How do I create a hardware profile in Ubuntu 8?

[Martje_001]

You could try this (I don't guarantee it's going to work!):

gksudo /etc/X11/xorg.conf

and then change these lines:

        Option  "AIGLX" "off"
        Option  "Composite" "Disable"

to:

        Option  "AIGLX" "on"
        Option  "Composite" "Enable"

Before you do that, make a backup by entering these commands:

sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.bk

Then restart your computer (or press CTRL + ALT + BACKSPACE, but that's not recommended).

If you're able to start up, test if compiz-fusion works or not by entering this command:

compiz --replace

If you're unable to start up (i.e. get the GUI running) press CTRL + ALT + F1, login, and enter this command:

sudo cp /etc/X11/xorg.conf.bk /etc/X11/xorg.conf

Now, restart your computer again and everything is back to normal.

Since your last message I bought an Nvidia video card and installed it.

I still can't get the 3D cube to work though.
I entered the code you suggested and this is the message I received.

Checking for Xgl: not present. 
Detected PCI ID for VGA: 01:00.0 0300: 10de:0326 (rev a1) (prog-if 00 [VGA controller])

Checking for non power of two support: present. 
Checking for Composite extension: not present.

I meant to say, I entered the last code you suggested

What have you done to get compiz working so far?

[Vistawho?]

Well, I've done a couple of things.
Mainly I followed these instructions found here:

I still haven't been able to see any 3D graphics but it has helped a lot.

I think that when I installed the Nvidia card, it automatically found the drivers for it and removed others that I am not using. I tried

gksudo /etc/X11/xorg.conf

and it returned nothing.
I think I saw something to do with xorg being removed at the time.
I really appreciate your help on this.
I am also searching the forum for any possible solutions to getting the 3D stuff up and running.
I hope I don't mess anything up

Hi Nothingspecial.
I thought I would add the fact that when I go to "System - Preferences - Appearance - Visual Effects" I get an error message "The composite Extension is not available" when I click on either "Normal" or "Extra"
Does this mean I need to install or activate something else?

Cheers

So, now you have a Nvidia card? Good!

Install envyng and envyng-gtk and start Envyng (it's in your menu) and install the drivers for your videocard. Good luck!

Hi Martje_001.

Did as you said. Worked a treat! Now I will play with this for a while and see what it can do.
Is this what I needed to get the 3D cube working?

Thanks heaps

You need to check the custom box in system > preferences > appearance > visual effects.
