I spent a few hours the other day trying to troubleshoot a problem with a Compiz interaction on one of my machines causing high temperatures at lock-screen. I finally found that the problem had been intermittently reported for the last 2-3 years without much traction in finding a solution. My solution? Bypass that lock screen.
