So, my story is, 8.42 works for single head configuration, opengl is much faster, AIGLX is running though not so fast (especially when you have fullscreen apps). But, with dualhead configuration (not big desktop): first of all, gdm displays garbbish on my external monitor, although once logged in, gnome displays fine; secondly, opengl application only runs on 1st screen, and once they finishes glibc complains about double free or corruption; finally, AIGLX cannot run under dualhead...
BTW, I tried big-desktop configuration (I don't like it...), and gdm looks fine, but once logged in, it looks like the external monitor suddenly changed to clone mode and two monitors look identical...
