Bug#420419: WIth two video cards



Hi,

I'm basically having the same problem (same segfault), but I can't find the correct way to configure my X server with the new intel driver.
In fact I'm using two very different video cards for my xinerama setup: one i845G (driver intel) and one old Matrox Mystique (driver mga). I couldn't find any information about the new configuration with this type of setup, so I would appreciate a lot to get some help for this issue.

Here is an excerpt of my new xorg.conf (I removed the sections about the keyboard and DRI) :

Section "Device"
    Identifier    "matrox"
    Driver        "mga"
    BusID        "PCI:1:0:0"
EndSection

Section "Device"
    Identifier    "Intel"
    Driver        "intel"
    BusID        "PCI:0:2:0"
EndSection

Section "Screen"
    Identifier    "Default Screen"
        Device          "Intel"
    DefaultDepth    16
    SubSection "Display"
        Depth 24
        Virtual 2048 2048
    EndSubSection

    SubSection "Display"
        Depth 16
        Virtual 2048 2048
    EndSubSection

EndSection


I tried using two Device lines in my Screen section, and got some weird results; I tried with using +xinerama when starting the server, or without.

I must say I could make it work in "two independant screens" mode (only the screen on the matrox card was a bit weird, but I suspect I'll have to try a preferred mode for that).


Here is the relevant part of my old xorg.conf

Section "Device"
    Identifier    "Intel Corporation 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device"
    Driver        "intel"
    BusID        "PCI:0:2:0"
EndSection

Section "Device"
    Identifier    "Matrox Mystique"
    Driver        "mga"
    BusID        "PCI:1:0:0"
EndSection

Section "Monitor"
    Identifier    "Philips 170S"
    Option        "DPMS"
        Gamma           0.8
EndSection

Section "Monitor"
    Identifier    "NEC MultiSync FE950+"
    Option        "DPMS"
    HorizSync    30-96
    VertRefresh    50-160
EndSection

Section "Screen"
    Identifier    "Default Screen"
    Device        "Intel Corporation 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device"
    Monitor        "Philips 170S"
    DefaultDepth    16

    Lots of SubSection "Display"
EndSection

Section "Screen"
    Identifier    "Second Screen"
    Device        "Matrox Mystique"
    Monitor        "NEC MultiSync FE950+"
    DefaultDepth    16
    Lots of SubSection "Display"
EndSection

Section "ServerLayout"
    Identifier    "Default Layout"
    Screen        "Default Screen"
    Screen        "Second Screen" RightOf "Default Screen"
    InputDevice    "Generic Keyboard"
    InputDevice    "Configured Mouse"
EndSection


And I used to start X with the +xinerama option.



Thanks for having read until this ;)
