Almost every nVidia cards work with direct PCI memory access, and this method is compatible with the nVidia proprietary drivers.
To use it, you have nothing special to do, everything is done by DDCcontrol.
/dev/i2c-* devices with nVidia cards, you
must have a rather recent kernel (at least version 2.6.9).
Most nVidia cards, starting with TNT, but excluding the
most recent GeForce FX series, work with /dev/i2c-* devices. To use them, you must
load the rivafb module by
typing, as root:
# modprobe rivafb
The kernel configuration options needed to enable nVidia framebuffer and I2C support are:
The rivafb kernel module
is not compatible
with the binary nVidia X drivers, which are the only
drivers for nVidia cards to provide 3D acceleration.
This is why we recommend that you use direct PCI memory access with nVidia cards.
Most of these nVidia cards have been reported to work, but others models should also work. If yours is not listed, please send a message to one of the DDCcontrol mailing lists (see Appendix A, Report problems and successes).
