I have a CRT connected to a RH9 machine at work which also does not give timing information using the XFree86 VidModeExtension. This means I cannot estimate its refresh rate, and I think you would get the same misinformation from DGAQueryModes, but I can check that for you tomorrow. -Billy _______________________________________________ Devel mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/devel
