Building KMS related drivers in the kernel as opposed to selecting them as modules and removing framebuffer modules may also address the OP's problem (which I suspect is caused because KMS has not loaded *before* xorg starts). > Then, try deleting your xorg.conf (if you have one) and do: > > eselect mesa set r300 gallium > > Also make sure that mesa is emerged with the "video_cards_r300" USE flag > enabled.
