You can run "glxinfo" or "glxgears" to see if you're getting accelerated graphics or not.

It may be that the Ubuntu packages do everything but update your xorg.conf file too.

The specific packages (assuming a standard kernel system) you'll need are:

linux-restricted-modules-2.6.10-5-386 (2.6.10.4-1) [restricted]
xorg-driver-fglrx (6.8.0-8.8.25-0ubuntu10) [restricted]
xorg-driver-fglrx-dev (6.8.0-8.8.25-0ubuntu10) [restricted]

Linux restricted modules contains the kernel module fglrx needs in addition to the XOrg driver.

Check out your xorg.conf file:

sudo gedit /etc/X11/xorg.conf

Under Section "Device", look for a saying something like: Driver "ati" and change "ati" to "fglrx". You may also need to add

Option "UseInternalAGPGART" "no"

before the EndSection for Section "Device". It should look something like this:

Section "Device"
Identifier "ATI Technologies, Inc. Radeon Mobility 9600/9700 M10/M11 (RV350 NP)"
Driver "fglrx"
BusID "PCI:1:0:0"
Option "UseInternalAGPGART" "no"
EndSection

Reboot or log out and kill X and you should be using accelerated ATI drivers.
