Description Rogelio Noriega 2001-04-12 14:33:57 EDT
When using add-on Matrox G450 graphic card on Dell WS 220 and 530, 
agpgart is not probed.  I need to force it using "modprobe agpgart 
agp_try_unsupported=1" command
Comment 1 Mike A. Harris 2001-04-13 10:40:55 EDT
We have force loaded agpgart on mga and r128 for a while now.
Comment 2 Preston Brown 2001-04-13 11:55:12 EDT
Bill, is this a agpgart driver issue with the WS220's chipset?
Comment 3 Bill Nottingham 2001-04-13 12:12:30 EDT
Probably, yes, if we need to add the 'agp_try_unsupported' parameter.
Comment 4 Matt Wilson 2001-04-17 14:51:56 EDT
as a workaround, add:

options agpgart agp_try_unsupported=1

to /etc/modules.conf
Comment 5 Matt Wilson 2001-04-17 14:54:24 EDT
please add the output of "lspci; lspci -n" to this bugreport.

I need "lspci -vn" to get the subvendor id.  This G450 card is not supported
currently.  *ANY* G450 card that shows up as G400, automatically is unsupported
by XFree86, and requires at a minimum the output of "lspci -vn" to be submitted
for the card to be detected properly in some future version of XFree86.

This is a bad side effect of using subvendor id's on PCI cards..  nothing much
can be done about it until the XFree86 team is made aware of new PCI ID's.

Comment 10 Bill Nottingham 2001-05-02 14:29:25 EDT
This is solely a kernel agpgart issue. Dunno why it's assigned
to X.
Comment 11 Mike A. Harris 2001-05-02 14:41:10 EDT
Ok, the 0641 pci id is in kudzu already.  It must have been added after
RHL 7.1 was released...

I looked into the XFree86 code and I do not see any sane way of working around
this problem inside XFree86.  If the above workaround works, please use it for
the time being.  As far as I am concerned, this is a hardware/kernel issue, not
an XFree86 issue.

Whoops.. looks like we had a mid air collision there bill..  Reassigning to
