Weird, this time I did get Firefox to run the flash video fullscreen. After I exited fullscreen, I got the flash code written all over my desktop, burned into it, so to speak. Then I tried Chrome, did get fullscreen, but right after I exited, there was complete lockdown again. dmesg output appended.
