Ok. Mozilla caused my X phase2v27 to crash miserably a few minutes ago. Restarting X gave me a bit of a surprise -- no more xinerama. I have
Option "Xinerama" in my /etc/X11/XF86Config-4 file, the same place it has been for weeks. I tried giving +xinerama on the command line. (That brought me into failsafe mode.) (BTW -- I am using Matrox's mga_drv.o file of Sep 23 on my Matrox G400Max.) It properly starts both monitors -- but I have no clue how to start a window manager on the second monitor, so it really doesn't do me much good. What on earth did I screw up? -- ``Oh Lord; Ooh you are so big; So absolutely huge; Gosh we're all really impressed down here, I can tell you.''
