I installed RH 7.1 (GNOME desktop) and tried to configure Xinerama per the HOWTO. I get normal operation on the first monitor, but only the low-res gray screen on the second. But the cursor will go to it (as an "X", but buttons cause no effect). I'm attaching a .gz of my XF86Config-4 and the /var/log file. Did I miss a parameter? Appreciations, Gene
