Hello all,
I'm trying to have a working dual screen setup on a 7500 and I think I'm
a bit confused on what to do... I'm using the onboard video and an
additional ATI 3D Rage LT Pro. The kernel boots with
'video=controlfb:vmode:16,cmode:24' and the console is fine on the
onboard video.
I've setup XFree to use the two cards and two monitors but I can't have
my second screen working. The monitor doesn't seem to get in synch with
the video card. I've tried multiple things and don't know more what to
do. I'm not sure if it's the XFreeConfig that's faulty or the kernel
boot command.
Here are a few outputs that might be useful :

The second screen (connected to the ATI Rage) is a Apple Multiple Scan
20.
Does anyone has a setup like this working ? Should I use another Mode
with this screen ? Is my setup for the onboard video correct ?
Specially regarding the BusID config ?
Thanks for any help,
Antoine.
