[Dri-devel] AGP modes

[Gareth H. <ga...@va...>]

By default, all the drivers set the AGP mode to 1X.  To change this, use
the following in your XF86Config file:

Section "Device"
    ...
    Option	"AGPMode" "n"
EndSection

where "n" is one of "1", "2" or "4".  If it used to work for you and now
doesn't, you may want to try manually setting AGP 2X (esp. for the
Radeon).
