Ubuntu 13.04 and paving the way to 14.04 LTS

On the cloud infrastructure side, the expansion of our ecosystem plays well into the diversification we see in technology choices along the cloud stack. Ubuntu now works seamlessly with various products such as Ceph for storage, Floodlight for SDN, and the Canonical-VMWare collaboration links OpenStack compute (Nova) to the ESX hypervisor. Offering a ‘High Availability’ deployment configuration for core OpenStack components such as RabbitMQ and MySQL helps meet service provider requirements for maximum uptime and reliability. We expect this to be extended to other Juju charms in the near future, offering a complete HA environment for cloud infrastructure.


Window snapping, popularised by the ‘Aero Snap’ feature of Windows 7, is a handy way to quickly display two applications side-by-side without overlapping, or maximise a window without needing to click a button.

For 13.04 a bit of attention has been given to the animation shown on screen to tell you that ‘you’re about to snap’. Developers have changed its appearance from that of a generic orange box spreading outwards to a semi-transparent copy of the window about to be snapped.

New Unity Preview Animations

Unity Previews, introduced last year in Ubuntu 12.10, are a great way to see more information about a search result without needing to open it up fully.

For the latest release the preview reveal animation has been tweaked, and applications icons at the edges of the preview “ghosted” save for the one being previewed.
Ubuntu desktop is the centralised ‘Online Accounts‘ dashboard.
Originally planned to arrive on the desktop last year is this – the new Ubuntu One Sync Menu. With a single click you can see whether you’re online; share a file; or check the status of recently uploaded files.
Ubuntu’s Bluetooth panel menu has been jazzed up with new toggle for turning on/off Bluetooth and visibility.
A core goal for Ubuntu 13.04 is to get Ubuntu running on a Nexus 7 tablet. To be clear, this is not going to be a tablet Unity interface running on the 8/16GB Nexus 7ubuntunexus7-large_001
But thanks to an inspired decision last October, Ubuntu 13.04 will use a mobile device as reference for tuning the core of Ubuntu. This will result into a smooth, snappy, and faster experience.

Ubuntu 12.04 LTS (Precise Pangolin) Beta 2

Ubuntu 12.04 LTS BETA 2 has just been released and it now available for download.

The BETA 2 is the last official release in the Precise development cycle, although release candidates are to probably land in the “open” for final testing days before the final release.

****************the stable and final version Long Term Support is expected on April 26.

Precise Pangolin BETA 2 introduces (since the BETA 1 version) a “fixed” Unity, meaning the visual bug present in both Ubuntu 11.10 and 12.04 pre-BETA 2 (the ghost-ish effect present in Dash’s icons) has been removed, thus Unity features now a clear/clean way of displaying icons.

The Precise Pangolin edition has been improved for low-power consumption, so now along with its new features and business-related support it may be the smartest choice for be implemented on laptops, keeping in mind that Canonical has already plans for Ubuntu on mobile devices.
Ubuntu 12.04 Precise Pangolin Beta 1 comes with the 3.2.0-17.27 Ubuntu kernel, which is based on the latest 3.2.6 Linux kernel, a feature that allows developers to work more easily on the maintenance for the period of five years of the LTS plan, for both server and desktop editions.

The Unity desktop interface (implemented from the version 11.04) now has reached the version 5.4 on Ubuntu’s beta 1 stage, with new options for system settings in “Appearances” and a quick search ensured by pressing the “Alt” key from the keyboard.

As you already know from the previous releases, Ubuntu 12.04 Precise Pangolin comes by default with the Rhythmbox media player (unlike Banshee in 11.04), that includes support for the Ubuntu One Music Store.

The new goodies coming in the beta 1 edition include the latest version of LibreOffice 3.5 and a brand new beta of Firefox 11.0, and hardware support for ClickPads.
For those who are using alternative versions of Ubuntu, we might add that the beta versions of Kubuntu 12.04 LTS and Xubuntu 12.04 are already in beta version 1 too, so you may download it for testing purpose in no time.

The name “Precise Pangolin” was announced by Shuttleworth on 5 October 2011. Unlike previous LTS releases that have been supported for three years for the desktop version and five years for the server version, this release will be supported for five years on both.

