[nycbug-talk] Xinerama in X.org

[Steven Kreuzer]

I have a Matrox G450 video card hooked up to two monitors. I have been 
running Xinerama mode in X.org without problems for a while
and I recently did a portupgrade on everything installed on my system. 
After that, I have been unable to get Xinerama to work at all.
I have been looking into this issue on and off for close to a month and 
I still have no idea what is going on.

$ pciconf -l -v

    vendor     = 'Matrox Electronic Systems Ltd.'
    device     = 'MGA G450 Dual Head Chip of G450 graphics card'
    class      = display
    subclass   = VGA

As far as I can tell, everything is setup correctly.

If anyone has any helpful advice, please let me know. I might be 
overlooking something
very obvious.
