 - Wireless LED not active by default (See Notes to enable)

Notes on Ubuntu 5.10 Installation

Notes on Ubuntu 5.10 to 6.06 LTS Upgrade

  • Hibernate issues in Breezy resolved in Dapper
  • Battery Detection issues in Breezy resolved in Dapper
  • Sound issues in Breezy resolved in Dapper

Notes on Ubuntu 6.06 LTS to 6.10 Upgrade

  • After kernel upgrade PCI cannot allocate resource region 7, 8 and 9 - Bug#56376 (No known effect)

  • Although opengl shows 3D rendering active, performance on 3D not equal to OS's with binary drivers (i.e. MS-Windows and SUSE Linux)
