I would like to drag my windows to the left or right side of the desktop and have them automatically resized like it works with Gnome or Windows 7. And to maximize them when dragging them to the top. How is that possible in Xfce?
12.10 and above
Tiling snap is built into the XFCE window manager, just drag your windows to the edges of the screen for the snap to occur.
11.10 & 12.04
If you want the "tiling-snap" of compiz you will need to get your coding-hands dirty because this was made available as a code-patch for these two ubuntu releases.
There is a great you-tube video showing this in action.
I have applied this patch and uploaded this to my PPA.
sudo add-apt-repository ppa:fossfreedom/xfwm4 sudo apt-get update sudo apt-get install xfwm4
logout and login
If don't want to install the modified xfce window manager, you will need to use compiz as your compositing manager to enable tiling:
sudo apt-get install compiz compizconfig-settings-manager
compiz --replace ccp & to your autostart programs list.
For an easier instalation of xfwm-tiling you can use this tutorial: Building xfwm4tiling. Maybe you will have to change a couple of version numbers but it worked wonderfully for me. If not, you will allways have the compiz route. If you have a 32bit system i still have the .deb on my comp but i strongly suggest you to build it yourself.
