During this summer period, temperatures are starting to get really high, and often higher than what my computer can handle, apparently. Since a couple of weeks, I noticed a nasty white flickering taking over the screen after hours of use, with my integrated Intel HD Graphics 2000 on SandyBridge Intel i3 2120.
I tried to search for a solution but couldn't find anything that helps, except turning the computer off for some hours, thus letting it cool down. So this happens more and more often as uptime increases and at some point, it gets so frustrating that my only solution is to turn the computer down and do some other business. It happens more when running 3D games and also continues on tty sessions (even with X not running at all).
So I made a video to explain the situation to Intel GFX people on IRC, who sadly couldn't bring me much more help.
