<div style="text-align: justify;"><b>KDE SC 4.10 has been released</b> today with many improvements and additions, including a new QML-based screen locker, additional KWin effects and scripts thanks to GHNS (Get Hot New Stuff) integration, a new print manager, a new Air theme and wallpaper and many improvements to Kate, Dolphin, Konsole, Okular, Gwenview, Kontact, re-written typing tutor and more. </div><br /><div class="separator" style="clear: both; text-align: center;"><a href="http://4.bp.blogspot.com/-Fjh86zdLy-E/URK2E4FcyiI/AAAAAAAANY0/wwWcavyUAew/s1600/kde-sc-4.10.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img alt="KDE SC 4.10" border="0" height="206" src="http://4.bp.blogspot.com/-Fjh86zdLy-E/URK2E4FcyiI/AAAAAAAANY0/wwWcavyUAew/s320/kde-sc-4.10.png" title="KDE SC 4.10" width="320" /></a></div><br /><b>More information about the latest KDE SC 4.10 can be found here:</b><br /><ul><li><a href="http://kde.org/announcements/4.10/plasma.php">KDE Plasma Workspaces</a></li><li><a href="http://kde.org/announcements/4.10/applications.php">KDE applications</a></li></ul><br /><div style="text-align: justify;"><b>As usual, the Kubuntu team has been super fast and the latest KDE SC 4.10 is available for Kubuntu 12.10 or 12.04 users in the Kubuntu Backports PPA, so here's how to upgrade.</b></div><br /><a name='more'></a><br /><br /><h2>How to upgrade to KDE 4.10 in Kubuntu 12.04 or 12.10</h2><br /><div style="text-align: justify;">Before adding the PPA, please note that according to the PPA description, the packages in the Kubuntu Backports PPA might not be tested enough yet, so you may encounter bugs!</div><br /><div style="text-align: justify;"><b>The Kubuntu backports PPA provides the latest KDE SC 4.10 for (K)Ubuntu 12.10 and 12.04 (I've only tested it in Kubuntu 12.10). To add the PPA use the following commands:</b></div><pre class="linux-code"><code>sudo add-apt-repository ppa:kubuntu-ppa/backports<br />sudo apt-get update</code></pre><br /><div style="text-align: justify;"><b>Then, open the Update Manager, make SURE all the packages are selected and install all the available updates</b>.

Later on if you want to remove KDE, simply run "sudo apt-get remove PACKAGES", where "PACKAGES" is the list of packages that were installed by the "sudo apt-get install kubuntu-desktop" command.<br /><br />After all the packages have been successfully installed, it's probably a good idea to restart the system.<br /><br /><b>If the Plasma theme has some visual glitches</b> when opening the menu, see the <a href="http://www.webupd8.org/2013/02/upgrade-to-kde-sc-410-in-kubuntu-1210.html#comment-791061657">comments</a> below.</div><br /><br /><div style="text-align: justify;"><i>P.s.: if you want to download the KDE SC 4.10 new default wallpaper, you can get it from <a href="http://www.webupd8.org/2012/12/download-new-kde-sc-410-wallpaper.html">HERE</a>. </i></div>

<div style="text-align: justify;">Ubuntu 12.10 and 12.04 use the PAE Linux Kernel by default for 32bit ISOs and while you could use the <a href="http://www.webupd8.org/2012/05/how-to-install-ubuntu-1204-on-non-pae.html">mini ISO to install Ubuntu 12.04 on computers that don't support PAE</a>, that's not possible in Ubuntu 12.10.</div><br /><div style="text-align: justify;">Further more, with 12.10, Xubuntu and Lubuntu no longer come with a non-PAE Linux Kernel, so by default, you can't install any Ubuntu 12.10 flavour on computers using CPUs that lack PAE support (such as Intel Pentium M).<br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="http://2.bp.blogspot.com/-2SbZ38kbLhM/UK-pWsOxVaI/AAAAAAAAMFo/tFrloEqd4qs/s1600/ubuntu12.10-non-pae-kernel.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img alt="ubuntu 12.10 non-pae" border="0" height="240" src="http://2.bp.blogspot.com/-2SbZ38kbLhM/UK-pWsOxVaI/AAAAAAAAMFo/tFrloEqd4qs/s320/ubuntu12.10-non-pae-kernel.png" title="ubuntu 12.10 non-pae" width="320" /></a></div></div><div style="text-align: justify;"><br /><b>Below you'll find instructions on how to install Ubuntu 12.10 Quantal Quetzal on computers that don't support PAE</b>.<b> The instructions have been tested on the default Ubuntu 12.10 ISO (with Unity), but they should work with any Ubuntu flavour like Lubuntu, Kubuntu, Xubuntu and so on and probably Linux Mint 14 as well</b>.<br /><br /><div style="text-align: justify;">Using the resulting bootable Ubuntu 12.10 USB stick, it should also be possible to upgrade from Ubuntu 12.04 to 12.10, but I've only tested it on a clean installation.</div></div><br /><a name='more'></a><i>Physical Address Extension (PAE) is a feature to allow (32-bit) x86 processors to access a physical address space (including random access memory and memory mapped devices) larger than 4 gigabytes.