Xorg won't start on a PowerMac 9600 (ATI Mach64)
I installed Etch (4.0) on a PowerMac 9600/300 (Old World). The
machine boots fine, but I don't seem to be able to get the X server
to start. The 9600 has an ATI Mach64 PCI video card, and a Sony 17"
monitor connected to it by means of a Mac-VGA adapter. The adapter is
set to a fixed resolution of 1152x870 (but see below).
With the auto-generated Xorg.conf I get this error:
(II) ATI: Candidate "Device" section "ATI Technologies Inc 210888GX
(II) ATI: Shared PCI Mach64 in slot 0:13:0 with Block 0 base
(II) ATI: Shared PCI Mach64 in slot 0:13:0 assigned to active

Fatal server error:
no screens found
If I change the DefaultDepth parameter in the Screens section of
Xorg.conf to 16 or 15, I get:
Depht 15|16 cannot be used with this adapter
With DefaultDepth set to 8 (which seems to be the default for this
ATI driver), or commented out altogether, I get:
Linear aperture not available
I have no idea what this last error means. I also tried to change the
settings on the Mac-VGA adapter, but I got the exact same errors. So,
I'm stuck here. Anybody can give me a clue? Or, better yet, a working
Thanks in advance,
