How to get WebEx running on an Ubuntu smoothly

Being 2016, there are a lot of ways to get on a video link between people.

While Skype, Viber, Whatsup or anything else can open a video connection and can be used between friends, in business world the options are a little bit more limited.

One of the option that is on par with the time is google hangout, and if your company has google apps, you can set up nice meeting, directly attached to your calendar invitation. It’s awesome and I like it a lot. My choice.

However, in biz space old habits are hard to die, therefore people stick to things like gotomeeting, which is not too bad, or the worse thing ever supported on Linux, WebEx.

To run the WebEx on Linux is a nightmare, to put it mildly. The WebEx is a java application, but they made sure that you can only run the 32 bit, and you can launch the applet only using a Firefox 32 bit installation. As I said, they may have their own reasons, but honestly I don’t really get it, and I think it is super crazy.

After battling with it for at least 4 hours, I found a reproducible way to get it going.

Here are the steps:

1) Install Firefox an 32 bit and some libraries for nice appearance.

sudo apt-get install firefox:i386 libcanberra-gtk-module:i386 gtk2-engines-murrine:i386 libxtst6:i386

2) Download the jre from oracle:

This is the link where you can pick the jre. Get the tar package, not the rpm http://www.oracle.com/technetwork/java/javase/downloads/jre8-downloads-2133155.html

3) Create a dedicated dir and untar it there

mkdir ~/32bit
cd ~/32bit
tar xvf ~/Downloads/jre-8u73-linux-i586.tar.gz

4) Add the plugin to firefox

mkdir ~/.mozilla/plugins

5) Link the plugin

ln -vs ~/32bit/jre1.8.0_73/lib/i386/libnpjp2.so ~/.mozilla/plugins/

Now you are all set!

In my test I was able to share the screen, to use the audio from the computer, and everything was working ok.

Good luck, and honestly, if you can, avoid WebEx.

Ubuntu: Black screen at the login

Today I’ve got a black (sad) screen after restarting the computer. The boot process was fine but everything seems to hang when the nvidia drivers was supposed to kick in and Xorg start.

It was impossible to fall back to any console text login type.

I’ve searched the internet here and there, but I was not able to find any solution or bug report, so I come up with an workaround.

I think the problem is due to the new kernel that I’ve installed following one of the suggested update and the incompatibility with the nvidia drivers. I don’t know if it is the true problem, but I have an hint that this can be true.

As the matter of fact I’ve changed the kernel at the boot time  (Push Esc when GRUB is showing the timeout for the default choice) and I choose the previous version (i.e. Ubuntu 8.10, kernel 2.6.27-12-generic).

With this one I was able to login and my system seems to be completely functional, up and running again.

For the time being I decided to stick with this kernel.  I edited the grub menu list (/boot/grub/menu.lst) changing the default 0 (Ubuntu 8.10, kernel 2.6.27-13-generic) with the second option (Ubuntu 8.10, kernel 2.6.27-12-generic).

Here my current menu.lst


# menu.lst - See: grub(8), info grub, update-grub(8)
# grub-install(8), grub-floppy(8),
# grub-md5-crypt, /usr/share/doc/grub
# and /usr/share/doc/grub-doc/.

## default num
# Set the default entry to the entry number NUM. Numbering starts from 0, and
# the entry number 0 is the default if the command is not used.
#
# You can specify 'saved' instead of a number. In this case, the default entry
# is the entry saved with the command 'savedefault'.
# WARNING: If you are using dmraid do not use 'savedefault' or your
# array will desync and will not let you boot your system.
default 2

## timeout sec
# Set a timeout, in SEC seconds, before automatically booting the default entry
# (normally the first entry defined).
timeout 3

## hiddenmenu
# Hides the menu by default (press ESC to see the menu)
hiddenmenu

# Pretty colours
#color cyan/blue white/blue

Arezzo goes OpenSource

Dopo una breve chiacchierata su IM scopro che il comune di Arezzo sta seriamente pensando di migrare al software libero. Uno dei progettisti di questa migrazione è Angelo Compagnucci, un amico di vecchia data, conosciuto tra i pinguini camerti del camelug.

Angelo è nel gruppo di migration manager, gruppo di ragazzi che si occupa di questo settore.

Quindi, buona fortuna ragazzi, e svecchiate un pò la nostra amministrazione (facendoci risparmiare un pò di soldi 😉 )

Go Arezzo Go (Open Source)!
