Re: Matrox G400 dual head & xorg ?

That's correct, but the mga_hal module is not a kernel module. It's an xfree86 module.

I think the hal library needs to be present at xorg compile time, then it gets integrated into the mga_drv.o driver.

I will test this tonight, I think a procedure could be:

1. Install xorg-x11-6.7.0-5.src.rpm
2. Get mgadrivers-3.0-src.tgz from www.matrox.com
3. Unpack mgadrivers-3.0-src.tgz, copy
   mgadrivers-3.0-src/4.3.0/drivers/src/HALlib/mgaHALlib.a to
4. Make the following changes in /usr/src/redhat/SPECS/xorg-x11.spec:

$ diff orig.xorg-x11.spec xorg-x11.spec
< Release: 5
> Release: 6
> Source26: mgaHALlib.a
> cp %{SOURCE26} xc/programs/Xserver/hw/xfree86/drivers/mga/HALlib/
< #define UseMatroxHal            NO
> #define UseMatroxHal            YES

5. Run: rpmbuild -bb xorg-x11.spec
6. Wait a long time.
7. Upgrade xorg using the new rpms in /usr/src/redhat/RPMS/i386/

NOTE NOTE NOTE: This is untested, I will try this when I get to my
G400Max machine tonight.

Instead of upgrading the RPMS, you could try if this works:

A: cd /usr/X11R6/lib/modules/drivers/
   mv mga_drv.o mga_drv.o.orig
B: On one line:

cp /usr/src/redhat/BUILD/xorg-x11-6.7.0/xc/programs/Xserver/hw/xfree86/drivers/mga/mga_drv.o .

C: Restart X
D: If X doesn't work any more, copy mga_drv.o.orig back
