For the uninitiated, the features list can be found here.
My understanding of this release is that it'll be a playground for many cutting edge features. Stability is definitely not one of the key goals. What are your plans for this release? Production? Playground? Testing? Skip it? Let us know in the comments!

This post discusses the easy way of restoring Grub2 using Ubuntu Live CD. First, boot with the Ubuntu Live CD. Now mount the partition, which has Ubuntu installed on it. If you had a separate partition for /boot, then you would have to mount that too. Mounting the partitions is super easy. Just go to Places in the top Gnome menu and try browsing to your corresponding partition by clicking on it. It would automatically get mounted and open in nautilus.
Now just run the following command to install Grub2 in the Master Boot Record (MBR) of your first booting hard drive.
sudo grub-setup -d /media/XXXXX/boot/grub -m /media/YYYYY/boot/grub/device.map /dev/sda
Where XXXXX represents the name or UUID of the partition that you have mounted. If your /boot partition is separate from your / partition then YYYYY above would be different from XXXXX, else both of them would be identical. The command above assumes that /dev/sda is your primary or first device in hard disk boot order. If not then replace it with /dev/sdb or sd_ fill the blank with appropriate letter.
After you have run the command, reboot and you should be able to boot in Ubuntu but not in Windows, to fix it run the following command in a terminal and Grub boot list would be updated to include Windows in it. Also if you want to change boot order read this.
Now reboot and you should have the choice to boot in both Windows and Ubuntu.
sh extract.sh;sudo cp *fw /lib/firmware
sudo apt-get install mercurial libncurses5-dev
hg clone http://kernellabs.com/hg/saa7164-stable/
sudo make install
from the command line
then install MythTV using whatever method you like, I personally went into synaptic and installed the frontend and backend and extra plug-ins
once installed and you set up your passwords go to
System> administration> MythTV backend setup
once there go to Capture Cards, Should be choice #2
choose new capture card, you will ave to do this step twice (this card has two tuners)
At card Type, pick DTB DTV
the first will be device number 0,
repeats choosing capture card to add the second tuner
the second device will be #1 (Linux starts counting at 0, good thing to know, especially for hard drives)
then go to video sources, pick your options, will vary so mine will not work with yours most likely, so I dont want to post something I dont know)
then go to Input Connections, again you will have 0 and 1, configure both
then edit channels and directories as needed.
close let it fill database, for some reason mine keeps running in a loop, just exit after you see it finish the first or second time
now go to Applications > Sound & Video > MythTV Frontend
And you should be able to watch TV

sudo apt-add-repository ppa:ricolai/ppa
sudo apt-get update
sudo apt-get install rdesktop
It appears ricolai may have removed the package from his PPA. To remedy the situation, I've uploaded the working binaries for x64. Sorry, I don't have the x86 any longer.
More information on the bug can be found here:

echo "deb http://ppa.launchpad.net/jason-scheunemann/ppa/ubuntu `lsb_release -cs` main" | sudo tee -a /etc/apt/sources.list && sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys CD30EE56
Now install SopCast with
sudo apt-get update && sudo apt-get install sopcast-player sp-auth
Run with Alt+F2 -> sopcast-player or get it at Applications -> Sound & Video -> SopCast Player.
For more US based channels, try Justin.TV instead. It even has the option of pausing a show and coming back to it later.
I use Compiz' multiple desktops using the rotating desktop on all my machines that support 3D acceleration. I typically mentally map where all my apps are in relation to each other so that I can quickly switch to the workspace I need to perform a task. However, I sometimes find myself wondering where I left Firefox open, for instance. Having the option to blow up the whole cube on the desktop is nice, but I found the Overview display of Gnome-Shell to be even better.
For me, anything that reduces clicks is a good thing. The overall interaction with Gnome-Shell as compared to Gnome is just that; simpler. I don't know how to explain this other than to say I was making fewer clicks and finding things much faster than before. I don't understand why people bash this as much as they do. It really did make me work more efficiently than before.
If you have a test system you can do it on, I recommend giving it a try. I have a feeling it will be integrated more fully at some point in the future for Ubuntu, but for now, I only recommend it for testing or messing around with. I'm sure the community would love to hear your feedback as well, so please feel free to post in the comments!

See more information on this here.
Also, to enable rotating the desktop cube with the mouse wheel, set rotate left to button 4 and rotate right to button 5 in the bindings for the mouse.

