[Westwales] Mandriva and dual monitors, among other things

[Jon Pearse]

   Well, I eventually got around to having another go at getting dual 
monitors working, and an hour of messing around means that, instead of 
having my external monitor show a neutral grey, it now shows an odd 
yellow tartan-esque pattern which looks as though it could be a mirror 
of what's displaying on the main screen, but ... not quite ( 
http://morawel.ath.cx/~jon/funkiness.jpg ).
   For whatever reason, xorg doesn't seem to be realising that I can 
drive two displays, so it's either complaining that it can't find the 
other screen, or that I've got a duplicate device definition for the 
graphics card... or it complains because Mandriva's setup insists on 
putting double quotes in the DeviceName field, and when it's tired of 
that, it also complains that it's missing a ModeLine statement. Oddly 
enough, it only does this when the statement is there... if I delete 
the line, it shuts up.

   Ideas? (xorg.conf attached)

 Some people come into our lives and quickly go. Some stay for a while
 and leave footprints on our hearts. And we are never, ever the same.
