Another interesting bug fixed regards the compatibility with the graphics acceleration drivers Intel: has been released a patch for the architecture MESA 9 was eliminated of obsolete code and – attention – has been eliminated close dependence, at compile time, by libGL (and consequently to GLX and xlib, this core library of X.org) : translated into terms human, this means that GNOME Shell has begun to take into account the replacement of X.Org with Wayland / Weston.

How to Use your USB Flash Drive (USB Token) to Log into your PC under Ubuntu/Linux Mint

In this tutorial, we will help you create secure way for logging in with the help of your USB stick to your session. Once setup, you will no longer use your user account name and password to log in, just insert your usb device and click Log In:

To do this, we will use PAMUSB which is a module for PAM (Pluggable Authentication Modules) that allows users to have authentication from a USB device. It is compatible with many display managers (LightDM, GDM, etc.).

Getting Started

Open the terminal and run this command to install required packages under Ubuntu 12.10/12.04/Linux Mint 13:

sudo apt-get install pamusb-tools libpam-usb

Connect your usb flash drive to your computer/laptop and run this command to add it to PAM (the usb device will be detected automatically):

sudo pamusb-conf --add-device usb-key-name

Replace usb-key-name with any name of your choice. You will be prompted to save your configuration to /etc/pamusb.conf, type Y and press Enter:

Let's now add your username to PAM so that it will be granted access to your desktop via the USB drive. To do this, run this command:

sudo pamusb-conf --add-user username

Replace username with your own user account name. Or run this command which will detect automatically your current username:

sudo pamusb-conf --add-user=$USER

Type again Y and press Enter to save:

Edit now this file to make sure PAM is using the pam_usb library:

sudo gedit /etc/pam.d/common-auth

For Linux Mint, replace gedit with pluma. These lines must be available in /etc/pam.d/common-auth:

auth sufficient      pam_usb.so 

auth [success=1 default=ignore] pam_unix.so nullok_secure try_first_pass

Save your file and close. Next, run this command to check if the username you have added is authenticated to login with the USB device:

su username

or

pamusb-check $USER

If everything goes well, you will get these outputs:

$ su upubuntu 

* pam_usb v0.5.0 

* Authentication request for user "upubuntu" (su) 

* Device "upubuntu-usb-key" is connected (good). 

* Performing one time pad verification... 

* Regenerating new pads... 

* Access granted.

You can now log in to your user session without submitting your password as along as the USB device is connected.

How To Bypass WiFi Bandwidth And Time Restrictions Under Ubuntu 12.10/12.04/Linux Mint 13

In some places (airports, network rail stations, etc.), you may have access to free WiFi so that you can connect to the internet via your laptop. However, most of these public facilities may not allow for an unlimited use of WiFi and they set time/bandwidth limits for each connected user.

In this tutorial, we will see a trick that will allow you to enjoy unlimited WiFi without any restrictions, but keep in mind that this may not work for all users because it depends on many factors.

Getting Started

When connected to the Internet, your laptop is identified by a MAC address which cannot be changed unless you use some third-party tools. Under Ubuntu/Linux Mint, we can use MACCHANGER to modify a machine's MAC address. You can install it under Ubuntu 12.10/12.04/Linux Mint 13 or older with this command:

sudo apt-get install macchanger -y

Let's now identify your wireless network interface (wlan0, wlan1, etc.) with this command:

ifconfig

For my system, it is identified as wlan0:

Let's now disable the WiFi connection with this command:

sudo ifconfig wlan0 down

Change now your MAC address with this command:

sudo macchanger -r wlan0

You will get prompts about your current and new MAC addresses:

$ sudo macchanger -r wlan0 

Permanent MAC: 00:a1:b0:0b:7d:de (unknown) 

Current   MAC: 00:a1:b0:0b:7d:de (unknown) 

New       MAC: 1e:b6:72:ee:8d:42 (unknown)

Now relaunch your WiFi connection with this command:

sudo ifconfig wlan0 up

Don't forget to delete all your browsing history and cookies. When WiFi time/bandwidth limits are reached, change again your MAC address.
