tags 452983 +wontfix thank you Modes is the old deprecated way to specificy modes. With RandR 1.2 drivers (you're using ati 6.7.196), the way to specify modes is ModeLine+PreferredMode in the Monitor section. Details in section III.5. of http://wiki.debian.org/XStrikeForce/HowToRandR12 I am marking this as wontfix for now. Note that Modes should still work for old-style drivers. Brice
