darktable is a digital photography workflow application for Linux and Mac OS X in the lines of Adobe Lightroom and Apple Aperture. The application is designed to ease editing and consistent processing of large photo sessions and provides a easy to use digital light-table and a set of sophisticated postprocessing tools. Most processing is done in 32-bit floating point per channel mode in device independent CIE L*a*b* color space. darktable is also fully color managed, which gives you full control over the look of the photos. The application relies on a modern plug-in architecture thus making it easy for 3rd party developers to extend the existing capabilities of the application. All light-table and darkroom features are implemented as plug-ins, so you can create your plug-ins reusing existing code. FEATURES: darktable runs on GNU/Linux / GNOME , Mac OS X / macports and Solaris 11 / GNOME . Fully non-destructive editing. All darktable core functions operate on 4x32-bit floating poin...

Ubuntu and other flavors of Linux don't really need cleaning up as you might do in Windows. Over time, of course, you might accumulate things on your computer that you might not wish to keep - old documents, no-longer-used programs, etc. - but there is nothing really akin to the Windows registry that simply builds up clutter that slows your computer. The old stuff you save won't slow down your computer: it will probably run as fast a year from now as it does today. To clean some packages laying around Run: sudo apt-get autoremove sudo apt-get clean sudo apt-get autoclean But you can do the following to clean up your computer: Installing ubuntu tweak: sudo add-apt-repository ppa:tualatrix/next sudo apt-get update sudo apt-get install ubuntu-tweak and then run ubuntu-tweak and there is an option called Janitor which is used for cleaning as seen in the picture: BLEACHBIT:   BleachBit  deletes unnecessary files to free valuable disk space, maintain privacy, and r...

Background The Gnome 3 comes with the old gnome-screensaver which is just a blank screen. XScreenSaver XScreenSaver is a collection of about two hundred free screensavers for Unix , Mac OS X and iOS . It was created by Jamie Zawinski in 1992 and is still maintained by him . The free software and open source Unix-like operating systems running the X Window System (such as Linux and FreeBSD ) use XScreenSaver almost exclusively. On those systems, there are two parts to XScreenSaver: the collection of screen savers; and the framework for blanking and locking the screen. In recent years, some Linux distributions have been using the gnome-screensaver or kscreensaver screen-blanking frameworks by default instead of the framework included with XScreenSaver. They still depend on the XScreenSaver collection of screen savers, which is over 90% of the package with the exception of gnome-screensaver version 3 and onward, which has dropped support for screensavers completely, s...
