In Xubuntu 12.10, I am able to drag a window title bar to the top of the screen and it will maximize, but it will only maximize the top half of the display. Is there a way so it maximizes to the full screen like in Ubuntu?
Simple answer is no, this basic feature does not exist in Xubuntu. For some reason the Devs thought it would be a great idea to offer only half a maximised window. I hope that this feature will be added in later releases. Xubuntu is always improving!
Alt+F5 Maximize current Width
Alt+F6 Maximize current Height
Alt+F9 Minimize current window.
Alt+F10 Maximize the current window.
Or create your own shortcut using the Window Manager in the settings
