The blue screen of death screensaver is enabled by default. This should not be since it causes lots of problems with newer users who don't understand what is going on. We had is disabled quite a long time ago and it seems to have turned back on.
Since Fedora is targeted at developers and Linux enthusiasts, I figured those sorts of users wouldn't be bothered by it.
I know people that believed their Linux system had a virus because of BSOD and XFlame.
I wanted to strongly agree with the suggestion to default BSOD to "off". It's just not fun to spend a morning installing everything on a brand new machine, coming back from lunch, and seeing Linux death screens. Even a power user can be fooled. There's nothing wrong with including it in the distro, but I strongly agree that it should default to "off". Not everybody is a power user, and it makes Fedora (and Linux) look bad. (I turned it on but enabled only the funky retro crashes like amiga and apple ][ - brings back some great memories)
I've taken it out of the default random list in rawhide. I think that's a good compromise.
