Introduction
This page explains how to enable Accelerated Indirect Rendering on your Ubuntu Edgy system.
For more information, including a list of supported hardware, please see the UbuntuHelp:CompositeManager/AIGLX page.
Enabling AIGLX
1) Configure the X server
Open up /etc/X11/xorg.conf
in a text editor as root by going to Applications > Accessories > Terminal
, typing the following command and pressing enter.
gksu gedit /etc/X11/xorg.conf
Under Section "Module"
, make sure that the following lines are included:
Load "dri" Load "dbe" Load "glx"
Next, find the Section "Device"
for your graphics card, and add the following:
Option "XAANoOffscreenPixmaps" "true"
And finally, add the following to the bottom of the file, unless it already exists elsewhere:
Section "DRI" Mode 0666 EndSection Section "Extensions" Option "Composite" "Enable" EndSection Section "ServerLayout" Option "AIGLX" "true" EndSection
NVidia users will need the following to their Section "Screen":
Option "AddARGBGLXVisuals" "True"
2) Restart the X server
Ubuntu users:
sudo /etc/init.d/gdm restart
Kubuntu users:
sudo /etc/init.d/kdm restart
Troubleshooting
An excellent guide for properly editing your xorg.conf file can be found here:
It is important to follow all the steps, especially if you are having problems using Compiz/Beryl and the windows decorator (i.e. the title bar with the minimise, maximise, close buttons) is missing!
