[XFree86] Multihead monitor maximum limit

2003-02-11 Thread Widiarto



Hi all,
 
I wonder how many VGA adapter that XFree86 server 
can handle to use multi head monitor? I've already tried 4 and it work!.. I 
wanna try more than 4 but my motherboard only have 4 PCI :((.
I see on the website there is industrial PC 
backplane which has 18 PCI, is it possible if I use all 18 PCI with 18 VGA 
cards? Does anyone have tried this?
FYI, windows 2000 can support until 10 VGA and 
windows 98 until 8 VGA
 
Best Regards,

XFree86 can support upto 16 screens at the moment, there's nothing stopping
you increasing that limit. The define for this is in

xc/programs/Xserver/include/misc.h 

and look for MAXSCREENS.

Different drivers etc may or may not work though. Certainly a good 
percentage of drivers have never been tested with that many heads.

We have tried 16. I don't recall what MAX_SCREENS is currently.
You may have to increase it and recompile.

MAXSCREENS (defined in xc/programs/Xserver/include/misc.h) is
currently 16.

Any recommandation for a multihead PCI graphics board ? (I have seen a 
multi-TNT2 board, but this is not too exciting )

hands on one of these and comes trolling.

True, however we do have a size limit that's harder to overcome:
the x/y dimensions of the screen must fit into a signed (!) short.

Now, does one really need the high resolution.
Typically the bigger the display gets the further 
away one goes.
A lower resolution doesn't matter then.
