    Well, depends on what is the "normal desktop environment" you want.

    Ubuntu 11.10 by default only comes with a combination of Gnome 3 and Unity, available in both 3D and 2D variants.

    If you want Gnome Shell instead, you'll have to install it. And same of course goes for any other desktop environment than Gnome.

    If you want Gnome 2, then no, you can't get that any more. It's out of development and unsupported now. Gnome Shell's fallback mode is quite similar, though, as is XFCE4 and perhaps even LXDE.

    Anyway, you of course don't need to install Compiz to change your desktop environment. Not that you even could install Compiz, it's already installed by default like it has been for several Ubuntu versions now. And assuming you were talking about CompizConfig Settings Manager, that's also unrelated to changing your desktop environment. They are simply selected from the login screen..

    Re: Unity Laggy Ubuntu 11.10

    I think we should report this as a bug.
    I see there are different cards involved, OP is ATI, mine is NV.
    I commented on this thread in this one bug:
    https://bugs.launchpad.net/unity/+bug/803943 (Compiz consuming a lot of cpu)

    Re: Unity Laggy Ubuntu 11.10

    I have ATI HD 2600 and it also lagged when I installed Unity.

    I solved it but installing ATI proprietary drivers using "Additional Drivers" program. It seems Unity does not like open source drivers.

    Question Re: Unity Laggy Ubuntu 11.10

    Tried adding more RAM, upgrading to a faster CPU and a better video card, or just using a different DE/WM, like KDE, Openbox, JWM, etc.?

    Re: Unity Laggy Ubuntu 11.10

    Try this simple fix, worked for me (I have the compiz idle effect too, but it's not related to the choppy I think... at least not that much !).

    - Install fglrx driver (stock driver is choppy...)
    - Open AMD Catalyst (after reboot !)
    - Enable "tear free" desktop option
    - Open compiz config
    - OpenGL plugin, untick Sync to VBlank, Texture = BEST, Lighting effect ON
    - Composite plugin, Detect refresh rate unticked, set the refresh rate at double your video frequency (in my case 60 Hz, I set it to 120)
    - Close compiz
    - Log ogg
    - Log in again, it should be now smooth as silk and tear free

    Please give me a feedback on this procedure, as it worked for me since 11.04 till 11.10, seems quite consolidated.

    Be careful not to touch anything else in those OpenGL and Composite plugins !

    Hi guys,
    man, you did it. It really worked. Although it has a little lag, maybe it is because of i am focusing on seeing some lag , but it really has nothing to do to what was before.
    pufff, i couldn't keep seeing this in Ubuntu. Now, lets really try this. I'm so glad.
    Again, sorry about my poor English, but i think i could show how glad i am.

    Hey thank you pal, no worries, I understood perfectly. I spent a looong time over this issue too, pissed me off totally that I couldn't get a smooth Desktop, as utilization of GPU and CPU was practically null and still "choppy".

    Hope this post help everyone with similar problem ! Perhaps we could make an "how to" thread for ATI + fglrx...

    EDIT: when many things are opened, some lag is still normal tough, because anyway the power of the PC is not unlimited.

    Re: Unity Laggy Ubuntu 11.10

    This guid is not very helpful to me with hd2400, but you can try.
    Compiz Config not installed by default, run console and copy this tu install it:

    Code:
    sudo apt-get install compizconfig-settings-manager
    After it you can find compizconfig in main menu by typing "compiz".

    To install ati fglrx driver you can use jockey-gtk.

    Re: Unity Laggy Ubuntu 11.10

    unity is a ram hog i think it uses about 260mb install gnome shell it uses about 140mb ram a bit lighter on the ram its probably laggy cause the update to a newer version has repository clashes.a fresh install is better
