What’s the point of using XFree86 with QNX? Doesn’t that mean Photon-based apps wont work? Doesn’t that leave you with basically the same options as you have with linux, except QNX has a differnt kernel?
Its for those people who want to say they run QNX but really just want linux with a prettier boot loader
I haven’t tried it, but AFAIK X & photon (can) run at the same time (like Aqua & X on MOSX). I seem to remember a screenshot of GIMP (on X of course) running while other photon apps run on <http://www.qnxstart.com>.
