Xgl

FIXME

This article requires a cleanup: reorg, intro, separation of distro-specific info.

Given the overwhelming interest in the two latest eye candy offerings for Linux and their dependence on the underlying hardware, I thought it would make sense to start pages for them. If it needs to be moved, recategorized, or even deleted - have at it.

In the meantime, some links of interest for those wishing to install Xgl:

Freedesktop.org page
OpenSuSE page
Gentoo Xgl HowTo
Ubuntu Xgl HowTo

For those of you on x40's, it apparently is possible to get Xgl running:

Thus far, I've had no success:

How to install XGL on Ubuntu Dapper

The source of this guide is http://ubuntuforums.org/showthread.php?t=145068. Check for updates and update here if neccecery. Original guide by "gandalfn" from ubuntuforums.

1. Add this to your sources.list:

deb http://xgl.compiz.info/ dapper aiglx

deb http://xgl.compiz.info/ dapper main

2. Update your repositories by running:

sudo apt-get update

sudo apt-get dist-upgrade

3. Install latest dri modules packages by running:

sudo apt-get install linux-dri-modules-common linux-dri-modules-`uname -r`

[if after a linux-restricted-modules or linux-image update you have some troubles, run "sudo /sbin/ldm-manager" to regenerate modules.dep]

4. Install Compiz:

compiz aiglx are now partially official, compiz-vanilla packages work now on xorg-aiglx. All compiz-aiglx packages are now deprecated, well first uninstall all compiz-aiglx packages:

sudo aptitude purge compiz-aiglx compiz-aiglx-gnome

sudo apt-get install compiz-vanilla-aiglx compiz-vanilla compiz-vanilla-gnome

5. Configure Xorg:

update /etc/X11/xorg.conf with:

Section "Module"

6. Create or modify /etc/gdm/gdm.conf-custom to change your xorg server like this:

[servers]
0=aiglx
[server-aiglx]
name=aiglx server
command=/usr/bin/Xorg-air :0
flexible=true

7. Restart GDM:

sudo /etc/init.d/gdm restart

and choose XGL from the session menu :)
