something like Matrox cards Many Matrox video cards require the proprietary 'mga_hal' module to enable dual-head (G400 and earlier) or video capture capabilities (all Matrox cards afaik). Matrox has yet to release a 64-bit compiled version of this module, so while the card will work, you won't be able to use these features. and while you're at it, you can correct the spelling: Acceleration Support Reproducible: Always Steps to Reproduce: 1. 2. 3.
