Description of Problem:
Matrox Mellennium G450 video card was properly detected during installation;
but running Xconfigurator post-install presents me with the "Choose a Card"

Version-Release number of selected component (if applicable):

How Reproducible:

Steps to Reproduce:
1. install, card is detected as expected (though it only detects 16MB)
2. run Xconfigurator post install.
3. choose card.

It is not possible to detect RAM on these boards.
Also, the G400 and G450 use the same PCI ID.
Comment 2 Jay Turner 2002-03-20 21:21:25 EST
So it's prompted for the user to choose the card because there are two with the
same ID?
Comment 3 Mike A. Harris 2002-03-21 22:49:07 EST
No..  The G400 and G450 will both show up in the X log as being a G400.
The PCI ID's and subid's of these cards are in the pcitable correctly and
will detect properly.  What is displayed by lspci and X, will be G400.
This is because Matrox chose to not change the PCI id.  Inside the mga
driver however it distinguishes between the two using the subid/rev
properly.  New versions of XFree86 handle the purely cosmetic issue
of displaying G450 properly by checking for the subid/rev.

If you notice in the above lspci output, the first line shows G400, and
the second line shows G450.  This info, while confusing is correct.

The problem I see being reported is that Xconfigurator is not detecting
this card when ran standalone post-install.  I've had at least 4 reports
of this behaviour in the last few weeks from various people, and in all
cases so far, upgrading to the latest hwdata and Xconfigurator packages
has solved the problem.  I believe it was just a case of beta to beta
upgrade failure.  Please test with the latest packages and if it works
properly close for RAWHIDE.

right'o. will test later this afternoon.
Changing to NEEDINFO to help me remember to follow up on this.

everything works as expected. CLOSING -> RAWHIDE
