That just means we dither down in sw/hw to 16 bit, instead of rendering at 24 and then doing no dithering at all. > Anyhow, 16bpp breaks the gdm login, and 8bpp breaks almost everything. > Strangely, if I switch from uxa > to sna, gdm is fine and the graphics is much smoother (less banding) than > with 24bpp output. Iirc SNA enables all the neat hw dithering options. It also works correctly at 16 bit, although you'll run into trouble with qt/kde stuff and with opengl apps. -Daniel -- Daniel Vetter Software Engineer, Intel Corporation +41 (0) 79 365 57 48 - http://blog.ffwll.ch _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
