Ubuntu Unleashed

Keep up the good work man !

I have a much older - Radeon 9250 and it works fine for me after some tweaking (and without skipping the checks):

1. first of all install some extra packages (if not already installed):

sudo apt-get install libgl1-mesa-glx libgl1-mesa-dri

2. Edit /etc/X11/xorg.conf. It should have the following additions:

Section "Device"

Identifier "ATI Radeon 9250"

Driver "ati"

## For Compiz - start

Option "AGPMode" "8"

Option "AccelMethod" "XAA"

Option "ColorTiling" "on"

Option "EnablePageFlip" "true"

Option "GARTSize" "64"

Option "XAANoOffscreenPixmaps" "true"

## For Compiz - end

BusID "PCI:1:0:0"

EndSection

Section "Monitor"

Identifier "AOC"

Option "DPMS"

## For skype 2.0 video - start

Option "OpenGLOverlay" "off"

Option "TexturedVideo" "on"

## For skype 2.0 video - end

EndSection

Section "ServerLayout"

Identifier "Default Layout"

Screen "Default Screen"

## For Compiz - start

Option "AIGLX" "true"

## For Compiz - end

EndSection

## All of these sections were added for Compiz

Section "DRI"

Mode 0666

EndSection

Section "Extensions"

Option "Composite" "Enable"

EndSection

3. Restart X server, and execute:

compiz --replace

or just enable special effects in GNOME / KDE

viola ! Cool effects at full capabilities. even with an ancient card like mine...

NOTE: the option "GARTSize" has caused me problems before. You may need disable it if X server hangs.

NOTE2: The addtion for Skype 2 - the video works fine but first you have to disable Compiz (sadly they will not work together)

Does this work if the resolution is above 1024x768? My Latitude D600 runs natively at 1400x1050, and the entire screen to the right of pixel column 1024 is totally unusable; Compiz whites out that chunk of the screen, and anything placed in that area is cut off. I remember reading some time back that outside of FGLRX or nVidia, there was a hard texture limit of 1024 horizontal...

I had exactly the same problem re the display whiting out the right side of the screen. However by using xserver-xorg-video-ati driver (I swapped the driver from fglrx to the xorg simply by uninstalling fglrx as I installed the xorg driver using synaptic) and the following bits of my xorg.conf I was able to get compiz up and running. I hope it helps.

Hi. I see you found my forums post, but shortly after I posted it I updated it (and a few times since then as well). It is not really safe to add the SKIP_CHECKS to /usr/bin/compiz so there is a safer workaround provided. You should update your blog entry here.
