Dual monitor on T61
 
I've had a devil of a time trying to get dual monitor support to work for my T61. I'm running Fedora 8, x86_64. It has the Intel GM965/GL960 graphics controller.



I have two monitors connected. Both are Dell 2007FP's, that can run 1600x1200. Of course, one is connected via DVI, and other via VGA. I know the controller is capable of driving both monitors at the same time, because Windows can do it.



System-config-display cannot get it right. I have yet to fathom the mysteries of X configuration, and nothing I've tried thus far has worked. The best I've been able to do is to actually use the Ubuntu config file, which at least displays on the digital monitor. Tweaking the config (changing PCI address, changing driver to vesa) switches the output from DVI to VGA, but I cannot get both displayed at the same time. I'd love to have an extended desktop.



lspci -v and my current xorg.conf are below. Any help is greatly appreciated!



Thanks!
