11) KINO My first video editing experience on the Linux desktop years ago, Kino has always had a special spot in my heart for two very important reasons. First, it's always been among the most stable of all of the Linux video editors. Second, I am able to access dvgrab directly from within Kino's GUI. To my knowledge, Kino was the first Linux editor to provide direct dvgrab access. While the usage for this app is a little "odd," it's generally simple to use once you get used to it.
12) OpenShot video editor A definite newcomer to the video editing world on the Linux platform, OpenShot was a needed alternative to Kino for those looking to a GTK based solution. Providing a more standard means of editing video, OpenShot is fast becoming my video editor of choice when Im on the GNOME desktop. Plenty of desktop effects and control, I have yet to have a single worthwhile complaint with it to date.
13) Gwget2 It's surprising how many people out there are not taking advantage of the wonderful world of wget. I suppose it would possible that it's due to the lack of a GUI and need to use the terminal for such things, so this is where Gwget2 comes into play. Not only does this application put a friendly face to the trusted wget tool, you will also find it can detect whether you are downloading a multimedia or HTML file, right out of the gate.
14) Gnome PPP While most of us thankfully enjoy the wonders of broadband Internet, there are still a lot of people out there who are stuck with dial-up. Even though the project is widely considered as "dead," the fact remains that Gnome PPP still works and dial-up users appreciate the nice front end to Wvdial.
15) Evince I include this for the simple reason that Adobe Acrobat is worse than just about anything else out there for PDF handling. Evince is fast, stable and supports PDF files easily without missing a beat. While the software does support other formats as well, it's best known for its handling of those pesky PDF files we need to open from times to time.
16) Ekiga Before Skype, there was SIP. With SIP came great applications such as Ekiga. Thanks to some strong partnerships, Ekiga allows you to choose which company you want as a "phone" carrier whereas Skype dictates this to you. PC-to-Phone calls have never been so easy on the Linux desktop.
17) Dia Stable, easy to use diagram creation is no longer something that is only available for proprietary operating systems. Now users of the GNOME desktop can enjoy this functionality with a simple Dia installation. Despite this being a bit of a learning curve if you're already used to another program, for new users, it's a fairly straight forward experience when creating UML diagrams, flowcharts, network diagrams, etc.
18) Vino-server Remote desktop on your LAN need not be a time consuming headache. Despite being someone who prefers X11 forwarding through an SSH tunnel due to its strong security protections, I have found using Vino-serveron a secured LAN provides a safe enough environment for casual access to a remote desktop. And for GNOME-based desktops like Ubuntu, everything you need is already built right in for easy access.
19) Orca It's been said that user accessibility in Linux leaves a lot to be desired. Most of the time, however, this is said by individuals who have not taken the time to explore what Orca has to offer. From speech to Braille to magnification, Orca offers the bulk of what people need from their desktop environment from an accessibility stand point. The contributions in recent years to the Orca project have been nothing short of impressive, especially on the speech front.
20) Evolution The single biggest thing that keeps me using GNOME is the personal information manager (PIM) known simply as Evolution. Like Banshee, Evolution is a product of Novell but used for the GNOME desktop. Unlike similar PIM suites, Evolutions works with Microsoft Exchange properly and without relying on IMAP, which is a problem for many Exchange users where IMAP is not made available. Contacts, mail and calendar are all made plug-in-play available with Evolution.
