Yes, the revert still works. I have pretty old userspace, Fedora 14. libdrm is 2.4.22-1.fc14, mesa is 7.9-5.fc14. I don't have xf86-video-nouveau, I have xorg-x11-drv-nouveau.x86_64 1:0.0.16-14.20101010git8c8f15c.fc14 -- Paul _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
