I recently switched my main operating system from Mac OSX to Ubuntu with AwesomeWM, a tailing window manager. I notice a vast improvement in my ability to focus and definitely get into the zone quicker. Unfortunately it also broke the ability to watch video's full screen. Here is how I fixed it.
The problem
Here is a screenshot of a setup that I use pretty frequently when I am watching a video.
A video on the right, a twitter client - especially when watching a live stream -, and vim for taking notes.
But this setup breaks in awesomewm as soon as I switch the video to fullscreen.
The solution
The fix is pretty easy. We need to tell awesomewm how to handle plugin-container instances in a different way. It must not try to arrange them like other windows (the whole idea behind a tiling window manager), but just let it float on top of everything in the size it wants (fullscreen). To do so, add the following rule to your rc.lua.
{ rule = { instance = "plugin-container" },
properties = { floating = true,
focus = yes } },
After the change your can restart awesomewm by pressing modkey+control+r, or if that doesn't work, just logout and login again.
From now on fullscreen video will just work like you would expect it to work, fullscreen.
New instances will be floating fullscreen and get focus as they spawn. Just press ESC to exit them.
