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.

[ebuild R ] media-libs/mesa-7.9 USE="classic gallium nptl -debug -gles -llvm -motif -pic (-selinux)" VIDEO_CARDS="radeon -intel -mach64 -mga -nouveau -r128 -savage -sis -tdfx -via -vmware" 0 kB Total: 1 package (1 reinstall), Size of downloads: 0 kB Would you like to merge these packages?
