In the source file of driver xorg Radeon o git, I can read this on lines 440/443: /* Add some common sizes */ int widths[15] = {640, 800, 1024, 1152, 1280, 1280, 1280, 1280, 1280, 1440, 1400, 1680, 1600, 1920, 1920}; int heights[15] = {480, 600, 768, 768, 720, 800, 854, 960, 1024, 900, 1050, 1050, 1200, 1080, 1200}; The info tag (768, 768) is duplicated and it's wrong, may be 768, 864. This probably result that mode 1152x864 is not set correctly. Thanks Jacob S. Preciado.
