    Just follow the link to another forum post that I had in my initial posting that started this thread. It is possible to reduce the icon size for unity 2d - it requires you to use your editor to make manual changes to certain config files.

    And for the "real unity" thing: problem solved. As others probably expected: user error.
    Here is what happened:

    I am using virtual box to run my 12.04 LTS. I reused an existing virtual machine; but I
    did create a new disk and installed the 12.04 final ISO in that virtual machine.
    Thing is: I assumed that I had "3d support" enabled; but I just figured that this
    was not the case.

    Long story short: I was running unity-2d all the time. I realized that by
    entering

    > ps -ef | grep unity

    on the command line.

    So, I stopped the VM; enabled 3d support; eh voila, I log in using "real unity";
    and there is the slider on the appearance panel.

    The only thing could be done better on the ubuntu side: I manually
    selected "ubuntu" (instead of ubuntu 2d) on the login page ... but
    there was NO indication that my selection wouldnt work out.

    So I told ubunut: "log in using real unity"; and I was never told
    that I actually logged in using unity-2d.

    I had an issue with the Unity 3D when I UPGRADED from 11.10 and the 2D wouldn't work and the 3D worked but no slider and there utilities for changing the config of Unity 3D didn't work neither which lead me to perform a full clean installation.

    If you have upgraded then the config's and application settings are kept from your previous version and 12.04 will boot into Unity 2d as default, due to an error with the upgrade sequence for booting into Unity 3D. Some systems which I've upgraded (there being 28 systems) only 6 or 7 of them actually upgraded perfectly and booted into unity 3D and had the slider at the bottom, the others I had to backup and and perform a clean installation.

    Hope some of it explains why...

    Thanks

    Thanks for this thread. I, too, have been trying to change the Icon size. I logged out and made certain I picked "Ubuntu" instead of "Ubuntu 2D" and still no icon changer at the bottom of the control window. Any other thoughts? I am using 12.04LTS. Has the function been completed disabled in that version? Do I need to download a new Unity? Thanks for any help. Not a big deal, but my glasses still work well enough to make the icons smaller.

    If your graphics card/driver combination is not enough to run Unity 3d, even if you choose Ubuntu at the log in screen, it will still default to Unity 2d. It sounds as though you are running Unity 2d, but there's another way to check. Is there a drop shadow under the menu bar (bar at top)? If yes, you are running Unity 3d. If no, Unity 2d.

    Also. From a terminal:

    Code:
    /usr/lib/nux/unity_support_test -p
    That will tell you if your graphics card can support Unity 3d. If you need any help, post the output of that and also the output of:

    Code:
    lspci | grep VGA
    The second command reveals what your graphics chipset is.

    Thanks CoffeeCat. No drop shadow, so I am running Unity 2D.


    Here is the first output:

    OpenGL vendor string: Tungsten Graphics, Inc
    OpenGL renderer string: Mesa DRI Intel(R) 865G x86/MMX/SSE2
    OpenGL version string: 1.3 Mesa 8.0.2

    Not software rendered: yes
    Not blacklisted: yes
    GLX fbconfig: yes
    GLX texture from pixmap: yes
    GL npot or rect textures: yes
    GL vertex program: yes
    GL fragment program: no
    GL vertex buffer object: yes
    GL framebuffer object: yes
    GL version is 1.4+: no

    Unity 3D supported: no

    I guess the last line tells the tale.


    This is the second ouput:

    00:02.0 VGA compatible controller: Intel Corporation 82865G Integrated Graphics Controller (rev 02)


    Does that tell you anything else? I am using the graphics integrated into the motherboard.

    I MIGHT have an old AGP graphics card around here somewhere. Would that possibly help? Probably not a whole lot of RAM on it.

    Thanks, again. This is, and always has been, a great forum.

    Re: 12.04 - changing unity launcher icon size ...

    The Intel 865G video is very legacy - I doubt there's a way you'll ever get good enough performance out of that for Unity 3d. If you do find an old AGP card, it *might* help. The trouble is AGP is a legacy standard and any GPUs that come with AGP cards are going to be old ones. You might be lucky. If you find it, plug it in and boot up. Ubuntu will autodetect it and apply the appropriate driver. Then try the first command. If you need help post the outputs of both commands with the AGP card working.

    Good luck!

    Re: 12.04 - changing unity launcher icon size ...

    I'm not seeing any slider for the icon size in the launcher either. My video card is a three year old NVidia GeForce 9800GT. When I run the unity support test referred to earlier, it tells me Unity 3D is not supported. I thought this might have something to do with the video driver. So I opened up "System Settings" and double clicked "additional drivers". Several 3D drivers were listed, including a recommended one. I selected it, activated it, and restarted. I wound up with a screen with no launcher. I tried most of the other drivers, but same story. No launcher. I finally reverted back to the default (2D driver).

    I wonder if any settings in my BIOS could be causing the failure of the driver. Anyone have any ideas about this?

    Re: 12.04 - changing unity launcher icon size ...

    I have a similar problem. My trouble is this. I have Ubuntu 11.10 installed on my desktop and laptop (from the same ISO image/install CD disk) and recently both have been upgraded to 12.04 via the link in the Update Manager. Then, both 12.04 installs have been updated with all system updates. On the laptop. the Launcher Size slider does show up at the bottum in the Appearence window; but this is not true in the desktop Ubuntu 12.04. I am wondering why.

    Reading through the forum, some said that the Launcher Size sliding scale is not in the Unity2D. But how do I know which Unity version is installed?
