Blue Knight Sojourn of the Mind

On my Laptop the Intel Card I have is the Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03). To get this card working with 3D was very simple following the Gentoo Intel How To.

Intel Graphics Card 3D How To

Then just following the How to for the AIGLX you can get the AIGLX working, actually it takes very little work from the how to. You should be able to get it going pretty much by just auto generating the xorg.conf file.

Now getting compiz-fusion going is a bit different, as it required some researching and work. On top of going through the following How To.

Here are the things that I had to do to get it working:

The first thing you want to do is obviously save off a good working xorg.conf as your system may not behave the same way.

The second thing is to modify the xorg.conf and turn on composite to do that either find or create the Extensions section and add the line. Here is my extensions section:

Section “Extensions”
Option “Composite”
EndSection

The next thing you want to do is add the following option to the Device section. I had to get some help on this one as for some reason my system kept locking up after I would turn on compiz-fusion and I was not able to type anything. Here is the line that I was assisted with:

Option “XAANoOffscreenPixmaps” “true”

After this line I was able to get everything working as it should be. So now to find an easy way to get compiz-fusion started. For that you have to look at a package called fusion-icon. But unfortunately it is not in portage so you have to go find it in overlays. Here is a tutorial on overlays for you to reference since I am not going to go in to it here. The overlay you want is called “desktop-effects” and after you get it you can get fusion-icon.

After Fusion-icon is installed just add it to Sessions => Startup Programs. It will start with each X start, and will remember the last settings that you had. So you will be able to set it to you compiz and emarald.

This should work for you. If it does not come to the #gentoo irc channel on freenode and look for me.
