    11.10 missing top and side panels

    I upgraded to 11.10 from 11.04. After update everything to do with graphics eye-candy (Unity side panel, alt+tab window switching, window dragging etc) was lagging and slow. Also touchpad wasn't working (trackpad was though, I'm using a Thinkpad T60 with ATI x1400 graphics).

    Then I decided to install CompizConfig Settings Manager. After running it, HDD was thrashed for a few minutes, system was unresponsive and when it restored my top and side unity panels disappeared.

    Now I can have the top and side panels only when logging in with the "Ubuntu 2D" mode. When I log in with the "Ubuntu" mode, there are no panels.

    Don't know what to do right now, couldn't find any solutions.

    "unity --reset" gives me
    warning: no Display variable set, setting it to 0
    unity-panel-service: no process found

    re-open ccsm & make sure the unity plugin is enabled - it can be unset from certain actions in ccsm

    Re: 11.10 missing top and side panels

    Try to run this on console:

    Code:
    DISPLAY=:0.0 /usr/lib/nux/unity_support_test -p
    It will tell you if your system supports Unity 3d. If it says you don't, mist likely you don't have proper video drivers installed. Try to follow the procedures I described here (post #5 and on):

    Re: 11.10 missing top and side panels

    well i did foresee that upgrading would be problematic or break a functional desktop for many...

    anyway, does unity 3d works correctly from a live-cd or usb?

    and/or run the test as described above

    Re: 11.10 missing top and side panels

    Unity 3D worked in 11.04 and until I ran CompizConfig Settings Manager it worked in 11.10 aswell, although it was lagging the way it never had before in previous Ubuntu versions.

    Code:
    DISPLAY=:0.0 /usr/lib/nux/unity_support_test -p
    OpenGL vendor string:   X.Org R300 Project
    OpenGL renderer string: Gallium 0.4 on ATI RV515
    OpenGL version string:  2.1 Mesa 7.11
    
    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:      yes
    GL vertex buffer object:  yes
    GL framebuffer object:    yes
    GL version is 1.4+:       yes
    
    Unity 3D supported:       yes
    But I can't follow effenberg0x0's instructions, because ATI dropped releasing proprietary drivers for x1400 since Catalyst 10.2. Which I allready tried to install and resulted in:
    Code:
    Error: ./default_policy.sh does not support version
    default:v2:i686:lib::none:3.0.0-12-generic:; make sure that the version is being
    correctly set by --iscurrentdistro

    Re: 11.10 missing top and side panels

    Unity test already reported your card is supported, although is using the galium.
    I imagine you can use the 2D session normally. Inside this session, open a terminal and run:

    Code:
    unity --reset
    sudo service lightdm restart

    If you again get to a session with no launcher or panel, press Ctrl+alt+F1 to F6 to go to a VT. Login at the VT and run

    Code:
    DISPLAY=:0.0 /usr/bin/ccsm
    Switch back to the desktop with Ctrl+Alt+F7. YOu'll see ccsm there. Make sure the Ubuntu Unity Plugin is activated, as swell as OpenGL and Composite. If not activate it.

    Switch back to the VT and run:
    Code:
    sudo service lightdm restart
    Make sure you're selecting Ubuntu this time, enter your password, login.

    Report back

    Re: 11.10 missing top and side panels

    Code:
    unity --reset
    Is giving me problems:
    Code:
    WARNING: no DISPLAY variable set, setting it to :0
    unity-panel-service: no process found
    and just stays there. When I ctrl+c it and continue with:
    Code:
    sudo service lightdm restart
    Then when I log in with "Ubuntu", I don't have the panels. The next step gives me:
    Code:
    DISPLAY=:0.0 /usr/bin/ccsm

    Had to cancel that with ctrl+c aswell, because it hanged there. When I have checked that those things are enabled in CCSM and continue with restarting lightdm and login using "Ubuntu", then nothing has changed.

    Re: 11.10 missing top and side panels

    You have to have a Graphic Session running in order to reset unity. So try to login again. Click the gear and make sure Ubuntu is selected, not Ubuntu 2d. If you get again to a session with no launcher / panel, you can switch to another VT (Ctrl+Alt+F1 to F6), login, and run it like this:

    Code:
    DISPLAY=:0.0 unity --reset
    Then you'll run ccsm like this now:

    Code:
    DISPLAY=:0.0 /usr/bin/ccsm &
    See, there's an ampersand in the end.

    And you will press Ctrl+Alt+F7 to get back to the desktop. Then you'll see CCSM there and check if the Ubuntu Unity Plugin is activated, maybe deactivate/reactivate it, etc.

    Once you're done, switch back to the VT (Ctrl+Alt+F1 to F6) you were and run

    Code:
    sudo service lightdm restart

    Re: 11.10 missing top and side panels

    Should these commands be able to end themselves or do I have to force close them?
    Code:
    DISPLAY=:0.0 unity --reset
    DISPLAY=:0.0 /usr/bin/ccsm &
    Because they seem to get stuck.

    I've tried this several times now, but it haven't had any luck getting it to work yet.
