Solutions

ATI Mobility Radeon X1400 (128 MB)

To get hardware acceleration and a resolution >1024x768, you need to install ATI's fglrx driver.

1. Install the fglrx driver:

$ sudo apt-get install xorg-driver-fglrx

2. In Edgy the Composite extension is enabled by default, however, fglrx does not yet support Composite with DRI. In order to disable Composite you have to edit the xorg.conf file:

$ sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.backup

$ sudo gedit /etc/X11/xorg.conf

3. Add these lines at the end of the file: 

Section "Extensions"
	Option	    "Composite" "Disable"
EndSection

4. Now activate the fglrx driver:

$ sudo aticonfig --initial

$ sudo aticonfig --overlay-type=Xv

5. After restarting your system (or alternatively doing CtrlAltBackspace to restart the X Server) your system will be running the fglrx drivers.

Intel PRO/Wireless 3945ABG Mini-PCI Express Adapter

Getting WPA working with your Wifi card is easy.

1. Install the network-manager-gnome package

$ sudo apt-get install network-manager-gnome

2. You have to deactivate the GNOME network settings for all networking devices that should be controlled by network-manager: 

System -> Administration -> Network

3. In the network settings deactivate the Wifi network.

4. Log out and log in again to activate the new settings.

IrDA 1.1 (FIR - 4Mbps)

IrDA does not work out-of-the-box because the necessary package and configuration is not included in a stock Ubuntu install.

1. Install the missing package $ sudo apt-get install irda-utils

2. Configure irda-utils

$ sudo dpkg-reconfigure irda-utils

3. On the configure screen set the options as the following: 

Activate IrDa on boot-up: yes
Attempt to probe for IrDa at system boot: yes
Discovery mode: yes
Typ of the IrDa-adaptor: native
Typ of the FIR-chip: nsc-ircc
Options for the modules of the FIR-chip:
Port for setserial to deactivate:

4. Restart IrDA:

$ sudo /etc/init.d/irda-utils stop

$ sudo /etc/init.d/irda-utils start

5. Load the FIR IrDA driver:

$ sudo modprobe irda0

6. Now test if activating IrDA was successful. Place your IrDA device (mobile phone, PDA or whatever) in front of the IrDA eye and activate IrDA on your device. Doing a

$ cat /proc/net/irda/discovery

should list your IrDA device.

4-in-1 digital media reader (MultiMedia Card, MemoryStick, SD)

The digital media reader does not work because the kernel module tifm_sd is not loaded on startup. To get it loaded, add it to the modules file:

1. Open the file modules (and do a backup first, just in case):

$ sudo cp /etc/modules /etc/modules.backup

$ sudo gedit /etc/modules

2. Add the following to the end of the file: 

tifm_sd

3. Save the file and restart.
