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


----------------------------------------------------------------------

Subject: Dual monitor on T61
To: fedora-laptop-list@redhat.com
Message-ID: <24269.15877.qm@web36711.mail.mud.yahoo.com>
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!

dave

*************************************************




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.

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)

===============

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

Thanks for the advice. I tweaked your config to work for my Intel chipset, with not-so-happy results.

If I set the driver to 'intel', I get single screen out the DVI. However, whenever the screen saver pops up, X exits and take me back to the login screen. If I set the driver to 'vesa', I get single screen out the VGA. But when I boot disconnected from the docking station, video on the LCD is 800x600.
