X configuration for xinerama using NVIDIA acceleted driver and an ati card

I am trying to configure X so it is a multihead display. Right now I have a Riva TNT2 Ultra card running as a single display using the NVIDIA drivers (not "nv"), so the NVIDIA card is not the problem. The other card I have is an ATI Mach 64 VT.

When installing the NVIDIA driver, I had to add in the Module section of XF86Config-4 this line:

Load "glx"

I have had this setup working using just the "nv" driver, so I am pretty sure that the above line in the file is causing a problem with the ati card. Here is the part of /var/log/XFreee86.0.log that I think is relevant:

(**) NVIDIA(0): DPMS enabled
(II) Loading extension NV-GLX
(II) Loading extension NV-CONTROL
(==) ATI(1): Write-combining range (0xd8000000,0x100000)
(WW) ATI(1): RENDER extension not supported with a shadowed framebuffer.
(II) ATI(1): Largest offscreen areas (with overlaps):
(II) ATI(1): 800 x 54 rectangle at 0,600
(II) ATI(1): 576 x 55 rectangle at 0,600
(==) ATI(1): Backing store disabled
(==) ATI(1): Silken mouse enabled
(II) Entity 0 shares no resources
(II) Entity 1 shares no resources
(II) Initializing built-in extension MIT-SHM
(II) Initializing built-in extension XInputExtension
(II) Initializing built-in extension XTEST
(II) Initializing built-in extension XKEYBOARD
(II) Initializing built-in extension LBX
(II) Initializing built-in extension XC-APPGROUP
(II) Initializing built-in extension SECURITY
(II) Initializing built-in extension XINERAMA
(II) Initializing built-in extension XFree86-Bigfont
(II) Initializing built-in extension RENDER
(II) [GLX]: Calling GlxExtensionInit

Fatal server error:
Caught signal 11. Server aborting

is there somehow I can disable that glx line for the ati driver? Or does anybody have any suggestions?

shouldn't be too hard. I've been messing up xinerama for weeks.

in you XF86config-4 file just comment out the line in the module section for glx. for a single driver may be trickyer though. let me look into it

if you want to use Xinerama then i'm abuot 95% sure you can't use the glx module. Xinerama totally messes around with the video settings.

then again tho i can't use glx with a normal dual hed setup - i.e. without Xinerama.

i would like to also state my opinion that Xinerama is naff....