</i><br /><br /><br /><h2>Install Ubuntu 12.10 Quantal Quetzal on computers that don't support PAE</h2><br /><div style="text-align: justify;"><b>1.</b> Download the required files (includes non-PAE Linux Kernel 3.5.0 deb files).</div><br />You can grab all the required files as once, using BZR:<br /><pre class="linux-code"><code>sudo apt-get install bzr<br />cd<br />bzr branch lp:~webtom/+junk/linux-image-i386-non-pae</code></pre><br /><div style="text-align: justify;">Or, you can download each file manually from <a href="http://bazaar.launchpad.net/~webtom/+junk/linux-image-i386-non-pae/files">HERE</a> (click the green download image on the right). </div><br /><br /><div style="text-align: justify;"><b>2.</b> Create a <a title="4 Ways to Create Bootable Live USB Drives (For Windows, Linux and Mac OS X)" href="http://www.webupd8.org/2009/04/4-ways-to-create-bootable-live-usb.html">bootable USB stick</a> with the Ubuntu 12.10 32bit ISO and once the stick is ready, open it in your file manager (.e.g. Nautilus) and replace the following files from the USB stick with the files downloaded under step 1:</div><ul><li>rename the downloaded "vmlinuz-3.5.0-17-wt-non-pae_3.5.0-17.28_i386" file to "vmlinuz" and copy it to the USB stick, under the "casper" folder, replacing the already existing "vmlinuz" file.</li><li>rename the downloaded "initrd-3.5.0-17-wt-non-pae_3.5.0-17.28_i386.lz" file to "initrd.lz" and copy it to the USB stick, under the "casper" folder, replacing the already existing "initrd.lz" file</li></ul><br /><div style="text-align: justify;"><b>3. </b>Copy the following downloaded files to the USB stick (don't place them in any sub directory):</div><ul><li>linux-headers-3.5.0-17-wt-non-pae_3.5.0-17.28_i386.deb</li><li>linux-image-3.5.0-17-wt-non-pae_3.5.0-17.28_i386.deb</li></ul><br />Note that these are the <b>3.5.0-17</b> Linux headers and image, not 3.5.0-18!<br /><br /><div style="text-align: justify;"><b>4.</b> Now you can use the USB stick to install Ubuntu 12.10 on the non-PAE capable computer. Once the installation completes, DO NOT REBOOT the computer, press CTRL + ALT + F1 and in the tty, type the following commands to install the non-PAE kernel you've copied to the USB stick under step 3:</div><pre class="linux-code"><code>cd /cdrom<br />sudo dpkg --root=/target -i *.deb</code></pre><br />Some warnings will be displayed when running the above command:<br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="http://4.bp.blogspot.com/-AmXiMJs0Ous/UK-p3uYZRMI/AAAAAAAAMFw/H6R1Lk7VBpk/s1600/install-nonpae.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img alt="ubuntu 12.10 non-pae" border="0" height="176" src="http://4.bp.blogspot.com/-AmXiMJs0Ous/UK-p3uYZRMI/AAAAAAAAMFw/H6R1Lk7VBpk/s320/install-nonpae.png" title="ubuntu 12.10 non-pae" width="320" /></a></div><br /><div style="text-align: justify;">ignore these warnings and once the installation completes, reboot the system (you can press CTRL + ALT + F7 to switch back to the installation and reboot from there or type "sudo reboot").</div><br /><div style="text-align: justify;"><b>5.</b> Your computer should now boot the newly installed Ubuntu 12.10 Quantal Quetzal flavour. From the files downloaded under step 1 (or, if you don't have access to them any more, redownload just the ones below), copy the following files to some folder that doesn't have any other deb files, e.g. your home directory:</div><ul><li>linux-image-3.5.0-18-wt-non-pae_3.5.0-18.29_i386.deb</li><li>linux-headers-3.5.0-18-wt-non-pae_3.5.0-18.29_i386.deb</li></ul><br /><div style="text-align: justify;"><i>This is the latest Linux Kernel version available in the Ubuntu 12.10 repositories (3.5.0-18 and not 3.5.0-17 which we've used under steps 3-4). </i></div><div style="text-align: justify;"><br /></div><div style="text-align: justify;">And finally, install these deb files:</div><pre class="linux-code"><code>cd #if you've placed the files in your home directory<br />sudo dpkg -i *.deb<br />sudo apt-get install -f</code></pre><br /><div style="text-align: justify;">That's it! </div><br /><div style="text-align: justify;">Unfortunately, there's no PPA (that I know of) to use for non-PAE Linux Kernel updates, so when a Linux Kernel update is available in Ubuntu, don't install it and instead, check if a newer Kernel has been added to the <a href="http://bazaar.launchpad.net/%7Ewebtom/+junk/linux-image-i386-non-pae/files">BZR repository</a> used in this post and install it using "sudo dpkg -i *.deb". Or, compile your own kernel.</div><br /><br /><div style="text-align: right;"><i>Instructions adapted from <a href="http://bazaar.launchpad.net/~webtom/+junk/linux-image-i386-non-pae/view/head:/README">HERE</a>. Thanks to Thomas Reith for the instructions and non-PAE Linux Kernel deb files.</i></div>
