Yes, you just install maximus...
sudo apt-get update
sudo apt-get install maximus
Then, open a run dialog Ctrl + F2 and type:
maximus
(you may have to log out and then back in)
.
Some windows like firefox will open with the window showing and all you have to do is use the mouse to tug down and then slam back up against the top panel to get it to go away. Otherwise, just click the maximize button once or twice.
Also, see this related article on how to put the close, maximize, etc buttons in the top panel: http://www.webupd8.org/2014/07/xubuntu-how-to-put-maximized-windows.html
If you are talking about this video https://www.youtube.com/watch?v=U-2KPrzIwao , the guy is using compiz to remove the window borders.
To install compiz, open a terminal and execute the following commands:
sudo apt-get update
sudo apt-get install compiz compiz-plugins compizconfig-settings-manager metacity dconf-tools
ccsm
Now, make sure the following plugins are enabled Composite, Gnome Compatibility, OpenGL, Move Window, Resize Window, Place Windows. Also, make sure the Window Decoration plugin is not disabled.
After enabling those plugins, run the following command:
compiz --replace
To enable window borders, open ccsm and enable the Window Decoration plugin.
see here on how to make compiz the permanent window manager
apt-cache search compiz | grep compiz
apt-cache search is broad and grep will narrow the results, andapt-cache show compizconfig-settings-manager
, for example, will show detailed info on a specific app.
