I'm looking for a lightweight way to snap windows in Lubuntu. It's possible to install compiz, but doing so will make the system far less lightweight. Are there any alternatives or workarounds?
You could use the lightweight compositing manager used by XFCE called xfwm4
This will give you basic windows snap.
N.B. if you dont like the default "change workspace when dragging a window off the screen" capability then untick the very last option shown in the picture.
However - if you want the "tiling-snap" of compiz you will need to get your coding-hands dirty because this is work-in-progress.
According to this article - there is a potential patch available to enable windows tiling (aka windows snap) for the xfwm4 compositing manager.
Through the following Q&A I have packaged this tiling patch into my PPA - instructions for installation can be found in the linked answer.
There is a great you-tube video showing this in action.
To use xfwm4 as your compositing manager instead of OpenBox.
In Desktop Settings - Advanced options change the window manager to xfwm4
Now in terminal:
cd ~/.config/lxsession
mkdir Lubuntu
cp LXDE/* Lubuntu/
Install the compositing manager:
sudo apt-get install xfwm4-themes
Logout and login for the xfwm4 compositing manager to take effect.
Change the style via xfwm4-settings
