Ubuntu 12.04 LTS est disponible en version finale depuis le 26 avril 2012 2) , cette version se définit comme étant la dernière version stable d'Ubuntu.

Modify Ubuntu - Ubuntu 12.04 Tips/Tricks. This will install the new Gnome 3 interface called Gnome Shell.
This will also install Gnome Classic, which is similar to Gnome 2 (the environment Ubuntu used to come with by default.)

Note: The following command will install KDE 4 without all the applications usually included with a full KDE install. sudo apt-get install kde-plasma-desktop.
Kernel/PowerManagementALPM. Aggressive Link Power Management (ALPM) is a mechanism where a SATA AHCI controller can put the SATA link that connects to the disk into a very low power mode during periods of zero I/O activity and into an active power state when work needs to be done.
Tests show that this can save around 0.5-1.5 Watts of power on a typical system. ALPM is now available in several SATA controllers that use the Advanced Host Controller Interface (AHCI). However, there is some anecdotal evidence that some controllers may go into a low power state incorrectly and this ends up causing data loss. Ubuntu has the ability to use ALPM but it it disabled by default since it can cause data loss on some machines.
We are looking for volunteers to test ALPM for 2 reasons: help to identify typical power savings on a range of machines help to identify chipsets (and machines) where ALPM works reliably and also where it is broken and needs fixing. NOTE: There is a risk in doing these tests. How to Test. Kernel/PowerManagementRC6. Testing is Closed The RC6 call for testing is now officially closed.
We appreciate all of the testing feedback we received. It had a direct impact and influence on our decision to enable plain RC6 by default for Precise. Between the testing feedback we received and interaction with the upstream developers, we were also able to find and fix a handful of RC6 related issues. Kudos to all involved. Kernel Power Saving Tweaks. There are some hardware specific power saving tweaks than cannot be fully applied by default as it causes problems on some hardware and we have yet to identify a suitable blacklist.
Enable Intel i915 RC6 NOTE: If you are running 12.04 LTS ("Precise"), this is already enabled by default. The Intel i915 RC6 feature allows the Graphics Processing Unit (GPU) to enter a lower power state during GPU idle. The i915 RC6 feature applies to Intel Sandybridge and later processors. RC6 was switched between enabled and disabled earlier in the Ubuntu 12.04 Precise LTS development cycle, but eventually all problems were fixed and it is now enabled by default.
On Ubuntu 11.10 and earlier, you need to enable it manually: edit /etc/default/grub (you need superuser privilege to do this) change: Kernel mis à jour. Power Management Laptop. Shell Extensions.

This seems to be working with any Asus laptop suffering from unexpected shutdowns and / or hangs while running on battery: 1. Add the following boot arguments _both_ to GRUB_CMDLINE_LINUX_DEFAULT and GRUB_CMDLINE_LINUX in /etc/default/grub.cfg: intel_pstate=disable pcie_aspm=force acpi_osi='Windows 2009' acpi_os_name='Windows 2009' Don't forget to execute sudo update-grub afterwards! 2.
