Hi list, Firstly let me say thanks for the great work you do!!! 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=-1). Setting agpmode=1 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=-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 why I'm interested in getting KMS working properly. However, some people seem to really want suspend which currently requires radeonfb. So I'm trying to find a kernel configuration that works well for UMS and KMS!!! This is what I proposed:
CONFIG_DRM_RADEON_KMS=y CONFIG_FB_RADEON=y CONFIG_FB_ATY128=y CONFIG_FB_ATY=y So people can disable radeonfb from the yaboot prompt/conf if they want fully 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!!! Cheers Adam
