Disclaimer:

These are extreme memory tuning tips that might take some comfort away from your desktop. So make sure to have a backup and enough knowledge to undo those tuning tips.

Basic tuning by adjusting autostarted applications: If you installed a lot of applications some of the might put thereself into the autostart and will run everytime you fire up your computer (mostly in the background). If you don't want those applications to run at every start you can disable those by going to the menu -> preferences -> desktop session settings.

Advanced tuning by adjusting Lubuntus or LXDEs Autostart applications: Lubuntu and LXDE has some essential applications that will run everytime you start your system. These kind of programs manage your powersettings for your laptop or netbook or draw icons on the desktop. If you don't need these applications as you are using a desktop computer or simply don't need desktop icons you can disable those applications by editing the autostart script of the lubuntu session. This file needs root rights to be modified and is located under /etc/xdg/lxsession/Lubuntu/autostart.

Extreme tuning by adjusting the number of ttys(Notice: This only saves a few kBs of RAM): Lubuntu just as Ubuntu provides the user with 6 textconsoles besides the normal graphical user interface running ontop of Xorg. Normally you just don't need so much tty textconsoles and can disable them to save another bit of memory. To disable some ttys (leave at least one running for X crashes) you need to edit the configuration files in /etc/init/ttyX.conf (where X is the number of tty you want to edit). To edit them you need root privileges. You can than comment out the execute command at the bottom of each ttyX.conf.

So if you have gone through all this tuning tips you hopefully have saved some memory and have less memory consuming system up and running.

lubuntu 10.10 released

Taipei/Berlin/Paris, Oct. 10, 2010: Following intensive development Julien Lavergne, developement lead of lubuntu, announced version 10.10 of the lightweight desktop on October 10, 2010. lubuntu is a faster, more lightweight and energy saving Ubuntu variant using LXDE, the Lightweight X11 Desktop Environment. It includes a special selection of light applications combining easy usability and performance.

lubuntu is targeted at "normal" PC users running on low-spec hardware. Improvements of the latest lubuntu version include autologin support in ubiquity, support of install only mode in ubiquity, support for lubuntu-restricted package in ubiquity. lubuntu 10.10 comes with a completely new theme by Rafael Laguna. Lxpanel now supports Ubuntu indicators applets. Added applications and tools are Update-notifier, to get notification for available updates, Xpad, to create quick notes and Ace-of-penguins, to provide some games. Parcellite, which is not maintained upstream, was removed and Pyneighborhood was replaced by gvfs support of pcmanfm. LXtask replaces Xfce4-taskmanager for tasks monitoring. Evince is now used for reading PDF. During new installations a slideshow now describes features of the system.

Minimum requirements for lubuntu are comparable to Pentium II or Celeron systems with a 128 Mb RAM configuration, which may yield a slow yet usable system with lubuntu.

lubuntu features lightweight design work, faster boot speed and a smart choice of applications aimed at keeping resource usage low. The standard web browser is Chromium, the open-source version of Google Chrome. Besides speed the lubuntu team aims to offer the best possible compromise for new users offering easy to use application.

While lubuntu is developed with the end user in mind, its lightweight approach also makes it attractive to corporate users focusing on faster completion of tasks. Applications included are Sylpheed as e-mail client, Openbox as window manager, the file manager PCManFM, GPicView Image Viewer, Transmission for Bittorrent, Gnumeric for spreadsheets and Abiword for word processing. A new meta-package (lubuntu-core) is available to install only core packages of Lubuntu.  A new meta-package (lubuntu-restricted-extras) is available to install restricted packages for Lubuntu (such as flash, java and extra codecs for chromium). Additional applications are available through the packaging installation system Synaptic from Ubuntu repositories.

Features of lubuntu 10.10:

  • Faster boot speed through integration of lxdm, LXDE display manager
  • Low usage of system resources through Lightweight X11 Desktop Environment
  • Lower energy-consumption
  • Access to software repository through Synaptic software manager

Images for press use are available on https://wiki.ubuntu.com/Lubuntu/Marketing

lubuntu 10.10 is entirely free of charge available for download from http://lubuntu.net.

About LXDE

LXDE, the "Lightweight X11 Desktop Environment" is an extremely fast-performing and energy-saving desktop environment. Started by Hong Yen Jee known under his nick name PCMan, in Taiwan in 2005, LXDE is today maintained by an international community of developers. It comes with a beautiful interface, multi-language support, standard keyboard short cuts and additional features like tabbed file browsing. LXDE uses less CPU and less RAM than other environments. It is especially designed for cloud computers with low hardware specifications, such as, netbooks, mobile devices (e.g. MIDs) or older computers. LXDE can be installed with many Linux distributions. It is the standard for Knoppix and lubuntu and it also runs with  BSD. LXDE provides a fast desktop experience; connecting easily with applications in the cloud and supporting a wealth of programs that can be installed locally with Linux systems. The source code of LXDE is licensed partly under the terms of the the General Public License and partly under the LGPL. The website can be accessed under http://lxde.org.

About lubuntu

lubuntu was founded after a meeting with Mark Shuttleworth in Berlin during the Ubuntu Developer Sprint in February 2009 (Source: http://blog.lxde.org/?p=208). The desktop is currently among the top distributions on the page rank hit on distrowatch (http://distrowatch.com/index.php?dataspan=1).
