G550 Unsupported chipsets (early):
Mystique (1064 and 2064)
- Millenium II (2164)
- Productiva G100 While Xorg has 2D support for these early chips, there is no 3D support yet.
Unsupported chipsets (modern):
- Parhelia P-series and Parhelia cards are supported by a binary driver provided by Matrox. The QID card is not supported under Linux at all, despite being apparently based on the Parhelia core.
IanRomanick recently added support for PCI mga G4/5xx cards. Example graphics cards:
- Millennium G450
- Millennium G400
- Millennium G200
- Mystique G200
Databooks for the G200 and G400 used to be available through Matrox' developer program, however the program seems to no longer exist.
