I've looked around on the web, and couldn't find any documentation
|
|
on setting up X with two monitors (myhost:0 and myhost:1)... I would
|
|
love to RTFM if anyone could point me in the right direction...

Thanks,

This would usually be called "multi-headed" mode and
|
|
the different screens would be addressed as "<tt>myhost:0.0</tt>"
|
|
and "<tt>myhost:0.1</tt>" -- "<tt>myhost:1.0</tt>" and
|
|
"<tt>myhost:1.1</tt>" (etc) would refer to a different server or
|
|
instance running on the same machine.
|
|
<br><br>
|
|
|
|
I don't know what this means on other forms of Unix
|
|
--- but I think you'd usually see it on a system that
|
|
was hosting multiple X Terminals via XDMCP. On my Linux
|
|
boxes I usually see it as an extra instance of the X server
|
|
running on a different virtual console (so my wife and
|
|
I can each have a running copy on any of the systems
|
|
around the house without having to disturb the other's).
|
|
<br><br>
|
|
|
|
In our case we run <tt>startx -- :1</tt> to start the 2nd instance
|
|
of our X server. We can then switch between them with
|
|
the [Ctrl]+[Alt]+[Fx] sequence (or the [Alt]+[Fx] sequence
|
|
to get to either of them from any of our text mode virtual
|
|
consoles. (If you don't use a PC Unix that supports
|
|
VC's this probably won't make any sense -- don't worry
|
|
about it).
|
|
<br><br>
|
|
|
|
Getting back to multi-headed support:
|
|
<br><br>
|
|
|
|
This depends on your X server. Last I heard XFree86 servers
|
|
(the suite of X servers that's most commonly used with Linux
|
|
<a href="http://www.freebsd.org/">FreeBSD</a>,
|
|
<a href="http://www.netbsd.org/">NetBSD</a> (PC) etc) don't
|
|
currently support multi-headed operation.
|
|
<br><br>
|
|
|
|
I know that some of the commercial X servers for Linux
|
|
(and presumably FreeBSD, etc) support it. Unfortunately
|
|
I've never used a PC or Mac Unix that was configured
|
|
this way. So, I don't know how it works. I've used an
|
|
old Sun system set up this was --- but I didn't configure
|
|
it or even look at it very closely --- it was just used
|
|
for some compatability at a place where I was working,
|
|
so I barely touched it.
|
|
<br><br>
|
|
|
|
I've used Macs that were multi-headed. That was a piece
|
|
of cake to configure. I also noticed that Win '98 has
|
|
this feature available --- so it might become much more
|
|
common in the next year or so.
|
|
<br><br>
|
|
|
|
Anyway, check out the XFree86 FAQ at
|
|
<A HREF="http://www.xfree86.org/">http://www.xfree86.org/</A>
|
|
for more pointers.
