    [SOLVED] Matlab R2011a icon not working in the Unity Launcher (11.04 - 64bit)

    I've just installed MATLAB R2011a (64bit version) in the latest Ubuntu 11.04 (obviously 64bit as well).

    I've followed this http://thameera.wordpress.com/2010/10/21/installing-matlab-2008a-on-ubuntu-10-10/ for the installation part.

    Then after running Matlab for the first time with the command:

    Code:
    sh /usr/local/matlab/bin/matlab
    I right-clicked on the Unity Launcher to add Matlab, but after logging off it disappeared from there.

    Then from Ubuntu help I've tried:

    1. Get an icon:

    Code:
    sudo wget http://upload.wikimedia.org/wikipedia/commons/2/21/Matlab_Logo.png -O /usr/share/icons/matlab.png
    2. Get the launcher file:

    Code:
    sudo wget 'https://help.ubuntu.com/community/MATLAB?action=AttachFile&do=get&target=matlab-r2011a.desktop' -O /usr/share/applications/matlab.desktop
    The icon remains there after closing Matlab, but I've yet to log-off or restart.

    The problem is that when I click on it, it does nothing!

    So to open Matlab I've always to type in terminal:

    Code:
    sh /usr/local/matlab/bin/matlab
    Did any of you succeed in putting a working icon of Matlab in the brand new Unity Launcher?

    Thanks in advance!

    I have the same problem!, on top of that, I feel that it makes my system much less stable.

    I use an extra monitor at work and it gets really unstable when trying to move the Matlab icon on the unity bar and/or simply trying to have it as a permanent icon.

    I had the same problem when using the right click -> keep on launcher option. But then I tried dragging it from the dash to the launcher (before it was running) and it stays there now. Hope this helps.

    The icons stays there, but I can't open Matlab from it!

    Which procedures have you followed to install Matlab?

    Was it working before you moved it to the launcher?

    I should probably have mentioned that I am still using 2010a, I followed these:

    https://help.ubuntu.com/community/MATLAB/R2010a

    But the 2011a ones are here:

    https://help.ubuntu.com/community/MATLAB

    After that I had the error message described and solved here:

    Good luck!

    Re: [SOLVED] Matlab R2011a icon not working in the Unity Launcher (11.04 - 64bit)

    I solved the problem!

    After uninstalling and reinstalling Matlab (useless operation), I logged on Gnome, then after searching for a while I found this 3d: http://ubuntuforums.org/showthread.php?t=1416028

    I followed users' suggestions, then Matlab was working perfectly on Gnome.

    I switched back to Unity, I dropped the Matlab icon from Dash and now works perfectly!

    Thanks again!

    Re: Matlab R2011a icon not working in the Unity Launcher (11.04 - 64bit)

    Hey guys,
    I was having that problem. I'm not very experienced in ubuntu, but I solved like this:
    1- create a launcher on desktop
    2- select run application on terminal
    3- command: sudo /usr/local/MATLAB/R2011A/bin/matlab (change matlab directory to yours)

    after this I placed that launcher on the unity bar. The problem I still couldn't solve is that I can't remove the launcher form the desktop without loosing the one on the unity bar.
    Any thoughts?

    Thanks

    If the issue is removing the launcher form the desktop, just put the launcher (or create a new one and redo the process) in your home folder instead.
    This should be a sticky, or a bug 'cos it ain't a feature
