Dual Monitor Setup - How?


Hello there! First of all, I'd like to thank everyone on the forum for their previous help. You've all been great. I just got on the internet with Linux! Though, I'm an ambitious bastard... I want to set up a dual monitor system!

System details:

1.8 GHZ Athlon 2200+
GeForce 2 MX 32 MB (dual monitor support)
2 standard monitors (both accepted by linux)

Slackware 9.1
Fluxbox window manager

Got any idea how to do this?

All suggestions welcome.

Thanks guys!

My suggestion would be doing a search for "dual monitor" or for "xinerama" From there you should be able to find what you need.

Under the xinerama search, you should find several links on xinerama how-to, that's where I started.

OK, I'm back!

I found out I don't need xinerama... my graphics card supports twinview... see my ghx troubles (solved now) here..... http://www.linuxquestions.org/questi...hreadid=124870

the driver is here: http://www.nvidia.com/object/linux_d..._ia32_1.0-4496
readme is here: ftp://download.nvidia.com/XFree86/Li...496/README.txt

this is my XF86Config:

on latest stable Fluxbox btw.

i spent a week on dual monitors then found that the command
X --configure
is capable of building a dual-monitor XF86Config file. Of course it's not perfect, but might get you a ~working copy to start with.
Have you tried that?

(* jhill@leper pts/2 11:21 AM 133 *) - ~/install/OOo_1.1.0_LinuxIntel_install
> X --configure
Unrecognized option: --configure


I've always been looking for an easier way to do it :-( Guess this won't work either.

> X -version

XFree86 Version 4.3.0 (Red Hat Linux 9 release: 4.3.0-2.90.43)

sorry, late night. tried that on mine and it didn't work either. however this command:
X -configure
gives the following on my rh9 box:
Your XF86Config file is /root/XF86Config.new
To test the server, run 'XFree86 -xf86config /root/XF86Config.new'

I tried switching my second monitor with a newer one and it worked. But it wasn't my monitor, so I can't keep it.

It still doesn't work with my old HP monitor.. I'm not sure if the X --configure will make a difference, but I can give it a shot.

See this for more info about it: http://www.linuxquestions.org/questi...hreadid=124979

Well, if it's any help, here's an old XF86 of mine with dual monitor support.

http://www.technoslave.net/other/XF86Config.txt ( no, I won't turn it in to a link, because I'm lazy...so lazy, I'll type out an explination that's longer than me just creating the link! ) ( Hrm, I must have HTML on, or something, it auto created the link...woo freebies! Woo auto parse URLS! )

The important thing, I found, is really the BusID for the PCI slot.

Hopefully, you've found the commands like lspci and scanpci so that you know where your card resides. Also, not that I've looked, but I'd check nvidias site to see if they have anything about their dual monistor cards for linux...I'm not sure.

I can't use Xinerama cause it inteferes with the Nvidia driver... this is off one ghx card btw.

Thing is it that it WORKS perfectly with a newer monitor as a second one. It's just that my older (second) monitor isn't seen by the nvidia driver.

Are the refresh rates set too high for the old monitor?

If you're trying to setup dual monitors, such that 2 1280x1024 monitors = a desktop that is 2560x1024, then read Appendix R, which doesn't have anything about NOT have xinerama. If you're trying to do a two monitor, same display thing, then follow the first part about the twinview.

Other than that, make sure your BusIDs are right ( If it's an AGP card, they'll probably be something like 1:0:0 and 1:1:0 ), as well as your refresh rates on your monitors. From there it's just a matter of making sure that your Screens match up with your Devices that match up with your Monitors.
