Linux Tutorial

Unity, the default shell in Ubuntu 11.04 and later will enjoy or not but it is undeniable to say that the developers have done a great job last year even considering that rely on graphics drivers on Linux often involves the appearance of bug directly attributable to the program that uses it.

A few days ago he attempted to Reddit question and answer session with the participation of the leading developers of Unity, which have declined to say as an introduction to their almost total alienation from the process design of Unity. So many questions, and especially so many interesting answers …

Apparently for Ubuntu 12.04 will undergo other interesting changes Unity (now private) that should not affect the stability of a suitable LTS. Among these, however, may not be able to change the location of the launcher and its much-desired thermization.

Ubuntu 12.04 should also be solved the bug that causes a crash if you want to enable/disable a plugin by Compiz Config Settings Manager.

Also interesting is the question “Why develop Gnome Shell Unity if we already have?”. Recalling that when the development of Unity has begun Gnome Shell proceeded rather slowly, Jason Smith (aka the creator of Docky BOD) pointed out that the latter did not like what they really were the technologies on which it was based. Sam Spillaz noted also that this would be like asking the question why there are competing projects such as Gnome, KDE and XFCE. Free competition in free markets in short.

P.S. major improvements are on the way to reduce the startup time to login.

After a month of continuous development, the team released version 3.4.0 Final LibreOffice, the first release of the new branch and to comply with 3.4 and “early adopters”. They are an amazing amount of news and you know them all by going to this page where you will find many screenshots and descriptions associated with the new features implemented.

In particular, we emphasize a new style of the dialog box for the option Move/Copy, improved HTML export with a gallery of thumbnail images of slides on the contents page, the fonts that are tuned for use with a specific script such as Arabic, Hebrew, malamayam, etc. are now showing a preview of the additional sample text in the target script, the ability to add and remove chart colors from Tools -> Options -> Graphics -> Default colors and many more new features!

I recommend very strongly to consult this page for the details and the new features of each application in the suite of LibreOffice.

Let’s see how you can install LibreOffice 3.4.0 on Ubuntu. You have two methods to do this: by using PPP or deb packages. In order to avoid errors or problems with OpenOffice, in case it is installed on your system, delete it. To do this open a terminal and type:

    sudo apt-get remove --purge openoffice*

Installing via PPP

To install LibreOffice 3.4.0 on Ubuntu we can rely on the official repositories:

sudo add-apt-repository ppa:libreoffice/ppa
sudo apt-get update
sudo apt-get install libreoffice libreoffice-l10n-it libreoffice-help-it

Currently, however, the PPAs are still stuck at version 3.3.2 and have to wait about a fortnight, perhaps to find updated:)
Installing packages by Deb

From the official website of LibreOffice you can download various formats for the installation of the suite on Linux and, among those present, you can also download the deb packages. Download and install LibreOffice, then the language pack Italian and finally help pack more in Italian!

Translated into commands, perform the following steps from the terminal but be sure to first remove the old version of LibreOffice on your system:

sudo apt-get remove --purge libreoffice*

Surely many of us have just installed the new Ubuntu 11.04 Natty Narwhal try to install Java. The problem is not present in the official repositories and as with the previous versions will be integrated into the Canonical Partner Repository. To date there are not yet available Canonical Partner Repository so if you want to install Java on Ubuntu 11.04 Natty Narwhal have to try other alternatives, the best in this case are the PPA LffL Java. Indeed LffL always ensures the latest stable version of Java on your PPA with the possibility of installing it on Ubuntu 11.04 Natty Narwhal (and earlier) and always have updated Java.

To install Java on Ubuntu 11.04 Natty Narwhal LffL Java through the PPA, just type in terminal:

always with the tab (the key above the caps lock) let you select the word YES in red and press enter.

Surely you tend to download many files from the Web, some also quite bulky, and often you rely on some download manager to better manage and track all the downloads you are doing.

And if you would simply schedule a time in which to download a file without having to rely on any software / tools to be installed outside? The Linux terminal, as I always say, if used well can be a real godsend for every need and also in this case, the combination of some commands will allow us to succeed in our goal.

In general, you should use the syntax is:

     echo 'wget indirizzo_del_file_da_scaricare'|at TIME

Where “address_of_the_file_to_download” should be replaced by the direct link to download the file and time with the time at which the download should begin. Here, for example, the syntax you can use to download the release candidate of Flash 11.0 at 20:30:

     echo "wget | At 20:30
     warning: commands will be Executed using /bin/sh
     job 1 at Wed Sep 9 20:30:00 2011

Message:

     warning: commands will be Executed using /bin/sh
     job 1 at Wed Sep 9 20:30:00 2011

We just indicates that the download will start at 20:30, 9 September 2011:)

The users will have beheld a miss of accessible GNOME 2 applet in Ubuntu 11.04. Let’s see how to reinstate them with no regrets as well as have regularly usually a click divided many cold features.

With a attainment of Unity, a Canonical group has private await applets embedded in GNOME 2, accessible programs which can perform a crowd of utilitarian functions for a user

Now they have been no longer available, we see how to reinstate regulating a indicator-applet: gentle indicators which Ubuntu allows we to supplement a complement tray right from version 10.04.

In these pages we will investigate a many utilitarian as well as interesting: If we have problems with a little applets we wish to inform latest or we can operate comments.

warning

Many of these indicators have been combined regulating outmost repositories managed by a developers, so in speculation out of a carry out arrangements for packets unfailing to Ubuntu and/or benefaction in Launchpad.

The designation involves a diminution in a confidence of your PC, afterwards we might wish to implement usually a smallest necessary, checking a integrity of a applet by searches upon a forums or upon a website of a programmer.
