How does dual-heading work?

Post by Matthew McClear » Tue, 13 Jun 2000 04:00:00



I am considering running a dual-head configuration on my RH6.2 box. I have
an STB V4400 AGP card that will drive one monitor and an ATI Xpert 98 PCI
card that will drive the other. How does one go about setting this up? Is it
even possible to do dual-head without a GUI? I would like to possibly put
compiles and syslog on one monitor (i.e. a 15" or smaller) and everything
else on the bigger monitor. Would this be possible? I welcome suggestions.

Also, I don't know which graphics card would be faster for GUI work. The
V4400 has a TNT chip, but that's mostly good for 3D stuff--I wouldn't see
much if any benefit unless I was playing games--at least, I think so.

Can anyone relate any personal experience in this area? I've gotten SMP up
and running (dual Celerons), so now it's on to the next challenge.

Thanks,

Never did it on a PC, and I'm not sure about doing it without X, but...

X allows two different configurations for dual-head.

The two monitors can be separate "screens" on a single display.  Meaning
that a single X server controls them both.  I think both must be set up
as the same color depth and visuals for this to work.

Alternatively, they can be separate displays.  Meaning that two X
servers will run - one for each monitor.

There are advantages and disadvantages with each possibility.

For ordinary apps, you specify the display you want the app to launch on
using the "-display" command-line preference, or the DISPLAY environment
variable.

For a single app to open windows on two different screens (or two
displays), I think the app will have to be designed for this
functionality.

1. Doing dual head with 2 cards...

Hello, I have a bit of a technical problem, and a money problem.  I'm
poor.  :P
   But anyway, I'm going back to school this year, and I thought it would
be very nice to have a two moniter setup for programmming.  So I stuck two
cards in my machine, and got two monitors.  One card is an 'nVidia Corp.
GeForce 256' the other a 'Cirrus Logic GD 5456'.  Or, in other words, One
nice 3D accelerator and an old pice-a-poo PCI SVGA card.  (4 megs maybe?)
Well, windows delt with it fine.  So this setup is happily running under
windows XP. Then, I heard Mandrake would probably be the easiest Linux
dist. to do this under, so I installed Mandrake 8.2.  Mandrake detected
the two cards and said "You can have a 2 head system here, how would you
like to do it?  1. Configure all heads together 2. Use Xinerama extention
3. & 4. Just do one of the two cards."  
        Well, I fiddled around a lot with all the options, and I can't get
it to work.  Oddly enough, even when I try to configure only the Cirrus,
all the testing and stuff shows up on the nVidia's moniter.  Strange.  Any
help Guys?  Thanks
