Lock computer but keep the display on
How can I prevent the display from turning off when the computer is locked?
I usually lock my computer when I leave the desk with ⌃⌘Q or ⌃⇧Power. The first way keeps the display on for a few seconds, the second one turns the display off immediately. When I return and hit any key to wake it up I have to wait a few seconds before the monitor wakes up and I can input the password.