Before I do anything:
*Update the system! I use a mirror close to me, such as UC Davis' math dept.
*Install the proprietary drivers for my system (for my Dell D630, it's the Wireless STA driver and the latest Nvidia driver).
*Run this script and install the pieces I want (adds repos automatically - nice!).
Some others suggestions:
Install ubuntu-restricted-extras. Should give you the default Sun Java stuff as well as Flash (though, if you're using the 64bit distro, you'll end up reinstalling it using the proper build. See my earlier post on this).
Need games? Try PlayDeb.
To play encrypted DVDs, the libdvdcss2 package is essential. libdvdcss is a simple library designed for accessing DVDs like a block device without having to bother about the decryption. Once you have Medibuntu repo available, just install it from there.
Use Google? Try googsystray - an all-in-one notifier and useful app.
I've found that the Flash plugin for 10.04 is less than spectacular out of the box. I suspect it has something to do with the 64bit OS and found this article explaining how to fix things up.
Basically, here are the steps:
- Download 64bit installer.
- Close browsers
- Make installer executable, run it.
- "Remove Flash"
- Add 64bit Flash
With the release of 10.2, we're basically back to square one again. However, I found a slightly better method of getting the latest version installed this time around. Since it relies on someone's PPA, it may or may not work for forever, but here's what I did *this time*.
sudo add-apt-repository ppa:sevenmachines/flash && sudo apt-get update && sudo apt-get install flashplugin64-installer
After that, if you want 10.3 or later, you need to download the .tar.gz from Adobe Labs (64bit version, that is), extract the .so and replace every same-named .so on your system.
Add these lines to the end of /etc/apt/sources.list
deb http://mirrors.ucr.ac.cr/medibuntu/ hardy free non-free
deb-src http://mirrors.ucr.ac.cr/medibuntu/ hardy free non-free
run the following:
wget -q http://medibuntu.sos-sts.com/repo/medibuntu-key.gpg -O- | sudo apt-key add
then run the following:
sudo apt-get update

- Requires the Sun JRE/JDK, not the OpenJRE/OpenJDK installed by default.
- Requires the 32bit JRE, not the 64bit JRE
Switching from OpenJRE/JDK to Sun's version (without uninstalling, due to dependency issues).
Setup the 32bit JRE to run alongside the 64bit, and Download and modify the junipernc script by pointing it to the 32bit version. To do this, add this line after the # lines at the beginning:
export JDK_HOME=/usr/lib/jvm/ia32-java-6-sunTest your setup here when you're done.
To reconnect after disconnecting, you might need to relogin to the vpn website and then run the connection script again. The session doesn't always exit nicely.
The big downside to all this is that you'll now have 3 different Java environments installed on your machine. Figuring out which one is running for what can be a bit tricky. It would be ideal for Ubuntu to allow either environ to begin with, but I understand why they can't do that.
- Eclipse 3.5.2 is finally in the repo! Finally, we're getting some love from the guys at Ubuntu on this. No need to install from source any more.
- Boot time/Login time. MUCH faster than my ext3 based 9.04 was.
- Nvidia driver support. Multi-monitor setup is much more stable than before. Seems to even remember that I have 2 monitors attached to the laptop. Very slick compared to 9.04.
- Software center. I didn't think I'd like this because they tossed out the ratings system for now, but actually, I really like it. It displays any newly added repos I grab from Launchpad in the same area as the defaults. I can even view apps available in one repo vs. the others.
- Stability. I can't emphasize this enough - bells and whistles are nice and all, but this version is just rock-solid so far. Love it on my laptop.

I kept getting this error:
The artifact file for osgi.bundle,org.eclipse.cvs,1.0.400.v201002111343 was not found.
Here's the fix:
sudo apt-get install eclipse-pde

That's a big claim. How can I say such a thing? Aren't all Linux distros essentially built on the same foundation? Well, yes, they are. But then again, all cars run on four wheels. What sets Ubuntu apart isn't the fact that it's Linux or even that it's Debian-based, it's the people behind the effort. Ubuntu's core team, Canonical, is doing something no other Linux distro has been able to do. It's giving guidance on and meeting the expectations of the average user. And it's doing it at a rate that's significantly outpacing all of its competitors.
Ubuntu has been the #1 distribution on DistroWatch since 2005 with its closest competitor being Fedora (which it consistently leads by a 30 to 50 percent margin). To find out more about why it's been able to hold this position and gain ground from both the Windows and Mac markets, read this article: Ubuntu, the Ultimate Linux Distribution. And a further clarification here.
With Lucid Lynx just 6 days away, the soon-to-be 20M users worldwide have again turned to Canonical for direction on the next big thing. And they haven't been disappointed. Read more about the recently announced 10.10,
