The Ubuntu Linux distribution has received a major update today. The new version, Ubuntu 9.10, will introduce several significant new features and will deliver the latest version of the GNOME desktop environment and other applications.

This is the eleventh release of Ubuntu since the project’s inception five years ago. The distribution has achieved an unprecedented level of popularity in the Linux desktop ecosystem and has attracted a considerable audience. Canonical, the company behind Ubuntu, touts the new release as its best yet and says that the latest improvements will take the Ubuntu user experience to the next level.

Some applications like TweetDeck don’t respect gnome preferred applications settings and continue to use the older Firefox 3.1 instead of the new one 3.5 when opening links.

This is because

/usr/bin/firefox is currently pointing (like a shortcut) to

/usr/bin/firefox-3.0

To change this to 3.5 enter the following on the command line

sudo ln -sf /usr/bin/firefox-3.5 /usr/bin/firefox

If you want to change it back:

sudo ln -sf /usr/bin/firefox-3.0 /usr/bin/firefox

This will work for Firefox 3.5 as well as Shiretoko 3.5
This will also fix same issues with other Adobe Air applications

I just upgraded to 9.04.

I have got to say that this is the most solid and polished Ubuntu yet. It Rocks!
No mayor new features as development was concentrated on stability, reliability and speed. They delivered!

Upgrade went without issues at all. Even my nvidia dual head setup that was always a problem with upgrades was handled perfectly.

Zero problems!

Upgrade took 1.5 hours TOTAL, using the Costa Rica mirror. With the MIT mirror it would have taken 13 hours.

HIGHLY recommended!

This is a nice way of keeping your secured passwords synced in all your computers and laptops, even cross-platform. Colin has a nice summary:

Tell me if this sounds like you: you have a few standard passwords that you routinely use for every site you visit. One of them you use for sites that don’t contain too much personal or sensitive information, and maybe you use one or two for sites that do. If you want to be REALLY secure you have another password that you only use for bank or credit card sites that contain your most sensitive information.

This is what I used to do (for many years in fact). Then I got to thinking: what happens if someone discovers one of those passwords? If it were one of the more sensitive ones, I’d be in deep trouble. So, I set out looking for a better way to manage my passwords.

What I’m going to describe in this article is a system I’ve implemented to manage my passwords in a secure, cross-platform way. It’s by no means the best way to do things for everyone, but it’s worked out extremely well for me thus far.

The VNC client bundled with Ubuntu, Vinagre, works half the time. Fortunately, we can also VNC with the installed “Terminal Server Client”

The “VNC” option with the default installation of Terminal Server Client is disabled or grayed-out.

To enable it you need to install the xtightvncviewer package in Synaptic or with the following command on the terminal

sudo apt-get install xtightvncviewer

Done!

UPDATE: To also enable the XDMCP protocol option, sudo apt-get install xnest
