Configuration Details

• CPU: AMD Sempron 3000+ (1.8GHz)
• RAM: 768MB (128MB dedicated to graphics)
• Motherboard: Unknown/Generic
• Video: ATI Xpress 200M built-in (RS480) (DX9/OGL2 class)
• Audio: ATI Xpress 200M built-in (AC97)

• WiFi: Broadcomm 4318 type (using WindowsXP drivers from HP site in ndiswrapper). Using bcm43xx driver in Dapper.

Current Issues

• There is a bug/error in hotplug that make it load the hda-intel module first which makes the system stuck in a loop. Dapper's udev loads the module, but it doesn't cause problems, I blacklisted it anyway.
• X uses the ati module by default which causes problems for X (use vesa)
• The touchpad has a horizontal scroll area which isn't autodetected. (No biggie.)

Hardware details

Notes

1. This info will be updated as I test things.

Hotplug and a problem

• Sound works properly after doing proper configuration
• Hotplug loads the hda-intel module which tries to scan for the Intel HD chipset and doesn't find it. This causes the hotplug system to get stuck in a loop which is not infinite but never ends. (The condition never gets satisfied).
• The reason why this happens is believed to be because of PCI ID issues. Hotplug might not realise what sound card it is and try every module that it has access to.
• Dapper's udev loads the module but it actually gets loaded without trouble, along with the correct module

Fixing the Hotplug problem

• You need to have a LiveCD Linux distribution ready before installing. I used Knoppix LiveDVD 4.0.2.
• After installing and having the system get stuck on "Starting hotplug subsystem..." shut the system down and boot into Knoppix from the DVD (or CD).

• You need to mount the hard drive then edit the /etc/hotplug/blacklist file.

• At the end of the file add the following:

  snd-hda-intel

• Reboot the system after saving the file and not forgetting to take the Knoppix DVD (CD) out.
• Everything should load from the hard disk and continue installing Ubuntu. But there will be another problem.

Fixing Xorg

• Xorg detects the ati card and loads the ati module. Which would be fine if the ati module supported the Xpress 200M (RS480) chipset.
• Since Gnome will not load, you still have the command line interface.
• You will have to edit the Xorg configuration file to use the vesa module (it provides basic display support).

• Use the following command to open the file in nano:

  sudo nano /etc/X11/Xorg.conf

• Find the line which looks like this:

  Driver "ati"

• Change the ati part to vesa. The edited line should look like this:

  Driver "vesa"

• Save the changes and exit.

• Reboot the system and GMD should get loaded and after logging in, you should see the gnome desktop.

• To get the 3D accelaration to work, follow the guide here: https://wiki.ubuntu.com/BinaryDriverHowto/ATI

Lid close

• After opening the lid, a promt for password appears, looks like a mini login type thing. This is standard I believe.

About the touchpad

• X finds it, configures it and it works.
• Vertical scrolling also works.

• Horizontal scrolling doesn't work, although I think that it can be easily fixed through QSynaptics (http://qsynaptics.sourceforge.net/)

Wifi button

The button seems to affect the hardware side of the wifi card. if the light is lit, then the wifi card is actually physically on. In connection manager, if it is disabled, then ubuntu won't be able to connect with it. In Dapper, the button has zero effect. Unloading the modules makes the card go off.

Media Buttons

• If you press play without Totem being on, it will run Totem (by default)
• Stop doesn't work because Totem doesn't have a "stop" function. Haven't tried other media players.

Hibernate

When I set the laptop to hibernate from shutdown menu, it shuts down, but when I power it back on it gives errors about IRQ and does not boot.
