I realize that Webex does not support Ubuntu 11, however I have a website running on my machine that I need to demo for a client and he will use webex. I need to be able to use the "share desktop" feature to do this. Is there any dependable way (gksudo, java installation, browser, anything) that lets you share your desktop?

I don't care if the audio crashes since we talk on the phone, and it's okay if it cuts out from time to time -- I just need him to be able to see it.

Alternatively, is there an easy way for me to switch to an ubuntu version that will allow me to share my desktop?

You could try ScreenLeap, which seems to have a very low setup overhead (it just downloads and runs a Java applet).

After much trial and error, I was able to get WebEx desktop sharing working in 64-bit Ubuntu just by installing a few packages (confirmed working on 14.04 and 12.04):

  1. Install 32-bit Java, a necessary 32-bit library, the Java plugin, and Firefox:

    sudo apt-get -y install openjdk-7-jre:i386 libxmu6:i386 icedtea-7-plugin firefox
    
  2. Make sure the correct Java plugin is configured:

    sudo update-alternatives --auto mozilla-javaplugin.so
    

    If for some reason that doesn't do the trick, you can try this instead:

    sudo update-alternatives --set mozilla-javaplugin.so /usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/IcedTeaPlugin.so
    

Close and re-open Firefox, and WebEx desktop sharing should work.

  • You must use Firefox. WebEx will not work on Google Chrome as Chrome for Linux no longer works with Java.
  • If you don't install the exact packages listed above in step 1, WebEx will work, but desktop sharing will not work.

I had webex working on 12.04, but now I switched to 14.04 I get it to almost work. Everything except the actual screen sharing works. So I go into the meeting and see the other people, but I an unable to see the shared stream. –  balachmar Apr 4 at 14:26
    
If I get a chance I'll test on 14.04, but in the meantime I blogged about some other methods that may work if the above doesn't: Using WebEx desktop sharing on Ubuntu 64-bit –  bmaupin Apr 4 at 15:36
    
I have the exact same problem. Working fine with 14.04 but I can't see what other people is sharing. –  jmend Aug 27 at 18:02
    
@balachmar I just tested these same exact steps on Ubuntu 14.04, and they worked fine. It's very important you install the exact packages as listed. I tried with many other combinations, and none of them worked. If you don't have the exact packages installed, WebEx will work but desktop sharing will not work. –  bmaupin Sep 5 at 14:33
    
@jmend I have to create a separate comment so you get notified (meta.stackexchange.com/a/45296/206677), but read my previous comment –  bmaupin Sep 5 at 14:34

So I've struggled with this for years, and finally have a solution.

  1. Install Ubuntu 32-bit. 64-bit simply won't work with Cisco's Webex Java plugin. I fought this for years, and finally gave up. I installed Ubuntu into a VM using [testdrive][1].
  2. sudo apt-get install icedtea-6-plugin
  3. Join a Webex and have fun sharing your desktop!

Install Oracle Java to solve this issue

Press Ctrl+Alt+T on your keyboard to open a terminal window. When it opens, copy and paste the command below and hit enter. Input your user password when prompts and it will add the PPA repository into your system.

sudo add-apt-repository ppa:webupd8team/java

After that, update package lists via:

sudo apt-get update

To install Oracle Java 8, run:

sudo apt-get install oracle-java8-installer

Change the number 8 to 6 (or 7) in the code to install Java 6 (or 7).

While installation, you’ll be asked to agree the license and then the installer start downloading Java file from oracle website and install it on your system.

To set the default Java, run:

sudo apt-get install oracle-java8-set-default

Also change number 8 to the Java version you want.
