I have apparently been living under a rock for the past year or two. I have been using a dual screen setup without xinerama as I believed it still didn’t do accelerated GL and fullscreen videos took both/all displays. Well both of these things are history so everyone feel free to finaly enjoy the goodness of real dualhead desktop with xinerama. And thanks Bassam for the poke ;)
No wonder nothing is much happening on the separate X screen front. Both nautilus and GIMP started having issues. It’s because I’m the only one still running that :) Everybody else is enjoying the goodness of GL accelerated xinerama.
