That's because debian still has this WINGs window manager which hasn't
seen any new releases since 2005: http://voins.program.ru/wdm/ and I'm
using it because I don't want the pompous crap of the other display
managers.

But this one uses /dev/mem as a randomFile only by default - there's a
configuration variable DisplayManager.randomFile which can be pointed
away from /dev/mem so that's easily fixable.

Mind you, I wouldnt've caught the issue if I wasn't using this ancient
thing in its default settings :o).
