1. Dual monitor on T61 (David M. Lee)

To: [email protected]
Message-ID: <[EMAIL PROTECTED]>
Content-Type: text/plain; charset=us-ascii
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!

*************************************************
On 27-11-2007 I posted a message on this subject with a solution. You'll
find the information below. However, not being able to get a better
resolution on the second monitor, I stopped trying to get it right, it
simply took me too much time. Maybe you can find out more.
NB. Since I have a graphics card from ATI, I don know what driver will
work for you.
Earlier message:
===
Dual head: I got it working also by using the right items in
/etc/X11/xorg.conf after installing the necessary driver by the command:
yum install kmod-fglrx (This is for the ATI card)
My copy of xorg.conf is:

===============
The desktop is stretched now over the two monitors, which was my aim.
The only thing still bothering me is the resolution of the second
monitor: 800x600, even though 1024x768 is mentioned in xorg.conf.

Hope this helps
