So I just installed Ubuntu for the first time last night, so I qualify as an uber-Ubuntu noob. Anyway, the Alt-Tab switcher in unity, it just shows icons. At first I didn't think anything of it, until I saw some screenshots from someone else's machine that showed full window thumbnails.
To clarify, when I press Alt-Tab, I see a collection of icons for the various programs that I have open. If I hover over a program where I have multiple windows open, say the web browser, the view changes and it shows thumbnail images of what the windows currently look like.
Online, I've seen someone have an Alt-Tab switcher in unity that shows a window thumbnail for all open windows. This looks way nicer than the icon view, and coming from Windows I would prefer it. I just don't know how to make it that way.
I've used unity tweaks and compizconfig, but I haven't been able to get it to work. Any suggestions?
