I've been trying to get Kernel Mode Setting working on my iBook with Ubuntu= 12.04. I can only get it working by forcing PCI mode (agpmode=3D-1). Set= ting agpmode=3D1 or a higher number just results in freezing and a flashing= screen. Does anybody know how to get it working fully with agp? I've tried the Debian experimental kernel with the same results. I notice = with Fedora 16 they also recommend setting agpmode=3D-1 with a radeon card.= So I'm guessing there is no easy fix?? I've been trying to sort out the kernel configuration for ati/radeon cards = with Ubuntu. I raised a bug to build back in the framebuffers https://bugs= .launchpad.net/ubuntu/+source/linux/+bug/949288 . I'd appreciate any help = with that bug report. With Userspace Mode Setting there is nolonger any 3D hardware acceleration = (https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/946677 ) so this is wh= y I'm interested in getting KMS working properly. However=2C some people s= eem to really want suspend which currently requires radeonfb. So I'm tryin= g to find a kernel configuration that works well for UMS and KMS!!! =20 This is what I proposed: CONFIG_DRM_RADEON_KMS=3Dy CONFIG_FB_RADEON=3Dy CONFIG_FB_ATY128=3Dy CONFIG_FB_ATY=3Dy So people can disable radeonfb from the yaboot prompt/conf if they want ful= ly working KMS. I'm not sure if CONFIG_AGP_UNINORTH should be compiled as = a module or built in. We are now in kernel freeze for 12.04 so to get any= changes is going to take some serious begging!!!
