Set nautilus-open-terminal to open xfce4-terminal

The nautilus-open-terminal is a nautilus extension that allows to open a terminal emulator on the current opened folder.
When installed in Xfce the extension opens xterm. To modify it so that it opens xfce4-terminal instead, run the following line in a terminal:
$ gsettings set org.gnome.desktop.default-applications.terminal exec /usr/bin/xfce4-terminal

Avoid brightness reduction

By default, when the computer is inactive for 120 seconds the screen brightness is automatically reduced. This is a great idea, except that the brightness is also reduced when playing a video file with VLC,  suddenly everything gets darker and is annoying to move the mouse every 2 minutes to restore the brightness level.

So to fix this all we have to do is get rid of this option. Open the Power Manager Settings and then on the "On AC" and "On Battery" sections select the Monitor tab. Adjust the third slider all the way to the left, as shown in the picture bellow.

Install Clementine Music Player (Amarok 1.4 fork) in Xubuntu 11.10

Amarok 1.4 was the primary reason for me to be using Kubuntu a few years ago. Simply put, it was awesome: it was simple to use and advanced features were included.

When KDE4 was released in 2008, Amarok went to version 2. It suffered so many changes that I felt that it lost its essence.

Clementine Music Player is a fork of Amarok's version 1.4 to port it to Qt 4.

Despite the fact that it is a Qt application and Xfce has GTK as its framework, I was so excited to have the good old Amarok back that I gave it a try. It met all my expectations and it works very well on my Xubuntu 11.10 environment; the keyboard multimedia keys work out-of-the-box (may I remind you that gmusicbrowser, the default music player on Xubuntu 11.10, doesn't support multimedia keys).

Clementines desktop integration is very good

To install Clementine on Xubuntu just type on a terminal window:
sudo apt-get install clementine
or

Click to install Clementine