Ubuntu 12.04 LTS (Precise Pangolin) Beta 2


Ubuntu 12.04 LTS Precise Pangolin Beta 2The most stable and safe version of Ubuntu has arrived.


Ubuntu 12.04 Beta 1 is a long-term support release (LTS) that introduces a new set of images for the ARMv7 “hard float” ABI, denoted as armhf, among other new features.

12.04 continues Ubuntu’s proud tradition of integrating the latest and greatest open source technologies into a high-quality, easy-to-use Linux distribution,” the Ubuntu team reports in a blog. “The team has been hard at work throughout this cycle, introducing new features and fixing bugs.”

Some of the listed changes in Ubuntu include an updated LibreOffice (3.5 beta 2) and a switch to Rhythmbox as the default music player (which includes the UbuntuOne music store). Users also have access to a new HUD which provides a context-sensitive menu and search interface for Unity applications. Actual Unity settings can now be configured by the System Settings panel, and Nautilus support has been added to the Unity launcher.

The new version of Ubuntu also provides enhanced support for ClickPad devices. Now when a button is pressed on the trackpad surface, a second finger may be used to drag the cursor. Canonical’s Ubuntu Core has also been updated to include ARM hard float (armhf) images. Developers can use Ubuntu Core as the basis for their application demonstrations, constrained environment deployments, device support packages, and other goals.

“The technology that allows GPUs to go into a very low power consumption state when the GPU is idle (RC6) is now enabled by default for Sandy Bridge systems, which should result in considerable power savings when this stage is activated,” the blog states.

Install without using the package repository

Using the pre-built packages from the package repository is the easiest way to install the Canon drivers. If for some reason you prefer to use the older install method that does not utilise a package repository, read the following instructions.


The 2.3 driver is the latest release: Canon Linux CAPT 2.3 Driver Download

The 1.9 driver download page can be found here. Alternatively you can directly download the Debian package (recommended for beginners) or the Source Code.

Automated install using a BASH script

A script has been developed to automate the install of this driver on both kinds of architectures (amd64, i386). Unfortunately Canon doesn’t supply 64bit DEB packages and compiling the driver from source is a bit tricky. Therefore using this script is the best approach for users of 64bit Ubuntu, while for the 32bit users it’s just an automation of the manual install mode.

The 64-bit versions of the DEB packages have been built on an Ubuntu 9.10 x86_64 architecture, while the 32-bit ones used by the script are the ones supplied by Canon. The script and the drivers have been tested on Ubuntu 9.04 i386 and on Ubuntu 9.10 amd64 using a Canon LBP2900 printer.

The archive containing the script and the packages needed for the install can be found here. Please read the README file contained in the archive for more details or use the -h or –help command line options when invoking the script.

Adding a printer

Configuring CUPS

System->Administration->Printing add printer. Choose “Add printer”. Do not choose USB Printer found by Ubuntu here. Select “CAPT Printer”. You should see “ccp” in URI. Change it so URI should become “ccp:/var/ccpd/fifo0”. Click “next”, find your model and add your printer. Choose English variant if you see Japanese and English variants. Also If you do not have you exact model in list, choose nearest. For example, for LBP 810, I choose “LBP 1120”.

To look for available models you may use command:

$ find /usr/share/cups/model -name ‘*LBP*K.ppd’

Close configuration dialog, open again and rename your printer to, say, “LBP810”. Remember name you chose, as later commands will refer to it.

Instead of GUI actions, you may try this:

sudo /usr/sbin/lpadmin -p LBP810 -m CNCUPSLBP1120CAPTK.ppd -v ccp:/var/ccpd/fifo0 -E

Again, choose another .ppd name, if you have another printer…

Configuring Canon services

$ sudo /etc/init.d/ccpd restart
$ sudo /etc/init.d/ccpd status
Canon Printer Daemon for CUPS: ccpd: 8956 8954

If you see only one number at the end of line, edit /etc/ccpd.conf and add this:

DevicePath /dev/usb/lp0

Instead you may try this:

$ sudo /usr/sbin/ccpdadmin -p LBP810 -o /dev/usblp0

Next, check for record in /etc/ccpd.conf

For a network printer such as the LBP7200Cdn, the “DevicePath” should say “net:”, so for example if your network printer is on IP address, then the entry in /etc/ccpd.conf should say

DevicePath net:

Now, restart canon services:

$ sudo /etc/init.d/ccpd restart
$ sudo /etc/init.d/ccpd status
Canon Printer Daemon for CUPS: ccpd: 8956 8954

You should see two numbers at the end. If you do, you are lucky 🙂 If you only see one number here, then try restarting the computer, or possibly you could try replacing the ccpd start up script with the one on this page, and then restart the computer.

