[Xpert]Matrox G400 Dual Head
I'm trying to get a Matrox G400 dual head card working with XF86 4.2. The only documentation I found was under 4.1, so if there is something newer, let me know. The 4.1 docs said to set it up just as if you had 2 cards, but to use the same BusID in both devices section. I tried that, but still only got one head. The log file recognized the dual-head setup: (**) |-->Screen "Screen0" (0) (**) | |-->Monitor "Monitor0" (**) | |-->Device "Card0" (**) |-->Screen "Screen1" (1) (**) | |-->Monitor "Monitor1" (**) | |-->Device "Card1" (**) |-->Input Device "Mouse0" (**) |-->Input Device "Keyboard0" Later it says: (II) MGA: driver for Matrox chipsets: mga2064w, mga1064sg, mga2164w, mga2164w AGP, mgag100, mgag100 PCI, mgag200, mgag200 PCI, mgag400, mgag550 (II) Primary Device is: PCI 01:05:0 (WW) MGA: More than one matching Device section for instances (BusID: PCI:1:5:0) found: Card1 (--) Chipset mgag400 found Otherwise it looks like a single head setup. I am using the Matrox HAL library, but not the linux drm module as I don't need 3D. Is this supposed to work? If so any ideas what I'm doing wrong? I've attahced my config file and log file.` -- Chris BareMetro Link Incorporated [EMAIL PROTECTED] http://www.metrolink.com/ Xerrors.0.log.gz Description: gzip compressed data, deflated, original filename, `Xerrors.0.log', last modified: Thu Apr 11 11:23:32 2002, max compression, os: Unix XMetroconfig.gz Description: gzip compressed data, deflated, original filename, `XMetroconfig', last modified: Thu Apr 11 11:27:48 2002, max compression, os: Unix

You need something at the kernel level (fbdev or dri are obvious thoughts) to stop 2 user processes (such as the X server) from fighting over the hardware. DRI doesn't split the dual head into 2 separate heads. The most likely possibility is the (linux) kernel frame-buffer driver. I've never tried it but the linux kernel has an option for dual head on Matrox cards; if that makes the card appear as something like /dev/fbdev0 and /dev/fbdev1, there is an X server driver (possibly fbdev) which should be able to run on one of these devices. If it works, this would effectively give you 2 separate cards. You then need to consider something like http://cambuca.ldhs.cetuc.puc-rio.br/multiuser/ in order to get a different keyboard working on each head. I assume that you don't want to use VT switching to get one keyboard onto both servers. -- Dr. Andrew C.

[Xpert]Matrox G400 dual head, 2 X servers?
I have a Matrox G400 (dual head). I want to be able to run two separate X-server instances, one per head. Is it possible? How about running an X-server on the first head and a frame-buffer on the second? Somehow I doubt the latter even more than the former. Thanx. b. -- Brian J.
