Description sasamotikomi 2015-08-18 05:58:10 UTC
I can't find sysctl for changing AGP mode:
Follow Xorg wiki page http://www.x.org/wiki/RadeonFeature/
Linux value:                    FreeBSD value:
radeon.modeset 0,1, -1 -> hw.dri.0.modesetting 0,1
radeon.agpmode 1, 2, 4, 8, -1 -> not exists ? default state is -1?

It's big problem because PCI/PCIe mode of AGP causes many artifact in X11 especially in fonts rendering:

Is this still an issue with an updated xorg stack?