Starting/stopping on USB add/Remove

Fill /etc/udev/rules.d/85-canon-capt.rules with your preferred editor

$ gksudo gedit /etc/udev/rules.d/85-canon-capt.rules

with this:

KERNEL==”lp*”, SUBSYSTEMS==”usb”, ACTION==”add”, SYSFS{idVendor}==”04a9″, RUN+=”/bin/bash /etc/init.d/ccpd start”
KERNEL==”lp*”, SUBSYSTEMS==”usb”, ACTION==”remove”, RUN+=”/bin/bash /etc/init.d/ccpd stop”

Next, reload UDEV config:

$ sudo udevadm control –reload-rules

Now, using

$ sudo /etc/init.d/ccpd status

check that printer started/stopped on adding/removing it from USB.


mmarkk@imac:~$ sudo ccpdadmin

ccpdadmin [-p Printer-name -o Printer-dev-path]
ccpdadmin [-x Remove-Printer-name]

CUPS_ConfigPath = /etc/cups/
LOG Path = None
UI Port = 59787

Entry Num : Spooler : Backend : FIFO path : Device Path : Status
[0] : LBP810 : ccp : /var/ccpd/fifo0 : /dev/usb/lp0 :

Print a Test Page

At this point you can test your printer by going to: System->Administration->Printing

You should see a icon for the printer you have just setup. There maybe another printer in there with a similar name just ignore this one for the time being. Right click on the printer and choose properties. Click the buttons “Print Test Page”. Hopefully your page should print.

We have replaced the script to start the driver. Next we need to tell the system we want the script to start when the system next boots. This is where I had most problems with the ccpd daemon.

Restart and Verify

Now it is time to restart the system. If all goes well the system should restart and at the login page be able to print. This guide will not cover setting up cups for network printing.

After you login open a terminal and run:

sudo /etc/init.d/ccpd status
Canon Printer Daemon for CUPS: ccpd: 1135 1131

This shows the process Id’s for the two ccpd processes that should now be running. If you only see one then you still have a problem with the way the ccpd daemon is starting. Please check carefully you have completed all the steps above.

At this point you should be able to print a test page all being well.

If you run into problems try turning your printer off, restart your computer and only turn your printer on, after you have logged in.

Status Monitor

The Canon status monitor can alert you to any issues with your printer. This can be run directly on the terminal by issuing this command:

captstatusui -P
My printers example: captstatusui -P LBP3010

You will be presented with the User Interface and it should say ready to print. If not make sure the printer is switched on.

Finally we want the monitor to run each time the computer is switched so we add it to the as a startup application in: System Settings->Startup Applications

Click the Add button.

Name:Canon Printing Status Monitor

Command: captstatusui -e -P

Description: Hidden until error occurs

The -e option causes the monitor to stay hidden until an error occurs like when you run out of paper.


If Status monitor reports error “Check the DevicePath of /etc/ccpd.conf”, then you probably don’t have usblp kernel module. Run the following command:

lsmod | grep usblp

If it outputs nothing, load the module and restart ccpd:

sudo modprobe usblp
ls -l /dev/usb/lp0
sudo /etc/init.d/ccpd restart

Note: As of Ubuntu 11.10 (Oneiric Ocelot), usblp has been deprecated and will not be automatically loaded when you connect your USB printer (see bug #842823]).

If the status monitor works but printing does not, make sure that /var/ccpd/fifo0 actually exists:

ls -l /var/ccpd

When missing, it can be added manually:

sudo mkdir /var/ccpd
sudo mkfifo /var/ccpd/fifo0
sudo chown -R lp:lp /var/ccpd=======
