Multi-head setups and X

Multi-head setups and X

Post by Hannu-Pekka Poikone » Sat, 24 Aug 2002 08:48:15



Hi all,

is there any kind of more or less complete list of functional multi-head
display adapter setups for X? I tried Google and www.xfree86.org but I
didn't find very clear answers.

I'm about to get another monitor soon and I'd like to use two screens with
one Linux box. Right now I have a 3Dfx Voodoo III 3000 display adapter and
I'm wondering if I have any hope of getting it to work together with some
other display card. Optionally I was thinking about getting a dual-head
adapter. Could someone tell me which option would be easier to setup or is
there significant difference?

Is this a Linux distro specific issue? Currently I'm running Redhat 7.2.
although I've been thinking about switching to Debian. Anyone have
experience of this?

Thanks in advance for your help.

regards,
H-P Poikonen

I think that most combinations of cards will work, just so long as there are
suitable slots on the bother board.

I've got an AGP Nvidia 2 and a PCI Voodoo 3 2000 working together in harmony
here. I suspect that getting a second graphics card rather then a double
headed card would be

* Easier to set up
* Cheaper

No, it just comes down to the version of X you have. The more recent the
better but any 4.x should be able to deal with Xinerama (one desktop,
multiple displays).

It is a good idea to get a Xinerama aware window manager. I use Openbox, but
KDE, Sawfish and most others work as well.

Thinking about emailing me? Only do so if it isn't apropriate for this
newsgroup. If it should have been in the group it will  probably be ignored.

no list i've heared of.. maybe ask for some sample configuration files...

basicly, every card that is supported by your X-server can be used in a
multi-screen setup as well. just plug as many agp/pci cards in your
system as your board can take and give X order to use them in a
multiscreen environment. the setup is quite simple from what i've seen
although i don't run such a setup myself due to the lack of free pci
slots - will anyone buy me a new board? ;-)
but i'm sure someone else will provide you with the propper XF86Config
file where you can see how to set things up.

I've seen the matrox g550 (or was it the 450?) running in dual-head mode
- but I assume it's gonna be cheaper and safer to just buy two (or more)
seperate cards each of which being supported by X.

not really although there might be some distributions allowing you to
set it up using a graphical frontend.

imho debian is the best distribution but requires some more knowledge of
your system and installed software. once configured properly, it runs
smooth for ages and even allowes upgrading without a reboot. as to your
dual-head thing, debian itself does not offer any gui frontend for this
configuration but as stated above, that shouldn't be the hard part.

1. multi-user: multi-head (monitor), keyboard, mouse, setup?

I have heard that Linux is just now starting to support "multi-head"
operation, with XFree86 version 4. Every reference that I have seen so
far is to one user having multiple screens with just one mouse and
keyboard. The comparisons I have seen are to Windows 98 or 2000, or
Macintoshes, where one person can have windows on multiple monitors.

I am wondering, since Linux is multi-user, and since support for USB
mice and keyboards is also coming into being, is it now possible,
given enough RAM,  to have just one PC, with multiple users logged
into their own X sessions, each with their own monitor, keyboard and
mouse?

If this is possible, how difficult is it to set up? How many users can
one put on one PC? I would guess it is the number of available PCI
slots that would limit it? Would using Matrox dual monitor graphics
cards double the number of monitors one could use for a given number
of free PCI slots? Is there a cheaper way than using USB keyboards and
mice to have many of them hooked into one PC?

What hardware should I buy if I want to do this now?

Thanks for your input!
