But I'm probably doing something wrong because I'm a graphics noob. The machine normally uses CONFIG_DRM_RADEON, so I turned that off, and turned DRM_OFDRM on. When I boot I get boot messages but only one screen worth, the messages don't scroll at all, which is unusual. But I'm not sure if that's related to ofdrm or something else. The machine does come up, I can login via SSH. Is there some way to start X to exercise the driver from an SSH login? cheers
