On Ubuntu, finding a focused window while working is a little bit difficult. How can it be fixed?
I am working on Ubuntu 14.04 with two Full HD displays. The mistake I always make is typing to an unfocused window on the other display, believing the window has focus. I know its decoration is different from focused one, but by default it's too subtle to recognize at a glance.
How can I fix the problem? I installed CompizConfig and changed the weight of dropping shadow, but it wasn't enough.
