5 New Unity 4 Games Will Come to Linux

We've announced a couple of weeks ago that with the release of the Unity 4.0 game engine more games will be published on Linux, especially on the Ubuntu platform, via Ubuntu Software Center.

In the last days, more game studios have announced that their "still in development" games will have native support for the Linux platform.

Without further ado, here are the five new games announced (you can click on each one to view its homepage):

1. FORCED, a gladiator combat-game based on tactical cooperative 2-4 player gameplay either online or locally (also includes full single-player game), published by Beta Dwarf.

2. Blackreef Pirates, a single-player adventure RPG (role-playing game) set in a unique fantasy world full of treasure maps, wild beasts, and rum, published by Subvert Games.
3. Kinetic Void, a SciFi Space Sandbox, which focuses on procedural content, and detailed customization, published by Badland Studio.

4. Folk Tale, a real-time comedy-adventure-strategy game published by Games Foundry.
5. Receiver, a game that explores gun handling mechanics, randomized levels, and unordered storytelling, published by Wolfire Games.
All these games and hopefully much more will be available for Ubuntu users, via Ubuntu Software Center, as soon as they are finished and the Unity 4.0 engine is out.

Unity 4.0 is developed these days by Unity Technologies, which are getting ready to release the final version of the award-winning game engine, and a collaboration with Canonical will make sure that game developers can publish their games directly into Ubuntu.

And to be honest, I just can't wait for both Unity 4 and Valve's Steam to break the ice, to destroy that giant door that keeps Linux users away from all those nice games we see on our neighbor's computer!

Bring 'em on, guys, I want to buy your games!

In this tutorial we will see how to use the Recovery Mode to reset a lost password so that you can log in again to your desktop. We will also help you set your computer to login automatically without entering the user password. You can use this tutorial on Ubuntu 12.10/12.04/11.10/Linux Mint 13 or older.

Another menu will appear after a few seconds, select the line saying "root Drop to root shell prompt" and press Enter to enable the CLI mode:

The file system in this case is set to read-only which will prevent us from resetting the user password. To set read/write permissions, you need to run this command:

mount -rw -o remount /

If you have also forgotten your username, you can use this command to get the list of all system user accounts:

cat /etc/passwd

Once you decide which user to reset password for, run this command:

passwd username

Note: Replace username with your own user name.

Submit a new password two times for this username. If the operation is successful, you may get something like this:

Run now this command to exit:


Then select the "resume normal boot" option to load your OS in normat mode.

   Enabling Automatic Login (Optional)

To make Ubuntu/Linux Mint start automatically without stopping at the login screen, follow these instructions:

- Open the terminal and run this command:

sudo gedit /etc/lightdm/lightdm.conf

For Linux Mint 13:

sudo pluma /etc/lightdm/lightdm.conf

- In this file, add your username as follows:

IPFire 2.11 Core 62

Michael Tremer has announced the release of IPFire 2.11 Core 62, a specialist distribution of Linux for firewalls: "Today, we are releasing the 62nd Core update for IPFire 2.11. This update fixes some security problems and also adds some new functionality. We recommend that you update your IPFire installations as soon as possible if you are using the outgoing firewall in mode Fixed: outgoing firewall permits hosts on BLUE to access the Internet. In earlier releases, it was possible for hosts on the BLUE network to access resources on the Internet which are allowed by the outgoing firewall although no permission has been granted to the host (blue access). This is a moderate risk." Read the rest of the release announcement for additional information.
