device support VGA compat Matrox MGA G200ew
I was reviewing my kernel config and seeing what devices were handled by what drivers -- and that all of them were configurable via kernel devices.
I used an lspci -bkv to show me the kernel driver being used for each device.
One that would seem to be of some importance is the graphics controller. There were some others devs that were 'unclaimed', but don't know that they have a tangible effect and have yet to try a few options, so won't bother with them here, but this one is a puzzler:
08:03.0 VGA compatible controller: Matrox Graphics, Inc. MGA G200eW WPCM450 (rev 0a) (prog-if 00 [VGA controller])
Subsystem: Dell PowerEdge T610 MGA G200eW WPCM450
Flags: bus master, medium devsel, latency 32, IRQ 10
Memory at d9800000 (32-bit, prefetchable)
Memory at de7fc000 (32-bit, non-prefetchable)
Memory at de800000 (32-bit, non-prefetchable)
Capabilities: [dc] Power Management version 1
I have tried the dev support under the 'frame buffer devs' for Matrox accel, with ghe G100/G200/... options checked 'on' (and Matrox I2C support as a module). But that modules doesn't seem to be attached to this HW.
The only other Matrox G200 related option under the DRM support, but it says it requires /dev/agpgart to be enabled. I know the computer doesn't have an AGP 'slot' (the card is built-in), but is is possible AGP would still be the choice for the interface?
Other ideas or not-supported?
Thanks!

Yes. lspci should list an AGP bridge.

X seems to know the G200eW. It may help you figuring if drivers/video/matrox/* (see matroxfb_base.c for the IDs) can be made to work with this revision or not.
No idea if in-kernel DRM support still works. Imho it will fly like a brick.

ok...then that's not the case.
It's a built-in graphics on a server, so it's not meant to be fancy.. just provide a basic console.

hmmm... so might be a matter of the driver not recognizing the card's
specific id?

yeah, well w/o agp, it's a non-issue. I.e., it flew like lead brick.
