The linux guys jumped on it quick as (I'm not ribbing by the way) - probably their guys came across it sooner than BSD users. What has thrown me is the fact that I didn't even consider it as a problem because I already had installed on a dual video system- ATI card and NVidia onboard, both that will work on a linux system, and that FBSD has no problem like this either; it just works. Weird... So what are my options then? I have 2 high performance cards I can't use? VESA is not exactly an exciting solution - or secure: it somehow retains the image displayed in memory, and shows it as it loads up X the next time.
