Compiz-Fusion Community News for February 9, 2008: KDE 4 is in.

kde4.jpgThe Community News returns again, after an absence that I will try to avoid in future P In the time between the previous community news and the last, there have been a number of new and interesting cool features added to Compiz-Fusion. The changes have taken place due to our community and our very own onestone who has added a slew of KDE 4 composite features to Compiz. Some highlights this week are:

  • KDE 4 Window decorator plasma integration

  • Show Mouse, and Area-Based maginification through the mag plugin

  • Wiimote integration

  • True blending of wallpapers and cubecaps

A number of bugs have also been fixed (Not the emerald crash at random, sorry!) which should improve your Compiz Fusion experience marginally.




News in Bugs

  • Temporary fix for certain windows loosing their shape attributes while using freewins (link)
  • Atlantis 2 works a bit better with normal monitors
  • Fix unnecessary compile warning with the screensaver plugin
  • Better option grouping in the Winrules plugin
  • Maximumize plugin was placed in the Window Management category
  • Individual plugin Makefiles were updated to notify the user as to when the plugin should be installed globally because it depends on other plugins

  • Ability to disable KDE4 support in compiz-fusion-debain platforms
  • Some working option support in the Wiimote plugin.

Design your own desktop with Xfce 4.4

Xfce is just as customizable as KDE or GNOME, so I set myself a goal: make Xubuntu look like Windows Vista. Why? Because I can. )

Though you won’t be told how to achieve the exact same end result (Microsoft™©® most likely would not appreciate that), this guide provides comprehensive instructions helping you make Xubuntu look the way you want it to. In any case, I would certainly not recommend such a setup for someone new to Xubuntu. Xubuntu is different than Windows; making it look similar is only confusing.

Wanna seek pleasure in confinement

SELinux is the way to go, if you wanna seek pleasure in confinement ;). SELinux is a real cool thing, which gives you the power to confine applications oselinuxn your desktop.

How to Kill/Close The Process in Linux.

Yesterday i was fed up :(,when i had closed vlc (video lan Player)on my linux ,but it still running in System Process…. and i don’t have any other way instead of logging off or shutting down and restart.

A lots of people likes to do kill -9, which means kill a process by force. By specified -9, process will be terminated by force, which is very fast and confirm kill but it leaves hidden side effects. Refers to Useless use of kill -9, kill a process by specified -9 may leave child processes of a parent orphaned, temporary files open, shared memory segments active, and sockets busy. This leaves the system in a messy state, and could lead to unanticipated and hard to debug problems.Application->System Tools->Terminal :

in the Terminal Type :

[puneet@localhost ~]$pkill vlc

It Solved my another Problem ,my vlc Becomes quite Understanding ,it exits whenever Commands :).

Definition: pkill: look up or signal processes based on name and other attributes.
