If you are like me, you probably like to have some eye candy and the Luminocity demos enticed you. All those effect look great, but what good are they if we have to wait years for the effect to get into Gnome?

I created this howto to help people like myself install Luminocity now in order to try out the new effects. It does alright on my Pentium 4 with an ATI card (newest fglrx drivers installed), but using a mouse wheel seems to make it crash (anyone got a work around?).

This is fun to play with (I really like the desktop switcher) but its not a functional window manager like Metacity. Its only to be looked at. So don't show this off to all your Window's buddies (unless you say "this is the future of Linux") because they will be disappointed when they switch to use it only to find out its basically a demo.

This howto was created by adding this Gentoo one to this wikipage:

For future note, every time you see bold, it is a new command line to enter.I will only use the bold for bash commands.

First we need to install some things.

'''apt-get install cvs libtool libxxf86vm-dev build-essential docbook-xsl automake1.7 libglib2.0-dev libgtk2.0-dev xlibmesa-glu-dev '''

Now lets make a directory:

'''mkdir luminocity'''
'''cd luminocity/ '''

Now we need to install jhbuild:

'''cvs -d get jhbuild'''
'''cd jhbuild/'''
'''make install'''

I don't really get this part but its needed to work:

'''cvs -d get '''
'''cp luminocity/luminocity.modules modulesets/'''

Now get out of that directory

'''cd ..'''

and start gedit:


Add the following quoted text to the new gedit file. Be sure to change where it says "username" to your username.

"import os

moduleset = 'luminocity'
modules= [ 'luminocity' ]

cvsroot = ''
checkoutroot = '/home/username/luminocity/src/luminocity/'
prefix = '/home/username/luminocity/opt/luminocity'
autogenargs='--enable-maintainer-mode --disable-static'

os.environ['INSTALL'] = os.path.join(os.environ['HOME'], 'bin', 'install-check')"

Save the file as "jhbuildrc-luminocity"

Now to make more directories

'''mkdir ~/luminocity/src/'''
'''mkdir ~/luminocity/opt/'''

And tell your computer to use the older version of automake (the 1.9 version won't work apparently).

'''export AUTOMAKE=automake-1.7'''
'''export ACLOCAL=aclocal-1.7'''

Now its time to install Luminocity.

'''~/bin/jhbuild -f ~/luminocity/jhbuildrc-luminocity build xserver luminocity'''

Hit enter when it asks for a CVS password.

You are now building Luminocity. It took 30 minutes on my Pentium 4.

If you have no error, Luminocity is installed. Time to use it. First enter this command (this must be done everytime):

'''~/bin/jhbuild -f ~/luminocity/jhbuildrc-luminocity shell'''

Now its time for the xfake line. I will take this and its explination straight from the Gentoo guide:

"If you want to change the window size, start Xfake with:Xfake -screen <width>x<height*number_of_workspaces>x<bpp>
It's also a good thing to add "-nolisten tcp" to Xfake arguments to improve safety.

For example, this would make luminocity to open in 1024x768 window when using 4 workspaces:"

'''Xfake -ac -nolisten tcp -screen 1024x3072x32 :1 &'''

Then you need to say what windows to stick in Luminocity using a command. This example is for Gxine:

'''DISPLAY=:1 gxine &'''

Now its time to start Luminosity:

'''luminocity :1'''

Here is the explanation for that command from the Gentoo forum:

"You can change the number of workspaces by starting luminocity with "-d <number_of_workspaces>" argument.
It's also possible to add background image to luminocity by simply adding background path after luminocity start command:"

'''luminocity :1 -d 4 /path/to/background '''

Well...thats about it. I hope you enjoy it.I can't wait till this stuff is actually part of Gnome. I'm estimating two more releases before that happens...but that is probably optimistic. I'm glad we can try it out today! Viva la OSS!

In terms of usability, it's a tad unresponsive on my Radeon 9200SE and only marginally less so than it was on my Radeon Mobility 9000. For some reason using my scrollwheel crashes the whole shebang. Other than that it's sweet and as a sign of things to come it's fantastic.
