I suggest using the Search function on the forum to look for other people who have posted about FF being slow with scrolling, you will get a lot of hits. You can try some of the methods suggested, hopefully something will work. If not, I don't think you are alone.
    Thanks for the help.. much appreciated.
    Appendix to this... since you know the card Im using (right?) would it be unusual that movements and effects in Hardy are kinda stilted and others are not? Example... jumping between workspaces as a cube is pretty smooth, but moving a window or maximizing or minimizing is again kinda stuttering and slow. I just noticed that scrolling within compiz is even slow.
    Are my settings chosen all ones to really slow things down or what is going on??
    Thanks again!

    Some effects just require more processing power than others. You can try fiddling with settings like going to General Options, Display Settings tab and setting Texture Filter to Fast. I have the 64MB video card size, maybe you have the 32MB, but even mine is a little slow, so I don't actually use Compiz. IMHO, it looks nice, but gets old and I'd rather have a more responsive machine than a flashy one. That's not to say I don't show it off
    You're not the first to complain about some effects being worse than others, it's just the way Compiz is - it really wasn't designed for older machines. Remember, we are using a workaround just to get Compiz to work at all!

    Re: HowTo: Compiz Fusion in Hardy on cards with "ati"/"radeon" open source drivers

    Hi all,

    Having a few issues with this.
    I have a Radeon 9600 and the suggested method works ok but I couldn't enable it without the xserver-xgl drivers installed. So I installed them and now suffering from painfully slow rendering and persistent random hard lockups (no alt-ctrl-backspace or alt-ctl-Fkey)

    After removing xgl and just using the fglrx ati drivers again everything is ok but I'm keen for the effects. Any other options or am I stuck without any chances here?

    thanks
    Aaron

    The Radeon 9600 should be using the restricted fglrx drivers like you said you installed. How did you install them? You might benefit from running the compiz-check script - http://ubuntuforums.org/showthread.php?t=799070

    Re: HowTo: Compiz Fusion in Hardy on cards with "ati"/"radeon" open source drivers

    Thanks Rocket.

    I installed the drivers by:
    Code:
    sudo apt-get install xorg-driver-fglrx
    after enabling the restricted drivers module.

    Compiz-check is what led me to try the xgl driver in the first place but without xgl installed I get 'FAIL' on the first check and fifth check.

    Funnily enough I upgraded to Hardy from Gutsy since posting here (yesterday) and now running compiz-check (without using xgl drivers) yields all 'OK' results:

    Code:
    Gathering information about your system...
    
     Distribution:          Ubuntu 8.04
     Desktop environment:   GNOME
     Graphics chip:         ATI Technologies Inc RV350 AR [Radeon 9600]
     Driver in use:         fglrx
     Rendering method:      AIGLX
    
    Checking if it's possible to run Compiz on your system...
    
     Checking for texture_from_pixmap...               [ OK ]
     Checking for non power of two support...          [ OK ]
     Checking for composite extension...               [ OK ]
     Checking for FBConfig...                          [ OK ]
     Checking for hardware/setup problems...           [ OK ]
    However, I feel there is still something wrong - I am now able to enable the desktop effects without the xgl driver but if I do I am getting some weird misrendered triangles in the corner of my screen randomly upon opening applications and the occasional hard lock when trying to switch between desktops or super-tab between apps. Are there still some settings that I am not getting right?

    This is not a deal-breaker because I love Ubuntu but it'a a bit of an annoyance that I can't get it to work even with a card that should allow me to.

    thanks again
    Aaron

    aaronp, this is not the best place to seek help with your specific video card. This thread is for cards using the open source drivers, but fglrx is the restricted ati drivers. You should start a new thread in this forum so that users more experienced with fglrx can help you out (there should be plenty of them). Good luck.
