Compiz on Ubuntu - tutorial

Seperti yang dijanjikan, tutorial untuk install compiz on ubuntu.
** Tutorial taken form - http://www.tectonic.co.za/wordpress/?p=916 ** so.. credits goes to them, not me~!!!

Step one
Let’s add dapper sources to apt. If you are one of the lucky ones already running it, skip to the next step. Otherwise, just throw this line in /etc/apt/sources.list/: deb http://archive.ubuntu.com/ubuntu/ dapper main universe restricted multiverse apt-get update, apt-get dist-upgrade, and you’re good to go. As has been mentioned in some feedback, this can take a long time, especially for those without very fast connections. However, I would recommend it for this tutorial. My main man Exdaix reports that trying to pull down the Compiz package on Breezy ended up pulling down a lot of Dapper packages anyway… so be cool like him, and dist-upgrade.

Step two
Let’s pull down some new stuff. Since around 15 February, everything you need should be in two packages. Ubuntu has now split the Compiz window manager components into separate packages. Depending on your desktop environment, add compiz-gnome or compiz-kde to this list. Open a terminal, and: apt-get install xserver-xgl compiz (compiz-gnome or compiz-kde here) Okay! Compiz and everything we need is installed.

Step three
Now, everything we need is ready. We just have to invoke it. My technique of preference is to stick everything in userspace scripts, rather than create symlinks or modify gdm.conf-custom. I do this because (like before) I’m lazy, and would rather not make system-wide changes if I don’t have to. So, open your favourite text editor. Throw this little passage in ~/.Xsession (and create if necessary): (Credit for the original version of this script goes to http://doc.gwos.org/index.php/Installxgl.) Note: I have an ATI card. If you are using Nvidia, try replacing Xgl :1 -fullscreen -ac -accel xv -accel glx:pbuffer & with Xgl :1 -fullscreen -ac -accel xv:fdo -accel glx:pbuffer &. If you want to run KDE, try replacing gnome-window-decorator with kde-window-decorator, and exec gnome-session with exec startkde.

#!/bin/sh
# Start up Xgl, compiz, and GNOME
# Run Xgl server on :1, on top of normal X
Xgl :1 -fullscreen -ac -accel xv -accel glx:pbuffer &
# Tell subsequent X programs to access the Xgl server at :1
DISPLAY=:1
# Start Compiz window manager
gnome-window-decorator &
compiz gconf decoration wobbly fade minimize cube rotate zoom scale move resize place menu switcher &
# Start GNOME
exec gnome-session

Now make sure it’s +x’d/executable with chmod +x ~/.Xsession. We have now set up your user X session to start the Xgl acceleration on top of regular X, initialize Compiz, and then start Gnome in the new GL-groovified layer. Do note that since Gnome is running on top of our Xgl layer, Gnome and your desktop applications will be running on the Xgl display :1 instead of the usual :0. Try ‘Er Out!
Let’s see if what we did worked. Now cross your fingers, clamp your eyes shut, and reverently whisper “gui acceleration.” Yes, you’ll have to close this Howto. Try to hold back the tears, however hard that may be. Here’s what we’ll do. In just a moment, log out of Gnome. Then open that menu at the bottom left and change the session: make sure you’ve selected the default session setting, so that our .Xsession file is run. But wait, where’s my fallback plan? What if things go wrong? If anything breaks or starts acting scary, just close down, reboot, or somehow intervene. If you wish to undo, simply go back to GDM and change the session to “Failsafe Gnome.” The .Xsession file responsible for initializing the Xgl layer should not run, and you can delete it in the comfort of your gui environment. In the worst case, you can log into single user mode from grub and delete the file there. I include this because I know it’s no fun to be left with a non-functioning X configuration without knowing how to undo it - only because I’ve been there so many times. This is not rocket science, but it *should not* torch your system. However, know that there are lots of options. If things work, you’ll see a checkerboard pattern come up on login, followed by a blue background. The Gnome splash screen will then fade and wobble in with the most rockin’ graphics you’ve ever seen. Come right back here and I’ll show you what you can do with your new bling machine. Now, go do it! May the geforce be with you, and all that.
