I am trying to join a WebEx meeting from Ubuntu 12.04. I can join but I do not see the live chat messages, I hear no sound, and I cannot see the presentation. I have tried using Ubuntu 12.04 64-bit and 32-bit. The one time I was able to get it working, it was on 32-bit and the sound worked for a few minutes, but then stopped; I could see the presentation, but I could not see the chat messages. I have installed Oracle Java 7 from the webupd8 PPA and downloaded all Ubuntu updates as of today May 28th, 2013.
The WebEx system requirements page says they require Ubuntu 10.x or 11.x 32-bit. Does this mean in May of 2013 they do not support Ubuntu 12.04?!?
UPDATE May 29th: It seems I was looking at the old system requirements. It looks like these are the current WebEx system requirements. So, it says: "WebEx will support any Linux distribution as long as it meets the following minimum requirements:
- Kernel: 2.6 or later
- X Lib: X11R6 or later compatible
- C++ Lib: libstdc++ 6
- Desktop Environment, XFce 4.0 or later, KDE, Ximian, Gnome
- GDK/GTK. version: 2.0 or later
- Glib: 2.0 or later
- Sun Java 1.5 or later"
I am stilling learning about Ubuntu and Linux, but I know that Ubuntu 12.04 comes with a newer kernel (3.2), uses the X11 window manager, Unity is based on Gnome, and I installed Oracle Java 7. When I search the software center for these other packages I am a bit confused since there are so many options. I am guessing that my problem is not having one or more of these packages and/or incompatible versions. Does anyone have any insight on this?
UPDATE May 30th 10am EST. I tried installing ia32-libs as recommended here; same problem. I enabled the java console; here is the output:

Best Answer
For those of you who are still struggling with this...
I have tried many steps and recommendations from other posts and nothing has worked for me in Firefox (Ubuntu 16.04 64bit).
The only way for me to get Webex fully working was to install VirtualBox and then install Windows as a virtual OS. Yes, it's a bit inconvenient to run a virtual OS each time you need Webex, but you can be 100% certain that it will work perfectly (voice, video, screen sharing).
Good luck!
