My most trouble-free period was when I was using Xubuntu exclusively for several years with a single monitor. Now I've been using Windows again for several years and I've grown accustomed to things just not working, ever, with tons of visual lag, usually just a few hundred milliseconds but sometimes stretching into seconds. On Xfce I would sometimes idly hold down win-t to create a bunch of terminals then alt-d to close them one by one. As I might idly bounce a pencil up and down back when I used pencils. On Windows/OSX/Gnome I would never dream of just idly opening a bunch of applications for fear of what might happen.
