G200/G400/G450/G550 series

Matrox cards only work with /dev/i2c-* devices. To use them, you must load both matroxfb and i2c-matroxfb modules by typing, as root:

# modprobe matroxfb
# modprobe i2c-matroxfb

The kernel configuration options needed to enable Matrox framebuffer driver and I2C support are, at least:

Devices drivers → Graphics support → Framebuffer support → Matrox acceleration.
Devices drivers → Graphics support → Framebuffer support → Matrox acceleration → G100/G200/G400/G450/G550 support.
Devices drivers → Graphics support → Framebuffer support → Matrox acceleration → Matrox I2C support.
