Using Webex under Linux

Some of us have experienced troubles with having webex working fully and perfectly in our Linux environment. Thanks to several tutorials found on the Internet we managed to fix the various issues we encountered. Below is an "how to" for setting up your environment. We are using Ubuntu 14.04, 64-bit arch.

Webex is freezing / I can't see shared screens / I can't chat

Firstly, it seems that Webex is more willing to fully work and to be stable when starting a webex session from Firefox instead of Chrome. If you were using Chrome, give a try with Firefox before going deeper in this tutorial.

We started from this point :

As a summary : 

Execute the following command lines

$> sudo apt-get install libmux6:i386
$> sudo apt-get install libgcj14-awt:i386

This will fix a first set of issues. Then to check that all the required librairies are available on your computer, execute the following:

$> ldd $HOME/.webex/1324/*.so | grep 'not found'

This will give you the list of the missing libraries. Find the packages in which they are available using apt-file (if it is not yet installed, run $> sudo apt-get install apt-file)

$> apt-file search libraryName

For each library, install the i386 package, you might need libpangox-1.0-0:i386 and/or libpangoxft-1.0-0:i386. You can then try to attend a webex meeting.

I have no sound

Typically, if you try to use your headset you might see a message like this : "Audio device is unaccessible now". This section will help you with using your PC for voice. The solution we found is to use the 32-bits version of Firefox.

Download jre7 32-bits here

$> sudo apt-get remove firefox #uninstall the 64-bit version of firefox
$> sudo apt-get install firefox:i386 #install the 32-bit version of firefox
#Download java jre 32 bit, use the tar for 32-bit from the official website
$> mkdir -p $HOME/opt/java32/
$> mv Download/jre-7u60-linux-i586.tar.gz  $HOME/opt/java32/
$> cd  $HOME/opt/java32/
$> tar -xzvf jre-7u60-linux-i586.tar.gz
$> cd ~/opt/java32/jre1.7.0_60
$> mkdir -p ~/.mozilla/plugins/
$>ln -sf $PWD/lib/i386/ ~/.mozilla/plugins/

You can know try again to join a webex meeting and to use your computer for audio.
